You can override django.db.models.sql.compiler.SQLUpdateCompiler.as_sql()
method [1], and then make a custom database backend, which would point to
your modified compiler ([2], [3]).  Or you could monkey-patch Django's compiler.
Feels somewhat hackish, but should work :).

As the traceback kindly explain, the dinette.models module is trying
to access non-existing attributes of the settings module. You'd need
to define LOG_FILE_NAME and LOG_FILE_PATH in your settings or use
getattr(setting, "ATTRIBUTE_NAME", default_value) instead (cf Python's
doc for getattr).

As a side note, configuring the logging module in a models module is
definitly *not* a good idea. If you're using django 1.3+, there are
better ways, please refer to the relevant doc.

Middlewares are only used in the request/response cycle. Not the right
place for db-level stuff.

@OP: I think your better bet would be to implement your own db
backend, deriving from django's mysql backend.

Saint Petersburg Django meetup!

[Valentin Golev]

Hello, my fellow Django users!

I'd like to invite you a meetup of Django users in Saint Petersburg,
Russia, this Saturday. We think that the growing more than ever
community of developers who use Django in Petersburg is overdue to
meet, drink some tea and talk about the future.

If you live in Saint Petersburg or going to be visiting SPb on
Saturday, please come and meet us. The meeting will take place at
"HomeWork", Ulitsa Rubinshteyna, 15/17, ap. 259. We're going to start
at 15:30, Saturday, 16th of July 2011.

For more information, please take a look at http://vkontakte.ru/event28601307.
If you don't use this website, you can also read more at
http://pep8.ru/event/2/post/2 . Please take a look at one of these
webpages to avoid problems with getting into the venue.

Our page at Lanyrd: http://lanyrd.com/2011/djangotea/

Please help us spread the word: tell your friends and colleagues about
our meeting.

If you have any problems, you can ask in this thread or contact me
directly: v...@whitescape.com.

Thank you. Looking forward to see you at the meeting!

Re: Getting a subclass from an abstract Model

[gontran]

Hi Micky,

sorry for my late answer but I havn't been working this week-end.
I just tried your trick but it doesn't work. I don't think it's a
probleme of manager, because if I want to query a subclass directly by
its name, it works:
ClassA.objects.all() works normally.

Re: Model translation

[Uros Trebec]

Did anyone try "django-nani"?

https://github.com/ojii/django-nani

I'm giving it a go with my multilingual project and it kind of works.
The translating part works nicely, the biggest issue I have is the
limited AdminModel functionality (
http://django-nani.readthedocs.org/en/latest/public/admin.html#modeladmin-apis-not-available-on-translatableadmin
).

But other than that, looks promissing.

I'd say (though I may be absolutely wrong) that this is caused by the
fact that model classes are processed by the ModelBase metaclass. My
guess is (and it is really just a guess, since I can't find anything
more about __subclasses__ than that it exists [1]) that __subclasses__
returns a reference to the original class as defined in the Python
code, before it is processed by the metaclass.

Looking at one example abstract model class I have in my own project,
this appears to be the case. In the class returned by __subclasses__()
of the abstract class I see only things defined in models.Model and in
the abstract class, but none of the fancy stuff (like model fields or
managers, i. e. the stuff that is processed by the metaclass) I
defined in the concrete model.

You may be right but like I said, I will do differently:
for s in MyBaseModel.__subclasses__():

MyClass = ClassA
elif s.__name__ ==  "ClassB":
MyClass = ClassB

it was so simple!!!

The bug is in this line. render_to_response() takes a dictionary as the
context_instance, but this code just passes the request instance.

You probably meant either:

return render_to_response(template_name, locals(),
context_instance=(request, ))  # Note comma

or

return render_to_response(template_name, locals(),
context_instance={'request':request}))

Actually atomicity is preserved for updates, as all updates go to the L2
cache servers (so are as atomic as memcache over multiple servers is). The
main gotcha is that you have to be happy that different servers can have
values that are up to N seconds out of date - but generally that's not too
bad, as it's pretty much the same situation as using a reverse proxy cache.

Can't recommend Tsung highly enough. It Just Works for testing large numbers
of concurrent connections, which is more than I can say for other tools I've
tried (apachebench, JMeter, swarm of bees). There's several companies around
that offer to do high load testing but last time I checked their rates were
sky-high.

