middleware cache problem
Hi all, I cache my view that show a list of stories, but I have also small voting button (like digg). Voting is done be middleware class (it reads user IP), so I can ask for view with list of stories and tell that this list shall be cached and I have to ask middleware for vote results. Unfortunaltely when cache is ON my middleware voting class isn't asked for voting results. What can I do to mix cache from view and live results from my middleware voting class? regards, Normanek --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: middleware cache problem
per-view cache is not a solution because I need only a method to retrieve fresh (not cached) data from middleware.

from django.contrib.auth import User

carteras_before = Cartera.objects.filter(usuarioID=user.id)
> Is this the best way of testing an object creation?
It's reasonable.
I'd probably just use count instead of len(), it should be faster and
more clearly indicates what you are testing. I'd also use assertEqual
instead of assertTrue for clarity.
before_count = Cartera.objects.filter(usuarioID=user.id).count()
...
self.assertEqual(after_count, before_count + 1)

Can't really say what's best without knowing more about your project. But, here are a few ideas to consider. Have only one user_profile model and use the auth permissions / groups system to distinguish between client/employee. http://www.djangoproject.com/documentation/authentication/#permissions Have only one (lite) user_profile model and use contenttypes framework to "connect" employee records to Employee Model and clients to Client Model. http://www.djangoproject.com/documentation/contenttypes/ Ditch/copy Django's auth and roll your own/modify it to work they way you need. -- Norman J.

I was gonna say the template . notation does not support numerical
indexes, but the docs say it does.
http://www.djangoproject.com/documentation/templates/#variables I did a
short simple test and it does in fact. This is on newforms admin
branch. Probably works with trunk as well.
Is this new? I really thought numerical indexing did not work.
Are you not using trunk? If not you should be, and if so there must be
something else going on (username instead of user_name?) as this
> User name is: {{ objectlist.0.user_name }}
should work as you expect.

Re: Why 2 servers to serve dynamic and static content?
eka wrote: > Hi, > > I'm new to django, and reading around, found out that it's better to > have 2 different web servers for django and static content. How is so? It's scalability issue. Each process of a server setup to serve dynamic content (using mod_python for instance) typically uses much more memory than a server tuned to serving just static content. So, for example (made up numbers) with X memory you can run Y simultaneous dynamic servers or 10*Y static ones. That means you can handle 10 times the (static)traffic. And when you're a huge successful site you might only need 1-2 machines to serve static content were as you'll have many, many serving dynamic content. Another reason would be to split static content from your regular hosting provider to something like a CDN or Amazon S3. Which might be cheaper / faster than your regular hosting provider. > And in deployment, how should this be? I mean, should I have 2 apache > instances? or use another web server for static content or...? If I was bothering with serving static and dynamic content separately I wouldn't use apache to serve the static content. Use something lightweight and fast like nginx or lighttpd. And depending on your situation you can get rid of apache all together and have the nginx/lighttpd proxy to something like wsgi or fastcgi django. On the other hand if I didn't expect a moderate amount of traffic I might skip the whole splitting dynamic/static content issue until and if I run into scalability issues. -- Norman J.

If you use the same code in your view as above then the ordering should
not change.
How are you displaying in template? Should be using something like
{% for article in articles %}
stuff

http://www.djangoproject.com/documentation/db-api/#in
user_ids = [u.id for u in users]
# or user_ids = User.objects.values_list("id", flat=true)
courses = Course.objects.filter(users__id__in=user_ids)
I've used 'in' with a many hundreds ids. Have no idea how performant it
is compared to other solutions.

I'm fairly certain the space indicates an urls came from an "include".
The spaces are not really part of regex.
One problem is the jss regex should not start with / since your resumes
ends with one.
Another problem is your regex's don't include ^ match start of text.
Without you t run into problems with regex doing partial match at end of
string. Just like you are having your example.
Since you omit the match start your 1st urls matches:
/resumes/jss/no-experience/
and
/resumes/anything/at/all/ending_with_a_word_and_a_slash/word/
In latter case career would be word
Your urls should be like this:
(r'^(?P[-\w]+)/$', career_list),
(r'^jss/(?P[-\w]+)/$', jss_list),

It sounds like you should read through the django documentation http://www.djangoproject.com/documentation/ and / or django book http://www.djangobook.com/ There are probably several ways depending on what you want to do exactly. Redirecting users: The standard way to redirect is to return an HttpResponseRedirect from a view. But the authentication system has a few alternatives see http://www.djangoproject.com/documentation/authentication/#authentication-in-web-requests and look for the "next" parameter. User Customized pages: The request instance that each view receives has a request.user attribute which is the current user (could be anonymous) see http://www.djangoproject.com/documentation/authentication/#users This can be used to customize the view for the user in whatever way you desire. -- Norman J.

