URL Rewrite problem in lighttpd

[Jon Jenkins]

I have a django site deployed on lighttpd running on FreeBSD, using FastCGI.

When I specify a URL, for example, http://www.site.com/blog, the debug
program will say 404 and claim that I passed the URL mysite.fcgi/blog.
However, if I put a trailing slash on the URL, everything works fine.

My URL rewrite looks like so:

url.rewrite-once += (
"^(/.*)$" => "/mysite.fcgi$1",
)

To make matters even more confusing, I have a second site running in
the exact same way which is unaffected by this problem. Any help with
this would be appreciated.

Re: Why can't erase this model object? "AssertionError: Question object can't be deleted because its id attribute is set to None."

[JohnA]

Is your code really that simple - I mean get the queryset and
immediately try to delete something out of it?  If so, maybe it's time
to step through the delete in the debugger.  Querysets are lazy but I
assume that referencing an item in the queryset kike you do will cause
the actual data to get feteched.  Maybe the problem is trying to
delete something directly out of the queryset, or maybe you're somehow
deleting the same record twice, or maybe django is somehow getting
confused while performing the operation.

In the Django shell I do

quests = Question.objects.all()
quests[579].delete()

Why does the objects.all() invocation add this id=None crud to quests
list?

[JohnA]

How are you finding these objects?  That might point to the answer.

Probably the likeliest explanation is that you are creating the
objects but not saving them.

Re: Can't make 404.html template to be used. Keep getting Apache 500 Internal Server Error instead.

Last line below says error is that there is no handler500.  I thought
a missing web page for some URL was a 404 error so I'm not sure why
this error is popping up.

That makes perfect sense but then why do these zombie id=None objects
show up?
*WHERE* are they living if not in the database?  Does the Django shell
somehow have a secondary storage area for this zombie id=None object
stuff I can delete somehow?

your Category model did you drop the category table and then syncdb?

Re: Having Headache With LoginForm

[coded kid]

Thanks for the help bro.

How can I make the form verify users name and password before login
in. So that if the user wants to login in with wrong data, the form
will tell the user to login in with the correct data. Any idea?

Can this code be put in the views.py?
def get_user(self, user_id):
try:
return User.objects.get(pk=user_id)
except User.DoesNotExist:
return None
So that it can verify users data before they loggin in?

Re: How to use a DB table for choices=tuples in ChoiceField?

[Bill Beal]

It looks like the Pythonic way is to create the list in
models.py and invoke it from forms.py.

Sorry about the heterogeneous names--some of
them match the document the requirements were
extracted from and others are more meaningful
to me.  The former were picked because we'll
need a requirements cross-reference and they'll
be easier to match up with the requirements.
And the dashes in place of spaces--most of the
code examples I see here are almost unreadable
because of leading spaces disappearing.
I saw one example of replacing all but the last
leading space with '-', and it was more readable.

Regards

Re: Why can't erase this model object? "AssertionError: Question object can't be deleted because its id attribute is set to None."

Models are representations of rows in a database.
Deleting a model instance implies removing a row from a database.
Model instances have an id attribute which denotes their row in the database.
Models whose id is None don't exist in the database, and so it is
nonsense to delete them - they don't exist.

While it has been asked a trillion times already, let me say TRY UT
YOURSELF. Sometimes even doing on console such as vim is not bad.
However if you are working on a huge project an IDE can help you.
Pycharm is very good. The problem is still very new but its
development. Maturity is outstanding. I love its database auto
complete. But version control is still e

At University I've learned various techniques for model-driven

Check out Dia which has a Python script interface and I seem to remember 
someone doing a script to create Django models from the ER or UML 
diagrams. It is a while since I looked at it so I might be leading you 
astray.


Good luck

Can any of these sorts of—or for that matter, any sort of—model-driven
development techniques be used for Django?

Yes -- the request object [1] holds that sort of information; in
particular, you're looking for the HttpRequest.get_host() call [2].