Indeed, it's on the to-do list to try comparing the performance of
Apache/mod_wsgi with nginx/uwsgi, but my gut feel is that the webserver +
WSGI container makes only a marginal difference to the overall site
performance. Of course, I Could Be Wrong.

What benchmarks would you like to see? We sustained 10K writes/second into a

After 2 years of continuous development on uWSGI, i can confirm you that
performance impact is pratically non-existent (most of the time, when you
see extreme favorable benchmark for uWSGI/gunicorn/fapws/flup/.../ against
mod_wsgi they are caused by the lack of apache skills of the guy doing the
benchmark)

Obviously you can tune uWSGI a little bit more that the others, but what
is the purpose of gaining 3% on a Hello World ?

As a proof, gunicorn and fapws, even if being coded in pure python are
perfectly comparable in performance with c-based solutions.

"Benchmarkers" should focus on other things (even ease-of-use if they want
uWSGI to poorly lose, or on all the other things if they want uWSGI to
easily win :P)

So, stop wasting time measuring already discovered things :)

Wait what? The guy wanted to use Apache to prompt for basic auth,
using django.contrib.auth as a datastore for usernames and passwords -
why is it inappropriate to ask about extending Django's auth on a
django user mailing list? I'm also surprised that you found the answer
the OP needed in 10 seconds (and failed to link the OP to it), given
that there is no direct solution AFAICT.

Far too many people are spending too much time on this mailing list
discussing how to respond to users and what is proper to discuss on
here, and finding the perfect stock answer to tell people to eff off,
rather than actually trying to help them.

OP: This is actually tricky to do. Apache's mod_authn_dbd expects the
passwords to be in certain explicit formats[1], which do not
correspond to how Django's django.contrib.auth package stores the
passwords. As this blog post[2] explains, the issue is that apache
does not take into account the salt used to secure the password
hashes. You could try contacting the author of that post, as he has
written his own way around it.

Cheers

Tom

already try your reccomendation, but still got error.

and i check with other view in the apps, i found out you are right, the bug
is in the render_to_response.

i fix it with this one :
  return render_to_response(template_name,
locals(),context_instance=RequestContext(request))

i miss the RequestContext(request))

This one think which pass all the context processed variable to the
template.

Thanks, and i learn now how to read error message and track it down now..

It solved now..

continue to learning...

something about django mysql database long connection

[oops]

hi,
Now, i am doing a django project, and use models to do all operation
about data in mysql db.

and i think that it would connect to database whenever  do some
operation like 'XXX.objects.all()' , may be it would cast much of
resource on database connection. So i need a connection never being
desconnected.

Does django has this function?  And how to do for it??

thank you

As in, did the tutorial contain any errors / false / inaccurate information?
I would check it myself, but haven't got any spare time at the moment :/ It
looks very cleanly done though, so if someone could confirm the content is
accurate, I'd defo say lets include it in the list.

And I quote:

http://modauthmysql.sourceforge.net/CONFIGURE

AuthMySQLSaltField <> |  | mysql_column_name

  Contains information on the salt field to be used for crypt and aes
  encryption methods.  It can contain one of the following:
<>: password itself is the salt field (use with crypt() only)
: "string" as the salt field
mysql_column_name: the salt is take from the mysql_column_name field in the
  same row as the password

I probably should have told OP how I found the information he needed, and
what steps to take (although the steps I took are explained in the wiki).
I'll ensure to do this next time.

I would also agree that my comments about it being "inappropriate" for this
mailing list were wrong, as although the connection between the question and
Django was loose, it is still a connection nevertheless. My apologies to the
OP on this.

At as best guess (as the question is somewhat broken), are you asking how to

Re: RegistrationForm subclass not showing up

[katstevens]

OK I must have missed something fundamental. I installed v0.8 and
having started all over again, I only made one change - adding an
extra field to the basic RegistrationForm class in registration.forms
- this isn't showing up on my template either!

Looking over my code, I've found it's not just the Registration form
class - when I try altering the default label in e.g.
PasswordResetForm (from django.contrib.auth.forms) the change doesn't
show up in my template either ( {{ form.email.label_tag }} ), it still
displays the default. Is there another mysterious source that django
is getting the form class declaration from instead, or is it just
ignoring my changes for some reason? I'm not getting any errors and
the form itself still works correctly. I haven't changed any of the
default code for PasswordResetForm (urls, views, forms) except that
one label. I can't understand this behaviour at all.