One way to do this is to create helper functions.
def _get_artist_hometown(self):
return self.artist.hometown
list_display = ('album','release_date',_get_artist_hometown)

I believe, nay I know, relative imports are evil. It's easy to get confused which models "from models" represents. Esp when/if there are multiple models.py in your Python path. Maybe not with models.py but it happens, believe me I've wasted too much time on it. Just don't do it. But it's also wrong to tie apps to a particular site. This is bad: from mysite.myapp.models import Your models views, etc should be under myapp not mysite. and the directory(ies) were all your apps are should be on python path. Then from myapp.models import blah. For maximun portability and flexibility mysite should not appear in any import. For my projects I create a directory like /web/www.example.com/python, I put that directory on the Python Path and put all my apps plus settings.py file in that directory. some reading http://www.b-list.org/weblog/2007/nov/09/projects/ and http://www.pointy-stick.com/blog/2007/11/09/django-tip-developing-without-projects/ -- Norman J.

I assume the field names are different for different models or you
shouldn't be asking this question...
There are several ways I can think of:
Create methods in models (or do this in view) that return a list of the
field names you want displayed and another that returns the field's
values in the same order. Access them via loops in template.
Create base template and extend that with model specific templates.
Each of which knows how to display the columns for a particular model.
> {% for item in latest_object_list %}
>
{% block columns %}{% endblock %}
>
> {% endfor %}
The model speciific templates would be just the
{% extend base_template %}
{% block columns %}
{{ item.column_one }}
{{ item.column_two }}
{{ item.column_etc }}
{% endblock %}
part customized for each model. In the view select the correct template
like so:
t = loader.get_template('%s_list.html' % model.__name__)
Create a wrapper aka "interface" or "proxy" that translates a standard
set of fieldnames into the model specific fieldnames. So as far as the
template is concerned there is only one type of "model", the proxy one.

Do you use {% url %} tag in that template 'dynamic_page.html'?
and I think it's better not to use *args, **kwargs unless there is a
good reason. They tend to hide bugs.
def render_page(request, page_slug):
return render_to_response('dynamic_page.html',

The error indicates you were providing either empty string, '', or the
litteral characters '', (not sure the formating, probably is the former)
Neither of which match the regex for arg "name". "\w+" matches 1 or
more word characters.
So, I'm guessing your argument in url tag is wrong.

In other instances it might not. Very general rule: If it's doing display/formating type stuff put it in the template tag. If it's doing db stuff, calculations based on model fields, proly should be in the model.

Most systems I work on are complex multidev setups, testing setup, production (multiple web boxes, db, etc.) I have found capistrano to be an excellent tool for automating all the steps needed to deploy to the various above targets. It's in Ruby, but I was able to use it effectively and I don't know Ruby(At least I don't think I do :). It is not a simple tool though. Probably overkill for people with just a simple hosted server. I have a proj_base_settings.py that has strangely enough the base settings for project proj Each dev/test/production environment has a proj_settings.py that imports proj_base_settings.py and overrides whatever is required. This is often just setting DEBUG, email addy, and db. This file is not checked into source control. I prepend proj_ to all the settings files so I can have multiple projects in same python path with out conflicts. -- Norman J.

"Best" for what? Best has different meaning for different needs. If you know enough to ask this question you should know enough to answer it for your particular situation.

