I won't give a recommendation and will let others speak up. That being said, there's still some advice I'd like to give. Some of these packages have different goals than other: FeinCMS and Django-CMS are primarily page oriented CMS. Both have plugins, which can be used to integrate other types of content than only rich text / plain text content snippets. On the other hand, simplecms and PyLucid offer more modules for structured content (like articles, blog entries etc) and therefore do more, but you might not need all functionality they offer. Using those might give you a head start compared to Django-CMS or FeinCMS though, but I'm not sure about that because I've never taken a deeper look at them. google-sites ... this is a list concerning Django, so google sites is off-topic, and I'm not sure whether you can use google sites for your own webpages at all, at least if you have requirements for styling, functionality which do not align well with what google sites is currently offering.

Thanks for the heads-up about working in the shell. I have found out
more useful commands and syntax in doing so (e.g. showing the SQL from
the query via my_query.query.as_sql() ).
I had the right idea (e.g. I was working with the {% for result in
results %} loop, even though I did not indicate that to the original
question) . The root of the problem was that my model relationships
were incorrect i.e. D <- C -> B -> A and so I had to restructure the
query.

MacPorts installation, Django $PATH issue
Hi everybody I just got Django installed (to test it) via Macports and I have Python 2.5 and 2.6 installed on a MacBook running 10.6.3. I did everything the installation guide told me, but after typing: python manage.py runserver I get this error: File "manage.py", line 2, in from django.core.management import execute_manager ImportError: No module named django.core.management I believe the solution would be this comment on the installation site: To avoid a command not found issue with Snow Leopard 10.6.2 and various other OSX (Django installed using MacPorts?) here a tip that might help. There might be a $PATH issue. Adding the proper PATH to ~/.Profile: export PATH=/opt/local/bin:opt/local/sbin:/opt/local/lib/ python2.4/site-packages/django/bin:$PATH should help. NB Could be that one needs to change the Python version in the PATH. But I dont now what a $PATH issue is and where I could paste this code to fix it. Or if you know another possible reason please tell me. Any help would be greatly appreciated.

access value from request.GET.get in request.method == 'POST
Hi to everybody. I am a django and python newbie and I hope that
someone can help me here.
This is my first post here.
I will first explain my problem very abstractly to confine myself to
only the bare necessities.
I define a function "process" in a views.py file.
BEGIN Code
def process(request, template_name)
token = request.GET.get('token', ' ')
...
if request.method == 'GET':
some_details = getDetails(token)
if 'Success' in some_details['ACK']
email_adress = some_details['EMAIL'][0]
first_name = some_details['FIRSTNAME'][0]
...
return render_to_response(template_name, --->
locals(), context_instance=RequestContext(request))
if request.method == 'POST':
details_response = doSomething(token = token) # everytime I
enter this, I get empty token
if 'Success' in details_respone['ACK']:
...
else:
error_code = details_response['L_ERRORCODE0']
return render_to_response(template_name, --->
locals(), context_instance=RequestContext(request))
END Code
My question is: how can I access the value for token when polling the
if request.method == 'POST'
I would appreciate any help.

Multiple aggregates within the same aggregate(), I'm 99% sure, are put
into a single query, at least if they're simple and not spanning
complex relationships themselves.

Yeah, that's a tricky use case no matter what. I don't think there's a
way out of *something* doing some heavy lifting, whether it be python
or the db. But as I've seen mentioned many times (often by
Malcolm...where's a Malcolm bat-signal when you need one? I'd love to
hear his thoughts on this) the ORM isn't designed and can't be
expected to handle 100% of cases. This may indeed be a situation where
a simple extra() actually *is* the elegant solution.

Certainly agree with this.
Sorry I couldn't be more help!

Re: access value from request.GET.get in request.method == 'POST
First thing would be to ensure that when you submit the form back to
itself, the querystring remains. It's all well and good to visit a
form like this:
/someapp/myform/?token=blah
But if your HTML form tag is:
Then you'll lose the "?token=blah" part when you submit.
Other than that, nothing I can spot in there that would case token to
be blank. In other words, a request made with POST still has any
arguments in the querystring accessible via request.GET.
I'd break the code right after you extract the token:
token = request.GET.get('token', ' ')
assert False
...and inspect the value of token in the state output. If it looks
fine there, just keep moving that "assert False" down till you find
where the value is getting lost.