ProgrammingByPermutation is a well-known antipattern (http://

why it works once you have the problem fixed.

Do you mean that you found a link to a ticket about this exact problem

First learn to use django.auth, then if and when it doesn't fit your
needs you'll be able to extend / override it with something more
appropriate.

Re: RegistrationForm subclass not showing up

[Andre Terra]

My guess is that there's another module somewhere in your PYTHONPATH from
which django is importing these forms.

Also, don't edit registration.forms, subclass the form instead.

You can also try {{ form.as_p }} to make sure the problem isn't in the
template.

You can raise an exception somewhere in your code to try to find where in
the python path the module lives. Try something like


def your_view(request):
# ...
# your current code
# ...
from registration import forms
assert False, forms.__file__


Good luck!

Cheers,
André

Would you mind giving us an example of what you mean by setting up the

Re: WindowsError 32

[Peter Murphy]

Domdom,

The first thing to do is Google|Bing|Other Search Engine of your
choice "WindowsError 32". If you had done that, the first link:

http://msdn.microsoft.com/en-us/library/ms681382%28v=vs.85%29.aspx

Would have given you a clue:

ERROR_SHARING_VIOLATION 32 (0x20): The process cannot access the file
because it is being used by another process.

I think the issue is that your code is trying to delete a file when it
is being accessed by something else. Perhaps you forgot to close it
elsewhere?

Best regards,
Peter

speeding up iterating over query set

[Michel30]

Hi all,

I have a basic search function that uses Q objects.
After profiling it I found that the actual (mysql) database query
finishes in fractions of seconds but the iterating after this can take
up to 50 seconds per 10.000 results.

I have been trying to speed it up but I have had not much results..

My query is this one:

   found_entries = model.objects.filter((Q-objects),
obsolete=0).order_by('-version','docid')

So far so good, but then I need a dictionary to retrieve only unique
'documentid's'.

rev_dict = {}

This is the part that hurts:

for d in found_entries:
rev_dict[d.documentid] = d

And then some more sorting and filtering:

filtered_entries = rev_dict.values()
filtered_entries.sort(key=lambda d: d.revisiondate, reverse=True)

Does anyone have some better ideas to achieve this?

Thanks

You could do:

# grab all results
_res =
model.objects.filter((Q-objects),obsolete=0).order_by('-version','docid').values()
# re-map them into (id, obj)
_res = map(lambda x: [x.docid, x], _res)
# wrap in a dict(), which uses index position 0 as the key, and index
position 1 as the value
_res = dict(_res)

Let me know if this give you the results you need.

Just tested the same principle, and it seems to work fine. It uses last
object found as the final choice if dups are found.

Re: speeding up iterating over query set

[Andre Terra]

You seem to be hauling the same data from one side to the other, and I can't
see why.

Try:

MyModel.objects.values_list('id', flat=True)

You can use that to build a dictionary if you add a second field, or using
list comprehensions which I believe are faster than for loops,

dict(MyModel.objects.values_list('id', 'docid'))

but I honestly don't understand what you are trying to do. Maybe if you
share more of the model logic and explain what you are trying to achieve we
can provide you with a way to get there, instead of trying to improve the
way you decided to go about it.


Cheers,
André Terra

Re: RegistrationForm subclass not showing up

[katstevens]

Thank you for your help Andre - I've now worked out what the problem
was. I was editing the wrong copy of the source code (it happens to
everyone at some point!) so no wonder the changes were not
happening... In the end I just created a completely new url path (i.e.
not 'accounts/register') and called registration.views with a
completely new form class in the dictionary parameter.

Here's my final code with the RegistrationForm for reference. In my
project's urls.py I added the following lines:

  import registration.backends.default.urls#
django-registration urls
  from registration.views import register#
django-registration view
  from myapp.newform import MyNewRegistrationForm # my own
customised form

  urlpatterns = patterns('',
url(r'^accounts/', include(registration.backends.default.urls)),
url(r'^accounts/registration/$', register, {'backend':
'registration.backends.default.DefaultBackend', 'form_class':
MyNewRegistrationForm  },
name='registration_register'),

I just copied the code from the original RegistrationForm class to
myapp.newform and added my customised fields, including the
TermsOfService field I originally wanted...