Cache middleware causing unit tests to fail
Hi, request.template is None instead of what it should be because the response is from the cache middleware. Which is fine. My question is there a good way to disable the cache middleware during tests? "good" being atleast the following. is automatic, isn't based of value of DEBUG, doesn't require changing django distro. Is there a special settings file or other file imported during tests only? thanks, njharman --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

My site was working fine. My unittests was what were in error.
Yeah there are going to be differences between production and devel. But,
personally I
believe unittests should test one thing. Not many things at once such as
cache/view/db
(as an aside I'm sort of sad django doesn't have a mock db for view unittests)
So, I think you should test your cache framework and how your app uses it, but,
those
tests should not be part of the view unittests.
I was testing that a specific template was being used to render page. With
caching the
correct behavior is to not use any template, not to render at all, but rather
to pump
contents of cache down the wire.
In my test_settings.py file I have:
# disable cache for testing
MIDDLEWARE_CLASSES.remove('django.middleware.cache.CacheMiddleware')
CACHE_BACKEND = "dummy:///"
Then run
python manage.py --settings=test_settings test
works beautifully.

For front end of AJAX, use whatever Javascript lib/code you like, Jquery is my choice. Django doesn't come with or dictate a particular one. The back end, Django part, of AJAX works exactly like any other view but return JSON or XML data instead of HTML. def my_view(request) data = simplejson.dumps(Model.objects.filter(somefilter=whatever)) return HttpResponse(data, mimetype="text/javascript") or http://www.djangoproject.com/documentation/serialization/ -- Norman J.

myview should be in the views.py of your app. The urlpatterns above is
pointing to some django views file. You shouldn't edit the django
source if you can avoid it.
urlpatterns = patterns('',
(r'(?P\d{4})/(?P\d{2})/(?P\d{2})/(?P[\w\d\-]
+)/$', "myapp.views.myview", dict(entry_info_dict, month_format='%m',
template_object_name='entry')),
)
Not sure if that caused your 404. They are usually caused by missing
data (if you used incorrect slug in url), or if regex in urlpatterns is
wrong. Turning debug=True in your settings.py should give you more
information on why there is 404's.

Re: Distributed databases
I've never seen anything that would make this "easy" in Django itself. You will probably have more luck looking into sql proxies. Django will talk to the proxy, the proxy will figure out what database to actually query and return results to Django. This way Django doesn't have to change, doesn't have to even know any thing funky is going on. Btw, Isolated layers like that is a great way to architect a system. I don't have a sql proxy to recommend, Google does though. ___ Get out and about this spring with the Statesman! In print and online, the Statesman has the area's Best Bets and recreation events.

TDD is very hard. I rarely muster the discipline to do pure TDD. But,
TDD isn't required to have unittests, which are awesome by themselves.
If you haven't already read
http://www.djangoproject.com/documentation/testing/
View tests don't have to be complex, the minimal test for a non-form
view checks quite alot:
urls.py
urlpatterns = patterns("specials.views",
url(r"^$", "ads", name="ts_ads"))
tests.py
def test_specials(self):
url = reverse("ts_ads")
response = self.client.get(url)
self.assertTemplateUsed(response, "specials/ads.html")
Basically if I write it I test it. Don't test that Django works or your
database works. They should have their own tests.
For views I mostly don't check they return the expected html(it changes
too often during development and I think that is better handled with a
tool such as Selenium). Instead I check that they use correct template,
redirect to login page, don't raise exceptions, etc. I also have
written a custom UnitTest (extending Django's) that checks for empty
template vars using TEMPLATE_STRING_IF_INVALID='test_oops_test'.
I do POST to views that have forms and check they work as expected.
Although, I usually check form validation in separate forms tests.
I check forms with any custom validators or logic.
I check every method I write for models and model managers including
things like __unicode__ via str(modelinstance).
Also, Every time I find a bug I first write a unittest that fails
because of that bug. Then I fix the bug and check unittest then passes.

Since python strings are immutable using + causes a lot of unnecessary
copying. It's probably not such a big deal in rarely executed code but
is a real performance killer in loops. For consistency and clarity,
people tend to avoid using + with strings altogether.
For example this is slow/unnecessary:
s = ""
for txt in somelist:
s += txt
print s
The Pythonic way is to use a list:
s = list()
for txt in somelist:
s.append(txt)
print "".join(s)
Joining a list of strings is neat because instead of "" you can use ", "
or "\n", "\t" which are all fairly common and join takes care of not
having a trailing ", ".

