Hi list,
why can I add a record in the admin where the name field is empty,
when the docs say:
"primary_key=True implies blank=False, null=False and unique=True.
Only one primary key is allowed on an object."
My code:
name = models.CharField(maxlength=255, primary_key=True, db_index=True)

blank=False means that a blank field ISN'T allowed.

This means that you cannot add an entry where the name (in my case) is empty.
Argh, sorry... I made a mistake:
primary_key implies blank=False and null=False.
Now it should be correct. :)

Well, I will try add it manually... seems like a bug,
Hello list,
I have a question regarding general database design.
Ok.. which method would you recommend, if you have a table
with a field 'name' which values should be unique in the whole table?
1) use (implicit) id which is automatically added by django, as primary
key and a 'name' field with "un

A point that I missed was the speed. Is method 1) maybe faster than method 2?
I think it could.. because in 1) there are only numbers stored as
primary_key and
not strings (which can be as long as 255 characters).
Speed is one thing.. but is there any other difference between the two methods?

Hi list,
maybe I'm a bit confused (or tired) but
how would you go and cache a view that will *never*
change depending on a request on my application?
If I read the manual right, I have to give a timeout to
all the cache functions that are available. In my case I have
a view that will never change

Hello list!
Is it possible to call functions of the model out of the template?
Sorry, didn't find it in the docs.
Example:
{{ model.function() }}

I must misunderstand something really basic here. Just look:
Template:
{{ movie.genres_title_list }}
models.py:
def genres_title_list(self, separator=', '):
return separator.join([x.title for x in self.genres])
Prints nothing... idea anyone?

Hi list!
I've got a problem:
settings.py:
TEMPLATE_DIRS = ( '/home/kai/Projekte/kaikuehne/templates' )
home.html:
{% extends "/blog/base" %}
I get the following error:
"Template '/blog/base' cannot be extended, because it doesn't exist"
But, the file does exist:
$ ls -l /home/

Hey!
I wanted to select all models, but in random order:
random.shuffle(Obj.objects.all())
This doesn't work, error message:
TypeError: object does not support item assignment
Anyony an idea in how to make it?
(It's for a blogroll, if you wonder where it could be used.)
Greetings :)
Sorry, I got it:
all = Obj.objects.all()
newlist = [x for x in all]
random.shuffle(newlist)
Not that beautiful, but it works. :)

Btw, why is it called maxlength and in newforms
max_length (or the other way around, not sure)?
Shouldn't they be identcal?