I agree and looked into this, but the backend in Django 1.2 actually
defers to the MySQLdb library.  I couldn't find any references online
that talked about or showed examples for extending a database
backend.  If you know of any, I would really appropriate it if you
could post the link(s).

I searched djangosnippets.org for "proxy sql" and only found
http://djangosnippets.org/snippets/1913/.  That's not exactly what I'm
looking for because it's not hooked into the model's save command.  If
that's not the correct snippet, I would really appreciate it if you
could post the right one.

This is precisely how you're supposed to use it.

While this approach works, it is harder to maintain because any updates (ie.
fixes, new features, etc) that are added to the original RegistrationForm
will never make it to MyNewRegistrationForm. So subclassing and adding just
the TOS logic would be the best approach. It also improves readability for
you, since you'll just have to look to a couple of lines in your
MyNewRegistrationForm as opposed to the whole logic. Considering someone
else maintains django-registration, you can leave that part of the code for
them to worry and just work on your project-specific stuff.

(I'm not sure how clear that paragraph is, so feel free to ask questions!)

I think that you would probably have better luck coming at it from the
other end. That is, in the database itself (stored procedure or
otherwise).

Re: Extending User model with Inheritance - Attribute Error

Thanks for the responses.

How do I use a foreign key, though? In other words, how do I tell my

extra method. 
So I read the docs and I'm wondering if it wouldn't be better to use the 
select_params parameter ?

Re: Extending User model with Inheritance - Attribute Error

[Andre Terra]

Wherever you would reference a user instance, reference UserProfile.user
instead

If you need to find out a profile from request.user, you can use
request.user.get_profile() or the longer UserProfile.objects.get(user_id=
request.user.id)

Re: Extending User model with Inheritance - Attribute Error

[Brent]

I am having trouble with this line of the tutorial: "You need to
register a handler for the signal django.db.models.signals.post_save
on the User model, and, in the handler, if created=True, create the
associated user profile."

It seems I need to edit the User model. I am confused, though, because
I am using the User model included in django.contrib, and I am very
hesitant to edit files that are not in my project directory.

Is this bad design to be using a mix of things I've written on my own,
and things that were already included in Django? (i.e. should I write
everything from scratch?)

Thanks.

Re: Extending User model with Inheritance - Attribute Error

[Andre Terra]

All you have to do is add the following code to your models.py (or any other
module that gets loaded by django, for that matter):

# models.py
from django.db.models import signals

def create_user_profile(sender, instance, created, **kwargs):
 if created:
UserProfile.objects.create(user=instance)

signals.post_save.connect(create_user_profile, sender=User)

(assuming your profile model is called UserProfile, of course).

When django loads models.py, it will call that connect() method which in
turn makes create_user_profile get called every time the sender model (User)
is saved (hence the 'post_save').

More on this at https://docs.djangoproject.com/en/dev/ref/signals/

Pass user.get_profile() as a template variable instead by adding it to the
template context.

Re: Extending User model with Inheritance - Attribute Error

[Brent]

Okay, thanks. This is really helpful.

I am having trouble calling get_profile() from within my profile.html
template, though. Here is my stack trace:

http://dpaste.com/566583/

I tried calling get_profile without the (), which got rid of the
error, but no data showed up.

Re: Extending User model with Inheritance - Attribute Error

So I need to create a custom view? (I can't use an existing view)? I
was hoping to avoid diving into templates until later, after I've
become a little more familiar with the python/html code.

+1. Tsung was maybe the only tool fit for this kind of testing, a while
back, when I was doing some scaling tests.

I had exactly the same thoughts although I'm just intrested (out of
plain curiosity) in how nginx/uwsgi scales with and without the caching
framework.

It would be intresting though to see the difference between the two
stacks.

Of course it does - MySQLdb is the "official" (well, almost) db-api
compliant MySQL binding. Now you asked for "the best way to intercept
the raw SQL sent to the database", and since it's the mysqldb backend
that generates and sends the raw SQL it's still the best place to add
your own code AFAICT.

I'm afraid you'll have to use the code, Luke - at least you have a
working example.