AFAIK you can't. In some places with Django you can put names in quotes
to have the same effect. See

templates always use dot notation for dictionary access
tag_dict.document.uid
But I don't think that will work inside a "for" tag and also won't work
cause you want the document.uid to be key not "document".
The workaround I'm aware of is the "with" tag.
http://www.djangoproject.com/documentation/templates/#with
something like this
{% with document.uid as uid %}
{% for doctag in tag_dict.uid %} {{ doctag.tagid }} {% endfor % }
{% endwith %}
An alternative is to pass in a context var that already has the list you
want.

With mod_python there's a directive to control whether apache automatically reloads python code. You *don't* want to set this on for production code(large performance penalty).

The standard http://www.djangoproject.com/documentation/csrf/ CSRF protection middleware does something like that. Don't know details but could look there. If you're gonna 1way hash things such as 'id' and worry about speed then store the 1way hashed value in database and do your lookups on that. -- Norman J.

Creating db column is what I did for storymash.com, for example this url http://storymash.com/u/huskerlayd/wolewadu/ "wolewadu" is a unique string used to reference individual chapters in urls and other places. It's not a hash. It's not related to id. Wanted less ugly urls than either ids or hashes provide. So it's always 8 alternating constanants/vowels with a bunch of undesirable words/substrings disallowed.

You don't need temp varible. and there is a short cut for your try/except http://www.djangoproject.com/documentation/shortcuts/#get-object-or-404 This would do def adopt_bunny(request, id): bunny = get_object_or_404(Bunny, pk=id) bunny.adoption_count += 1 bunny.save() Don't know why it would inc by 3 or 4. Assuming you are running dev server... I'd add a print statement in there print "bunny %s: %s" % (bunny.id, bunny.adoption_count) just to see when/if this code is being called multiple times and the value of adoption_count when it is. Maybe add print to Bunny's save method to see where else it is getting modified/saved. Also I'd probably make a method in the BunnyModel instead of doing this in the view. Maybe overkill for this case (but today's overkill is tomorrow's maintenance saving feature) Bunny(Model): ... def adopt(self): self.adoption_count += 1 self.save() Then from your view call it def adopt_bunny(request, id): bunny = get_object_or_404(Bunny, pk=id) bunny.adopt() return single_bunny(request, id, True) -- Norman J.

It sounds like some other exception is, sadly, being masked by the transaction abort exception. Unless you know and like to use debuggers, the answer is almost always more print statements :) I suspect that the file you are reading isn't properly formated csv, or the data in row[0] or row[1] aren't what your database expects, or some other error like that. What you need to do is figure out what is actually being sent into OrderEmail and why that is causing database to choke and rollback. for row in reader: try: print row print row[0], row[1] b = OrderEmail(name=row[0], email=row[1], been_sent="0") b.save() print "saved", row except Exception, msg: print msg I have no idea what OrderEmail is about but this been_sent="0" looks suspicious.

I've used low-level api
http://www.djangoproject.com/documentation/cache/#the-low-level-cache-api
And I'm caching context vars, but no reason can't be done in template
tag. Probably cleaner that way.

I'm not 100% familiar with Template Tags, but I thought you'd want to do
the "work" once in init instead of every time in render.
You're not doing it low-level enough :) You're trying to put a QuerySet
into the cache. I think you want a single random Ride that would be
Ride.objects.filter(site=settings.SITE_ID).order_by('?')[0]
Even with a Ride instance instead of a QuerySet you need to pickle it to
store in cache and unpickle when you pull it out. (I don't *think* that
happens automatically)
Instead I'd store the specific values of Ride I want to use.
cache.set('rod_title', ride_title, 24*60*60)
cache.set('rod_img_url', ride_img_url, 24*60*60)
The template tags I've created in past tended to create snippets of html
instead of just setting context vars. I'd stuff that "rendered" html
into the cache.
This is code I've used to do things of day/hour in views. It could be
adapted to template tags.