Re: where can I find good unit test examples?
Hi Chris, First of all, I never had much luck writing reproducible tests for Django models with the fixture system that comes built into Django as I never got consistent results and found the XML a pain to maintain. I came across Fixture - http://code.google.com/p/fixture/ We have this running with our Django installation for all our unittests and it works a treat. There are some examples of unittests in the source for that. I've used that in an open source project called Django audit to test some model related bits and pieces, but I wouldn't necessarily attest to their being "good tests" as it's a work in progress. Have a look at https://launchpad.net/django-audit/ in the tests section. For good unittesting in general in a Django type manner (but not specifically model related) have a look at http://pypi.python.org/pypi/twod.wsgi/ Hope this helps, Euan On May 6, 9:23 am, Chris Withers wrote: > Hi All, > > Where can I find good examples of django unit tests? > > I currently just want to test my models and some helper functions, but > they will do a .save() on a bunch of model instances. > > Any help gratefully recieved! > > Chris > > -- > You received this message because you are subscribed to the Google Groups > "Django users" group. > To post to this group, send email to django-us...@googlegroups.com. > To unsubscribe from this group, send email to > django-users+unsubscr...@googlegroups.com. > For more options, visit this group > athttp://groups.google.com/group/django-users?hl=en. -- You received this message because you are subscribed to the Google Groups "Django users" group.

Converting a urlib2 response to a django one

I mean, elements like, the mimetype, the Content-Disposition, etc. Is there a better way to convert a urlib2 response to a django one?

Re: Disabling (or find a workaround for) the comment security checks
Disclaimer: Disabling the security stuff makes it really likely you'll get comment spammed. You should set up some kind of akismet protection on the backend if you disable the security. If you don't want the checking then you probably want a custom comment form. You can use this method to setup a new form: http://docs.djangoproject.com/en/dev/ref/contrib/comments/custom/#django.contrib.comments.get_form Then use the form base classes with the functionality you want. (You'll probably want to exclude the CommentSecurityForm, and include the generic foreign key information some other way.) http://docs.djangoproject.com/en/dev/ref/contrib/comments/forms/ Hope that helps!

Re: Converting a urlib2 response to a django one
Hi,
Thanks for the reply! This looks neat. Although, right now I would
rather not depend on two additional packages if I can :\
I think I'll settle with copying a few headers manually for now:
def digitalObject(request, id):
import base64
import urllib2
url="http://some.url.com/somefile";
req = urllib2.Request(url)
resp = urllib2.urlopen(req)
objfile = resp.read()
response["Expires"] = resp.info().getheader("Expires")
response["Content-Disposition"] = resp.info().getheader("Content-
Disposition")
response["Date"] = resp.info().getheader("Date")
response["Content-Type"] = resp.info().getheader("Content-Type")
return response

Re: Working out some custom API stuff
Thanks for the help on that portion, it is working wonderfully.
I've been able to power through most of the requests for this project
but there is one outstanding element in regards to pagination.
Here is my view:
def QandAAPI(request, site):
quest = entry.objects.filter(site__name__icontains=site)
if 'id' in request.GET:
ids = request.GET.getlist('id')
quest = quest.filter(id__in=ids)
if 'sect' in request.GET:
sect = request.GET.getlist('sect')
quest = TaggedItem.objects.get_by_model(quest, sect)
if 's' in request.GET:
s = request.GET['s']
search_query = (
Q(question__icontains=s) | Q(answer__icontains=s) |
Q(answerer__icontains=s)
)
quest = quest.filter(search_query)
if 'count' in request.GET and not 'page' in request.GET:
count = request.GET['count']
quest = quest[:count]
if 'count' in request.GET and 'page' in request.GET:
page = int(request.GET['page'])
count = request.GET['count']
paginator = Paginator(quest, count)
try:
page = paginator.page(page)
except ValueError:
page = 1
json = serializers.serialize("json", quest)
return HttpResponse(json)
I am getting the following error when I try to plug a page=1 into the
URL
coercing to Unicode: need string or buffer, int found
I'm not entirely sure how to fix this error, I've tried many times.
The final view should do the following:
Check to see if 'page' and 'coutn' are part of the url. If they are,
then pull up the results of that page with the count declared in the
URL.
There will be another component that will skip the 'count' if it isn't
declared but I haven't got there yet.

