You would order them on the model level or on the view level. In the
model, you can set ordering with the Meta class 'ordering' parameter.
In the view, you would just add .order_by() to your query. Check out

Hey everyone, thanks for looking.
I'm overriding a model save(), and was wondering if there is an
instance of the model being passed in that i can access.
My situation is that i have a title and a slug. I only want to change
the slug when the title is changed. So in my save i want to check:

Thank you, that seems like a clean way to do it. I'm getting a weird
error when overriding init though. When I simply do this:
class Entry(models.Model):
title = models.CharField(max_length=255)
slug = models.SlugField(max_length=255)
body = models.TextField()

Ahh, that'll do it. I'm used to the save() where you call super last.
Works perfect, thanks for the solution!

I think i ran into this issue before. I don't think they define a
max_length anywhere, the restriction is just on the database. Just
increase the field size in the database and you should be good.

Just create a model that stores the url and the expiration time. If
the url is hit past the expiration time, delete it, if it's still
within the time limit, display whatever you want to display. Obviously
this is for a small system, since you would be waiting to delete until

There are a couple ways to do this. You can either override the model
methods like save and init, or you can use signals and tie into the
pre_save, post_save, etc. Signals are here:

If using signals, you will have an instance of the object being s

Seems very odd how you're trying to implement this. Unless your
pseudocode has me confused. Can you give us the view functions too?
Seems like you're trying to use a decorator function on two views. Why
don't you just bail on the decorator, and just check for

You could create a model that references the join table itself.

Yeah, that is going to be my fallback, I was just curious on an actual

Yeah, I realize this now hah. Instead I am now passing request into a
ModelForm for what I need. Basically I have a comment system, and on
each comment post I wanted to run it through Akismet, which required
the IP and User Agent. So I just passed request into my form.save()
method on comment adds.
I just implemented this and it's a hassle. There are heated
discussions about it. I ended up modifying the auth app and completely
eliminating the 'username' field and just using email. Then I modified
the admin app to allow the login, and am basically just completely
overriding both. Good luck!

Sorry for the confusing title. Here is a simple example to illustrate
my question:
class Item(models.Model):
name = models.CharField()
class Manager(models.Model):
item = models.ForeignKey(Item)
On a POST I have the PK of the Item I want to link to a new instance
of the Manager object.
Thanks for the response. I actually will already have the PK, and am
trying to avoid grabbing an instance of the actual item object.

You can go two directions with this. First, you could use a
intermediate model for the many to many join, which would allow you to
specify extra field on the join, in this case the order. Read up on
this here:
http://docs.djangoproject.com/en/dev/topics/db/models/#extra-fields-on-many-to-many-relat
Look into the clear() method on many to many relations.
Calling .clear() before a delete will remove all relations between the
models and allow you to delete the category only. You might be
fighting the django admin on this though, so this would be best
implemented in a custom solution. Not sure if

You're just all around doing it wrong. A ModelForm is used so that you
don't have to individually list all the fields you need, it is based
off the model. What is the code for your Model? And also, I'd reread
the form reference from the start.

Hey everyone, thanks for looking. I couldn't think of a good title for

You could query like this:
Question.objects.filter(answer__isnull=False)
This would give you a set of questions where an answer exists. Setting
it to True would give you a set where answers don't exist.

I'm too lazy to check, but i'm pretty sure the name of your file input
needs to match the name of the form field. Also, try troubleshooting.
Use print statements in the view to see if the file object is being
posted, etc.