Sounds like you have caching disabled or are using something like

Any other ideas or suggestions? Simplest and scalable aren't often achievable in the same sentence. Unless your site is very low traffic the thing you don't want to do is write to the database every view. That is anti-scalable. For one project in the past a coworker came up with this: write log files to a ramdisk, one line per view(fast + simple). A cron job slurped the files, did unique views logic, other stuff and updated a times_viewed field in the models. Scaling that to more than one machine adds complexity. I'd probably pursue a different solution when/if traffic warranted it. -- Norman J. Harman Jr. 512 912-5939 Technology Solutions Group, Austin American-Statesman ___ You've got fun!

Specifically they know best what their address is and how it should be formated. Users are more likely to know about changes to their countries addressing scheme. Etc, etc. With that in mind the best way to handle varying international addresses is with a largish char column backend and multiline text input box on frontend. -- Norman J.

Template's white space handling is one of the few things that irks me
about Django. I hate having to make confusing formating, jamming stuff
all on the same line just to get white space correct.
I really wish it had some whitespace handling tools like Cheetah
http://www.cheetahtemplate.org/docs/users_guide_html/users_guide.html#SECTION00068
The spaceless tag helps sometimes, but not for your situation.

What I'm use to is less of particular tag and more of a change to how
all tags/templates work. In short, lines in templates that have only
tags should be "invisible" i.e. they should not be in the output of that
template.
If after doing tag processing a line(that had 1+ tags to begin with)
consists of nothing but whitespace then eliminate that line, including
it's new line.
line numbers for ref:
1: {% if bar %}bar{% endif %}
2: {% for i in list %}
3: i
4: {% if False %}{% endif %}
5: {% endfor %}
6:
which now creates something like this when bar=False, list=[1,2]
1:
2:
3: 1
4:
3: 2
4:
5:
6:
instead outputs this
1:
3: 1
3: 2
6:
But this is a backwards incompatible change, a minor issue, and with
effort it's possible to work around this issue just not beautifully
(which contrasts with the rest of Django).
Other stuff is higher priority and the real problem with Django is
http://superjared.com/entry/real-problem-django/. I didn't mean to
sound complainy in previous post, if anyone took it that way.

I've been using python since 1.5, I had to look up what vars() did.
Probably not idiomatic Python. (I've always just looked at __dict__
directly, which I do rarely).
The assertEqual line (probably) fails because the order of dictionary
keys is not defined.

FWIW I believe testing what you're testing is a waste of time and
violates unit testing. Really the db should be mocked, but that is
fairly hard. If you didn't write save(), you shouldn't be testing it.
But, if I were testing this I think I'd do something like this
assertEqual( db_mo, mo, "local and db versions of %s not
identical" % mo.__class__)
In general, I trust == (either Python's or the object's author's) more
than poking into the internals of an object, encapsulation and all that :)
When I compare dictionaries I either convert them to sorted tuples (to
put keys in proper order)
expected = dict(var1="dog", var2="cat")
answer = something_that_return_dict()
assertEqual( sorted(expected.items()), sorted(answer.items()) )
Or check only certain keys are equal (for instance if the answer dict
has other stuff in it I don't care about)
check_these = ["key1", "key3"] # = expected_dict.keys()
answer = something_that_return_dict()
for k in check_these:
self.assertEqual( expected_dict[k], answer[k],
"expected[%(key)s] != answer[%(key)s]" % {"key":k} )
For Models in which I write a custom save method this is how I usually
structure it.
def save(self):
if self.value is None:
self.value = self._calc_value()
super(FooModel, self).save()
def test_value_on_save(self):
test_data =( (dict(foo="", bar=""), 42 ),
(dict(foo="1", bar="3"), 37 ),
# test more edge cases, etc.
)
for (expected, data) in test_data
t = Model(**data)
t.save()
self.assertEqual( expected, t.value )
If I had another custom value I'd write another test for it.
Good luck with your continued Python adventures,

I had to do something similar for PayPal. I did it by changing the action="" in a confirmation form to point to PayPal. Instead of form POSTing back to me and trying to redirect POST which doesn't work, it POSTs directly to PayPal. The form was constructed to contain all the things PayPal wanted in hidden fields. In PayPal's instance it doesn't matter that user can change values(they are checked elsewhere, when PP notifies us of payment) but it may in your situation. Depending on what 3rd party site does/wants another way to do this is to use something like urllib2 and POST to 3rdpary in your view code, slurp the response and send it back to user. It will have 3rdparty content but come from your server, which is probably gonna cause problems. -- Norman J. Harman Jr. Senior Web Specialist, Austin American-Statesman ___ You've got fun!