Re: where can I find good unit test examples?
Perhaps I'm missing something, but when I run "manage.py test", the system sets up a test database So you should be able to create all the model elements you need, and save them and change them -- whatever. In fact, what I do is during the setUp(...) routine, I add my "stock" test data. It'll create 1000ish records with proper references. This is all done within the confines of the Django framework. Then, in tearDown(), I delete all the data and the next unit test re-setups... My implementation actually uses a base class. In this way, I can have multiple base unittest classes that setup data in a particular way. This design not particular efficient -- it's contently creating and deleting data. But it does satisfy the standard unit test requirement that each test is independent of other tests. Either order or expected data. While I'm sure it has it's down falls, it works very well for my system.

Django App and Memory Mgmt
I have a Django app that selects one of many possible XML documents, parses it with minidom.parse(), finds all elements of a certain tag with getElementsByTagName() then it sends a small subset of those elements off to a client browser. So I typically have to parse many thousands of elements to make the DOM object to then get the appropriate 50 or 100 element portion that will be sent off to the user as a smaller XML file where it is parsed at the client side with javascript. My memory performance with Apache and mod_wsgi isn't very good, and I assume that's because I parse the whole file into memory, and also because getElements creates another large object before I can extract my desired elements. I do a bit of scrutinizing and massaging of them before they get wrapped up and sent on. I'd like to call unlink() on the big objects, but I don't know that I can do that somewhere, as I 'return' the small subset, and I don't have control after that is returned by Django to the requestor. Any thoughts on a) is this a big contributor to my memory footprint? b) wouldn't this all be garbage collected after the response is handled anyway? c) would I be better off with a SAX parsing of the XML file to avoid building the whole DOM tree to get my small subset of objects? Your thoughts appreciated. Is there a better way? I wouldn't want to stuff the XML-file resident content into a database and rebuild the XML element subsets because there are tons of files arriving and disappearing and it would become a huge background activity for another program.

If each xml element is used very few times, but you think a good proportion of them is going to be required before becoming outdated, then you could preprocess them as they arrive, instead of waiting for the request. i guess that processing a whole document would produce several results much faster than searching each individually. to avoid the load on a RDBMS, you might find better to store the preprocessed results on a key/value store, maybe even a memory-resident one, like redis. -- Javier -- You received this message because you are subscribed to the Google Groups "Django users" group.

Re: Django App and Memory Mgmt
Reading more it sounds like the memory usage issue, particularly for those exploring Webfaction, is a typical rite of passage, and probably has more to do with httpdconf and mod_wsgi setup than it does with Django practices.

Re: Django App and Memory Mgmt
You may want to consider using a sax based parsing. It works by calling you back for beginning of tag (has the attributes), text content, and end of tag, from which you can keep state and just keep the, you say small. subset of the element data that you need, which you can either stick in a dom, or have your own object structure that you know how to render for the requester. Much more coding than the dom, but you don't need the whole document in memory at once.

need help with custom authorization Backend

return None

his/her

print " in my backend group perm"
role = Role.objects.filter(user__exact = self.id)
if role is not None:
perms =
role.permissions.values_list('content_type__app_label', 'codename')
return set(["%s.%s" % (ct, name) for ct, name in perms])

Re: Password reset email sent several times
You have five different users in your database with the same e-mail address. If you look at the e-mail messages, you'll notice that each one specifies a different value for username.

Re: MacPorts installation, Django $PATH issue
Type "which python" at the command line as your regular user. Then, look at /usr/bin/python*, /usr/lib, /usr/local/bin/python* and /usr/local/lib. Find where the site-packages for Django are located. Make sure that "which python" is pointing to the correct version. Sounds like Django is not installed in the same version of Python that you are actually using. Also, if you type python -V (I think it's a capital "V") at the command line, it should tell you which version you are using.

Close window after download
I have code that generates a file for download. I want to close the window after the user selects the download or even redirect them. Here is my code: response = HttpResponse(cal.as_string(), mimetype='text/calendar') response['Content-Disposition'] = 'attachment; filename=schedule.ics' return response I can't close the window before the download using because I get an error that the window closed. So after the form download the window is hanging in limbo. If anyone knows how to close the window I'd appreciate it. -- You received this message because you are subscribed to the Google Groups "Django users" group.

