I'm trying to make a decorator that checks if a user is staff and
redirects to the login page if not logged in or returns a 403 for
logged in users that aren't staff.
I found permission_required_with_403 (http://www.djangosnippets.org/

I'm building a library system and have models Member, Loan and

A member can borrow up to 6 books at a time, so my form contains 7
individual forms (1 loan and 6 loan items), I need to get the
One of the fields in an inline formset has a foreign key to another

I'm building a library system, the models are loans, loan items and

I have a model that's related to itself, the instance names are not
unique. I want to order by full path so the result is like a list of
directory paths
a

a/b/c

b/e
It's obvious why order_with_respect_to it doesn't work (although a
mention of this exception in the docs would be good
The problem ("Foo bar with this None and None already exists.") only
happens when I use a ModelForm and choose to specify the field details
myself. Here is an example

I want the same add new functionality as model foreign key select
boxes in admin, there the select widget is passed through
django.contrib.admin.widgets.RelatedFieldWidgetWrapper to add the
additional html (image, links etc).
The __init__.py takes the admin_site instance, I want this
functionality
request.user.message_set.create(message="Your playlist was added
successfully.")
The docs (http://docs.djangoproject.com/en/dev/topics/auth/#messages)

Familiarise yourself with the python command line ('manage.py shell')
and the querying docs, shouldn't take long.

that's not relevant.
Hope this helps

I have a ModelForm form, I want to use a different widget than the
default but when I do I lose the help_text.
The first thing I tried was modelName.fieldName.help_text but it

fields, I can't even get a list of the model's fie

Say there are 10 records, I want records 3 & 4 in descending order.
q1 = ModelName.objects.order_by('id').filter(id__gte=3)[:2] # gives
the records I want but in ascending order
q2 = ModelName.objects.order_by('-id').filter(id__gte=3)[:2] # gives
the last 2 records (9 & 10) in correct order
q3 =