I'm not sure. I'm distraught over having validations in two places the
model and forms that "feed" that model. And form_from_model or whatever
it is called is never what I want. I tend to test the forms as I tend
to manipulate models through forms and the forms support much richer
validations than FooFields do.
Blank is an admin thing and I typically don't test those. Testing
Nullable field(s) would be data point(s) in creation/save test.

Don't construct dict like that, make a list instead.
[ {'post': 'My First Post', 'title': 'My First Title'}, {'post': ... ]
Or, if you don't have control over dict construction, munge it into list.
If order isn't important:
list_o_dicts = dict_that_should_be_list.values()
If order is important:
list_o_dicts = [ dict_that_should_be_list[k] for k in
sorted(dict_that_should_be_list.keys()) ]
Then you can use the template for loop construct normally
{% for dict in list_o_dicts %}
{{ dict.post }} {{ dict.title }}
{% endfor %}

First guess, curious if others think its good idea. Create model with one2one nullable field "suggestion" and Boolean field "is_suggestion". If suggestion is Null then there is no suggestion. If suggestion is not Null it is id of suggested data. The idea is to avoid maintaining two duplicate schemas. Proly change the default Manager to only show is_suggestion == False rows. def suggest(self, obj): """obj is original obj self is suggestion for"" self.is_suggestion = True self.suggestion = obj self.save() def accept(self): "accept this suggestion" assert self.is_suggestion # need more logic if model has foriegn relationships self.suggestion.delete() self.suggestion = None self.is_suggestion = False def reject(self): assert self.is_suggestion # not sure how to delete relation # self.suggestion.suggestion = None ??? self.delete() -- Norman J.

correct list for newforms admin questions? named urls / replacing admin root page
I want to use {% url %} to point into portions of the admin site(and
change the default url structure). I hacked this generally
unfullfilling but working version with old admin.
model = dict(app_label="specials", model_name="adspecial")
urlpatterns += patterns("django.contrib.admin.views.main",
url(r"^$", "change_list",
name="ts_admin_special_list", kwargs=model),
url(r"^add/$", "add_stage",
name="ts_admin_special_add", kwargs=model),
url(r"^(?P\d+)/$", "change_stage",
name="ts_admin_special_edit", kwargs=model),
...
)
Not sure how to do this with newforms. I got this to work, but I really
don't want to make wrappers to get the dynamic urls to work.
url(r"^$", site.root, name="ts_admin",
kwargs={"url":"specials/adspecial"}),
Actually, I'd really love to learn a cleaner way to do this. Main goals
are to have a custom admin "index" page, and not hard code urls.
Thanks,

Actually, I figured out this workaround. Which I call "not pretty, but
mostly works".
# tie into django user mgmnt
user = kwargs=dict(app_label="auth", model_name="user")
group = kwargs=dict(app_label="auth", model_name="group")
urlpatterns += patterns("",
url(r"^auth/user/$", admin.site.root,
{"url":"auth/user/"}, name="dj_user"),
url(r"^auth/user/add/$", admin.site.root,
{"url":"auth/user/add/"}, name="dj_user_add"),
url(r"^auth/user/(?P[^/]+)/$",
admin.site.model_page, kwargs=user, name="dj_user_edit"),
url(r"^auth/user/(?P[^/]+/password)/$",
admin.site.model_page, kwargs=user, name="dj_user_passwordchange"),
# "catch" other urls we don't care to name
(r"^(auth/.*)$", admin.site.root),
)
Has problems with deep linking cause
self.root_path = re.sub(re.escape(url) + '$', '', request.path)
is only in def root(...) and not in def model_page(...) or constructor
or something.

