Re: IntegrityError --- NOT NULL constraint failed: books_book.publication_date

Did you perhaps change the schema of the database after you had created it. Eg: added null=True as a constraint after creating the table? If so check the db sheme using: python manage.py sqlall It sounds simple enough. You will have to go into the db shell and update your schema manually. usin

Making functions callable

Hi Guys, I'm running into a problem with django(I guess this would also affect Python in general) where if I create a view eg def view(year=today.year()) The year is never re-evaluated until the server is reloaded/restarted I'm trying to figure out how to make a callable method accessible as a

Re: Making functions callable

For the default value to work as you expect, do this: def view(request, year=None): if year is None: year = today.year() Kwarg defaults are evaluated when the module is interpreted for the first time. John On Mar 26, 2014, at 1:57 PM, Anthony Hawkes wrote: > Hi Guys, > > I'm ru

Re: Making functions callable

Not sure what is going on without seeing the code. But something is None when it should be a string, as the exception is telling you. It's often easiest to try out problem code interactively in Python, and zero in on the problem. John On Mar 26, 2014, at 3:53 PM, Anthony wrote: > Thanks Joh

You might get more responses on the GeoDjango mailing list: geodja...@googlegroups.com I agree the basic libraries probably all work. Are you sure you used OSGeo4w with Python3? OSGeo4w ships 2.7.x, so unless the GDAL and GEOS wrappers also work with Python3 that sounds odd. pypi page makes it lo

Hi Dan, In the shell, did you re-import your Poll model? (>>> from polls.models import Poll) I think you might use a previous version of your model (without the changes), and that's why it doesn't recognize it. I might be wrong though :) Please let me know if it worked. Shai. On Thu, Mar 27