Re: Extending User model with Inheritance - Attribute Error

[Andre Terra]

You could use a context processor, which is basically a function that adds
variables to *every* template that gets called from a properly setup view. I
assume the view you are using does apply context processors, and defining
one is as easy as:

http://stackoverflow.com/questions/3722174/django-template-inheritance-and-context/3731459#3731459

You can try step #3 once you feel confident enough to write views (they are
very simple!)

Adding errors to form after successful validation

[Brian McKeever]

I have a search form that is used by a view to search for results and
then redirect to display them one at a time. If my search doesn't find
any objects matching the criteria, I'd like to display a message
saying so.

It seems natural to add this error to the search form and redisplay it
since it already displays error with the search.

Is there an easy way to do this, or should I be doing something else
because a failed database query is not a form error?

I've been trying to do this:
form.non_field_errors().append(forms.ValidationError("No roblems found
matching that criteria"))
but it doesn't work (non_field_errors() is not well documented).

Re: Adding errors to form after successful validation

[Andre Terra]

I feel your pain, validating forms can be a PITA... Try reading through this
last bit of the form validation docs:

https://docs.djangoproject.com/en/dev/ref/forms/validation/#cleaning-and-validating-fields-that-depend-on-each-other

Ok, so what you want is a queryset of "model" with distinct docid
having the highest version number, sorted by revisiondate ? The
cleanest solution would be to first write the appropriate SQL query,
then find out how to express it using django. FWIW, the raw SQL query
might look like this (MySQL):

mysql> select f1.pk, f1.docid, f1.version, f1.revisiondate from foo f1
where f1.version=(select max(f2.version) from foo f2 where
f2.docid=f1.docid) order by revisiondate desc;
++---+-+--+
| pk | docid | version | revisiondate |
++---+-+--+
|  7 | 3 |   2 | 2000-02-12   |
|  6 | 1 |   2 | 2000-02-11   |
|  5 | 2 |   3 | 2000-02-10   |
++---+-+--+
3 rows in set (0.00 sec)

NB: table definition and date being:

mysql> explain foo;
+--+-+--+-+-++
| Field| Type| Null | Key | Default | Extra  |
+--+-+--+-+-++
| pk   | int(11) | NO   | PRI | NULL| auto_increment |
| docid| int(11) | NO   | | NULL||
| version  | int(11) | NO   | | NULL||
| revisiondate | date| NO   | | NULL||
+--+-+--+-+-++

mysql> select * from foo;
++---+-+--+
| pk | docid | version | revisiondate |
++---+-+--+
|  1 | 1 |   1 | 2000-01-01   |
|  2 | 2 |   1 | 2000-01-02   |
|  3 | 3 |   1 | 2000-01-02   |
|  4 | 2 |   2 | 2000-02-10   |
|  5 | 2 |   3 | 2000-02-10   |
|  6 | 1 |   2 | 2000-02-11   |
|  7 | 3 |   2 | 2000-02-12   |
++---+-+--+
7 rows in set (0.00 sec)


NB: Adding indexes on docid and/or version might help (or damage)
performances, depending on your data set.

Now you just have to learn how to use django's orm F, max and extra.
Or, for a simpler solution (but less portable) solution, use a raw SQL
query to only retrieve distinct pk then a second query to build the
whole queryset, ie:

from django.db import connection

def get_latest_revisions():
cursor = connection.cursor()
cursor.execute("""
SELECT DISTINCT f1.pk  FROM foo as f1
WHERE f1.version=(SELECT max(f2.version) FROM foo f2 WHERE
f2.docid=f1.docid)
""")
ids = [row[0] for row in cursor] # or is it "row['pk']" ???
cursor.close()
return model.objects.filter(pk__in=ids).order_by("-revision_date")

This might possibly be done using
manager.raw(your_sql_here).values_list("pk", flat=True) to build the
pk list, but I have never used RawQuerySets so far and the doc doesn't
tell if RawQuerySet supports values_list so you'll have to try by
yourself.

TransactionTestCase and Fixture Teardown

[David Cramer]

We're currently in the process of converting from unittest (pure) to
Nose, and one of the issues I've noticed while doing this was that the
database wasn't flushing correctly when switching from a
TransactionTestCase to a TestCase. I've been digging through the code
this morning, and I honestly can't even figure out how this would work
in the standard test suite (excluding nose).

