Ok - I take that back - I don't get the same behaviour. True - the SQL doesn't get a default clause. This is by design. Default values are created python-side when the python object is created. However, I have no difficulty creating an object without specifying a responded= clause. Can you elaborate on the error message you are receiving? Side note - When validating your report, I got an SQL error too - but the problem wasn't with the default clause - it was with the SQL cursor. If the SQL cursor gets messed up because of a previous error, you might be getting misleading error reports.

hi Scott,
this is great! however, I'm having another problem, let me put it
straight:
I'm building a generic purpose bookmark app, which could be used to:
1. bookmark models in 'bookmarkable_list' of a django site
2. bookmark external urls
I built the 'bookmarkable_list' from settings.py in the following way:
== settings.py ==
BOOKMARKABLE_APP_MODEL_LIST = ['aiyo.content', 'aiyo.product',
'comments.comment', 'comments.freecomment']
== bookmark.py ==
from agv.settings import BOOKMARKABLE_APP_MODEL_LIST
q = Q()
for app_model in BOOKMARKABLE_APP_MODEL_LIST:
app_label, model = app_model.split('.')
q = q | (Q(app_label__exact=app_label) & Q(model__exact=model))
BOOKMARKABLE_DJANGO_CONTENT_TYPE_ID_LIST = [str(d['id']) for d in
ContentType.objects.filter(q).values('id')]
any advice to make it better?
Regards,
- Eric

PEP 8 is the more-or-less canonical reference, since it is what is used in the standard Python libraries (see [1]). Django tends to follow the guidelines in there, in particular, indenting is done with four spaces (not tabs). So that is almost certainly your problem in this case.

Simple Model Syntax Errors
This is my second time going through the http://www.djangoproject.com/documentation/tutorial1/;>Django
tutorials. The first time I ran through the whole process on my
dreamhost server without any errors. This time I'm using the local
development server on my computer (Mac OS X v10.4.6 / Python 2.4)
In http://www.djangoproject.com/documentation/tutorial1/;>tutorial
one, you are to define a simple Poll model as well as a Choice
model. Everything works fine (able to access and save records via the
API) until I try to add a __str__() method to represent the model.
from django.db import models
class Poll(models.Model):
question = models.CharField(maxlength=200)
pub_date = models.DateTimeField('Date Published')
def __str__(self):
return self.question
Once I add this simple representation and start the Python Interactive
Prompt I get syntax errors (prooject name is webmules):
>>> from webmules.polls.models import Poll, Choice
Traceback (most recent call last):
File "", line 1, in ?
File "/Users/swm/Sites/webmules/../webmules/polls/models.py", line 8
def __str__(self):
^
SyntaxError: invalid syntax
>>>
What's odd is if I remove the method and add an inner Admin() class,
like:
from django.db import models
class Poll(models.Model):
question = models.CharField(maxlength=200)
pub_date = models.DateTimeField('Date Published')
class Admin:
pass
I get syntax errors when I start the development server:
Django version 0.95 (post-magic-removal), using settings
'webmules.settings'
Development server is running at http://127.0.0.1:8000/
Quit the server with CONTROL-C.

If I don't have the __str__() method the API works great, if I don't
define the inner Admin class my development server starts without any
problems. It seems like anything I add to my models breaks everything
else. Has anyone ever seen anything like that?
Apologies for the long message, just wanted to be thorough. Thanks in
advance.

Not a problem, Eric, glad to be of help.
You could also do this:
ContentType.objects.filter(app_label__exact='aiyo',

which is more concise and may treat the query optimizer in your database

Default value for boolean field
Hi, I'm working up a simple, one-off web-based survey (so pls don't knock me for not normalizing).

Re: Symlink Error? Please help.
I would suggest that, before you attempt to setup Django with Apache/FCGI, you try the built-in development server. It's faster to get up and running with it and you will know quickly if anything is wrong with your installation. With the Apache/FCGI setup, it would be difficult to track down any problems as there would be many more potential points of failure. It looks like you have Django installed. You should start following the main tutorials now. The best way to confirm the installation for you is to see if you are able to create a simple project following the tutorials and then do the built-in "python manage.py runserver". You don't need to cd to the python path you mentioned in order to run this command. You run it from your project's root directory. Good luck! --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: Symlink Error? Please help.
Thanks Rajesh, you were right on! The 'pwd' was the culprit and now I know for future reference. Thank you so much. One more UNIX question. According to the documentation to http://code.djangoproject.com/wiki/OsxFcgi;>Setup Django with Apache 1.3 and FCGI I can check to see if Django is running correctly by running 'python2.4 manage.py runserver' from the command prompt. To do this I need to 'cd' into: /Library/Frameworks/Python.framework/Versions/2.4/lib/python2.4/site-packages/django/conf/project_template Is there anyway I can setup an alias so I can run this command from the main prompt without having to traverse into that directory? Thanks in advance!! So now that the symlink is setup, how can I check to see if Django is properly installed?

Re: Symlink Error? Please help.
Open a terminal and check which version of Python you have (python -V). Chances are that you are running 2.3. The instructions you tried above assume 2.4. You can get 2.4 for Mac from here: http://www.python.org/download/mac/ I am running Django with Python installed from the Universal Installer Build on Tiger with no problems. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Thanks, that's great! I'll start using that.
I have another, smaller related problem with urls.
I can't do this
(r'^blogs/([_A-Za-z0-9-]+)/', include('bloghost.blog.urls')),
because then the captured bit after blogs doesn't go anywhere.
I have to do this:
..
(r'^blogs/([_A-Za-z0-9-]+)/', 'frontpage')),
(r'^blogs/([_A-Za-z0-9-]+)/feed/', 'rss')),
...
Which is fine really, more of an itch than anything else, but it'd be
nice to do it the Right Way(TM).
Thanks,
Frankie.