If the function takes no parameters and returns a string, you can pass
it in the context and call it like a variable.
{{ myfunction }}
I believe this will call the function each time it is used. I'd
probably do something like this instead.
def my_view(request):
extra = dict()
extra["message"] = myfunction(args, and, stuff)
return render_to_response("mytemplate", extra)

Figure out which Python is default. # this gives you the version python -V # this tells you were it is (and around where setup.py install will put its files) which python If the default is /Library/Frameworks/Python.framework/Versions/2.4/lib/python2.4/bin/python but you want to use /usr/local/python2.5/bin/python instead then you must make sure you run the correct python when doing installs and when running manage.py. you can use the full path every time /usr/local/python2.5/bin/python setup.py install or you can use an alias (I suggest adding to your .bashrc or similar file) alias python=/usr/local/python2.5/bin/python -- Norman J.

I don't think that's bad, all depends on how you want UI to work. Other options would be putting them in a ChoiceField and using Select (dropdown) RadioSelect (radio buttons) or some custom widget. The choice field options will have only one delete button but require user to select which record to delete. That may or may not be a better ui than multiple delete buttons. -- Norman J.

By "root" do you mean the url that arrived at the template is a "/" root
url.
If so, I would determine this in the view and pass in a template
varible, 'is_root'. But I don't think wrapping an extends in a if/endif
will work.
Or do you mean the template is root as in it doesn't extend any other
templates.
In that case just skip the if/endif because a template only extends
another if you tell it to.

Thanks so much! Rule 1: Don't use globals. Rule 2: Don't try to store state in a stateless server, use persistent storage like a DB. There *are* two or more copies of the global. There are as many copies as WebFaction runs instances of django (mod_python or whatever) It works in dev cause manage.py runserver only starts one instance of django. -- Norman J.

Are you sure it happens in IntegerFields, that's surprising. That blog is talking about CharFields for which saving "" for None is less surprising. Instead of mucking with model's save method I'd create my own field, NullCharField or NullIntegerField that replaces "" or None with NULL according to the null=true parameter. -- Norman J.

I don't know what ver of Django you're using by my version certainly appears that it doesn't perform the way you say it does. i.e. it looks like it does not allow "" for Integer fields. from '/django/db/models/fields/__init__.py' class IntegerField(Field): empty_strings_allowed = False Although, It's possible my 3min analysis of what empty_strings_allowed does is wrong. You'd have to look closer at the above file but it looks like overriding this def get_db_prep_save(self, value): "Returns field's value prepared for saving into a database." return value is what your after. I've not done this before though so "caveat programmer". btw, I really think IntegerField is the wrong column type for a zip code. They can be upto 11 chars long and have hyphens. I'd make it CharField or maybe even a USZipCodeField from 'contrib/localflavor/us/forms.py' There's many others in localflavor if your flavor isn't US. -- Norman J.

Re: Stability of trunk and 1.0 target: experience, testimonials?
I've been using trunk for over 9mo for in production website http://storymash.com During that time, there's been 2-3 times my unittests have failed after I've svn updated django. Each time was a fairly quick fix. API changes aren't hard bugs to track down and fix. The advantages of all the great stuff that has been added to trunk far outweigh the time spent. In fact, I've learned a bit about Django internals tracking down those failing unittests. My current employer, uses .96 or newforms-admin/trunk for several minor but still business critical and public facing portions of it's websites statesman.com and austin360.com with *no* problems(well no Django problems anyway ;). The .96 projects started before I arrived or else they would probably be trunk as well. I've been nothing but impressed with the diligence and abilities of Django developers and community to maintain multiple stable branches. Compare Django release discipline and record to other major frameworks. And your PHB's should be scared to use anything but Django. -- Norman J.

Really? I was sort of hoping with model inheritance and newforms-admin I
would finally be able to get rid of user profile. It was a useful hack
but now that there is a general solution the special case should be
disfavored, no?
Maybe I'm using it wrong. I dislike having to user.get_profile.myvar
select_related doesn't seem to apply to user profiles and in a template
loop of say blogs the "caching" fails.
{% for blog in blogs %}
blog.author.get_profile.something
{% endfor %}
If there are 10 blogs by the same author then there are 10 hits on
user_profile to read it each time.

Test system creates a new test database from scratch every time it is
run. manage.py loaddata has NO effect on test.
I could be wrong but I don't believe test runner automatically loads the
fixture initial_data.xml
You need to tell it what fixtures to load and you need to put them in
the correct place.