I can't imagine this is an actual bug, or that it only came up for
Nose, so I'm hoping someone can explain if there is magic somewhere in
here, and where it is. Otherwise I suppose I can file an awful ticket
to add flush to the teardown step as well (which is what I temporarily
did to move past this problem).

Re: Extending User model with Inheritance - Attribute Error

Re: Adding errors to form after successful validation

[Brian McKeever]

I am now doing my query in the form's clean method, and it errors the
way I want it to. Thank you.

Although, I do feel dirty doing it this way. I feel like I should be
able to append an error to the form in the view.

I can't say exactly why I don't like it, because I don't really know

For our test runner it seems test case [1][2]reordering works in a way
so the TransactionTestCase's go to a bucket after the TestCase's even
when you specify an opposite explicit order. e.g.:

$ ~/django_test/pg83
backends.FkConstraintsTests.test_integrity_checks_on_creation
basic.ModelTest.test_object_creation -v2
[...]
test_object_creation (modeltests.basic.tests.ModelTest) ... ok
test_integrity_checks_on_creation
(regressiontests.backends.tests.FkConstraintsTests) ... ok

--
Ran 2 tests in 1.031s

So there isn't possibility of a TestCase being run after a
TransactionTestCase with our test infrastructure.  I can't say this is
by design or a result of gradual evolution of our test support code.
That's why I'm leaving this note here just in case we want to revisit
this at some point (although I suspect adding a flush at the end of
every test case for MySQL+MyISAM  TransactionTestCase will make it even
slower).

Well, i had my own cribs w.r.t form rendering ...as_p and as_table looked
neanderthal.
However, i moved to uni-form, and am loving it since then.

On the validation, yes, it is a little pesky. But, offlate, i am trying to
*understand* it better and trying to move the logic
to the client. For eg. jquery-validate does bulk of the stuff on client side
- atleast for required fields. So, moving
bulk of the validation to the client helps in avoiding a few http calls.

Re: Django Auth

[Kiril Vladimirov]

You might want to search for something that could *expand* Django Auth to 
the way you like it. But trust me, you don't need anything else.

get all objects that are related to current, reverse look up

[garagefan]

simply put, here's my code

class ContentBlock(Orderable, Displayable):
  location = models.ManyToManyField(ContentBlockLocation, blank=True,
null=True, help_text="list of locations to display content block")
  page = models.ManyToManyField(Page, blank=True, null=True,
help_text="list of pages to display content block")
  height = models.IntegerField(blank=True, null=True)
  width = models.IntegerField(blank=True, null=True)

  def __unicode__(self):
return self.title


class StaticContent(Displayable, RichText):
 content_block =  models.ForeignKey(ContentBlock, blank=True,
null=True)

class StaticContent2(Displayable, RichText):
 content_block =  models.ForeignKey(ContentBlock, blank=True,
null=True)

putting together a template tag that will return all the items
associated with a given ContentBlock, but i would like to do so
without knowing upfront all of the classes that have a foreign key to
ContentBlock as i'll want to be able to add more content types at any
time

Using the mailing list

[Kenneth Gonsalves]

hi,

I think this deserves a thread of it's own. I have started a section on
migrating from other frameworks - since I came from Zope, I have added a
few points there. People from other frameworks/tools please pitch in.

request.method GET or POST

[Venkatraman S]

We have to check for request.method to suitably route the request to the
logic.

Would it be nice if we have something like doGet or doPost(similar to java
servlets) that we have in our views,
so that the request gets automatically routed , and the code is structured
nicely?

So a view would look like:
def funcname(request,itemid,..):
  def doPOST():
#.do things when the request is POST
  def doGET():
#.do things when the request is GET..

Comments? (note that i am not passing request object to individual doPOST or
doGET).

Oops! i did not intend to send this to the list; was planning to suggest to
Shawn of making the clause better to avoid spam.(I should have dozed!)
Apologies again.

Thanks. Actually, i stumbled on this solution due to my use case - i test
all my apps in sqlite3 and then move to other dbs; as it is easy for me to
manage a single db file, and there is no db server overhead . And in this
case, i used the exact same sql excerpt and found that sqlite3 did not
support the math funcs. It was a pretty nifty hack.