Re: Insert model data into every page (base.html)
If you use the context processors, you can include the data on every
page. The template should be rendered from the view or in your case a
generic view.

Error with passing 'form_class' arg with Django Contact Form
Hi All,
Bashing my head against a wall trying to understand this issue.
Playing around with Django-Contact-Form app, and trying to use my own
subclassed Form in the views. From the code in views, it looks like it
just takes an optional arg, form_class, which can be your Form
subclassed from ContactForm. Here is my Form class:
from contact_form.forms import ContactForm
from django import forms
attrs_dict = { 'class': 'required' }
class EnhancedContactForm(ContactForm):
def __init__(self, data=None, files=None, request=None, *args,
**kwargs):
super(EnhancedContactForm, self).__init__(request, *args,
**kwargs)
I know it doesn't do anything, was just trying to get the simplest
form to work first. Here is my urls.py:
urlpatterns += patterns('',
url(r'^contact/$',
contact_form,
{'form_class':EnhancedContactForm},
name='contact_form'),
url(r'^contact/sent/$',
direct_to_template,
{ 'template': 'contact_form/
contact_form_sent.html' },
name='contact_form_sent'),
)
It fails with the stack:
TemplateSyntaxError: Caught an exception while rendering: unbound
method __unicode__() must be called with EnhancedContactForm instance
as first argument (got nothing instead)
Original Traceback (most recent call last):
File "/Library/Python/2.5/site-packages/django/template/debug.py",
line 71, in render_node
result = node.render(context)
File "/Library/Python/2.5/site-packages/django/template/
defaulttags.py", line 155, in render
nodelist.append(node.render(context))
File "/Library/Python/2.5/site-packages/django/template/debug.py",
line 87, in render
output = force_unicode(self.filter_expression.resolve(context))
File "/Library/Python/2.5/site-packages/django/utils/encoding.py",
line 71, in force_unicode
s = unicode(s)
TypeError: unbound method __unicode__() must be called with
EnhancedContactForm instance as first argument (got nothing instead)
If you substitute the standard ContactForm in urls.py, it fails the
same way.
Anyone seen this before? What am I doing wrong?
Cheers
Ricko

values() and GenericRelation
Hello,
I need to put into a template some fields of my model, but not all the
fields, it is better to specify which fields to pass.
Then, I use something like:
MyModel.objects.values('id', 'field1__name', 'field2',
'field3__value', 'my_custom_set')
But, 'my_custom_field' is a GenericRelation field, and I can't specify
it as parameter of the QuerySet values() method.
The error is:
Exception Type: FieldError
Exception Value: Invalid field name: 'my_custom_set'
Note I've already read that values() method doesn't return anything
for M2M fields attributes, but not sure if a GenericRelation is really
a m2m field relationship.
(http://docs.djangoproject.com/en/1.1/ref/models/querysets/#values-fields)
However, if I give to the template the full list of fields, it works,
for example, using:
MyModel.objects.all()
I could use all() result, but I must use the ForeingKey values of the
field1 and field3, so I don't know how to get its values if it not the
way I said before.
How can I resolve this?
Thanks your comments, and if it's not clear, please tell me, i'll try
to clarify my problem.
Regards,
Caio

Errors while attempting to enable admin
Django newbie here. I am learning by following the Django book. All
is good until I try to enable the admin interface (on v1.1.1) and I
get the following error:
TemplateDoesNotExist at /admin/
admin/login.html
So I did some poking around and changed my TEMPLATE_DIRS to the
following (which I don't think was the right way to do it anyway):
import os.path #import so we can use magic for the template import
TEMPLATE_DIRS = (
os.path.join(os.path.dirname(__file__), 'templates').replace('\
\','/'),
'/usr/lib/pymodules/python2.6/django/contrib/admin/templates/',
)
When I do that I get:
TemplateSyntaxError at /admin/
'adminmedia' is not a valid tag library: Could not load template
library from django.templatetags.adminmedia, No module named
adminmedia
This is a 'vanilla' ubuntu django install (I didn't pull from SVN) so
I am hoping that this is a well-known issue, I read the comments on
the book site and none appeared to be this issue.
Can someone give me some pointers?
Thanks in advance.
