Then I run python manage.py shell, and there Video.objects.all(), there are all 25 objects (counted them using len and by iterating them with for ...
I have an issue where, when I log in to the Django admin site, I get a template syntax error in /Library/Python/2.6/site-packages/django/template/debug.py in render_node, line 81. I can't find out how to solve this as it is part of Django, I didn't write the code and I have no idea how it works. This did work fine up until a few days a...

A while back I made a Model class. I made several ModelForms for it and it worked beautifully. I recently had to add another optional (blank=True, null=True) field to it so we can store some relationship data between Users. It's essentially a referral system. The problem is adding this new field has meant the referral field shows up wh...
I have a dozen or so permission lookups on views that make sure users have the right permissions to do something on the system (ie make sure they're in the right group, if they can edit their profile, if they're group administrators, etc). A check might look like this: from django.contrib.auth.decorators import user_passes_test test_c...

Please follow this link to see which middleware that I use. I call this middleware with: get_current_user() This worked fine till now. But now I experi...
Short description: given a queryset myQueryset, how do I select max("myfield") without actually retrieving all rows and doing max in python? The best I can think of is max([r["myfield"] for r in myQueryset.values("myfield")]), which isn't very good if there are millions of rows. Long description: Say I have two models in my Django app,...
I have an import script which runs a series of commands to get things from one Postgres DB to another, both running the same Django codebase. For the most part, it uses ./manage.py loaddata to copy over, but some objects require additional processing and I use Django's objects.create() method in a custom script to copy the data. When doi...
I don't know if this is expected behavior or not, but if I create a project with a single model with an ImageField field and upload a photo with the filename "árvórés", the uploaded file is saved with an incomprehensible filename(ascii, I presume). As a direct result, that photo becomes impossible to retrieve from the site. Is this norm...
Hi there, I'm not sure if decorators are the best way to do this, but I've removed the idea of using context processors and I'm not sure if a middleware is what I'd like. My situation is as follows: We process sales and other data daily. Every month, we close the month off just like any other business. We do this on paper, but I would ...

heya, I have a Django project, that has a "Address" model. This is used in several places - by a "User Profile" model, by a "Hospital" model, by an "Insitution" model etc. I'm using Django's generic relations to allow each of these objects to create a foreign-key to Address. However, this seems to cause some weirdness in the Django Ad...
