> I've only found how to make default choice for my choice field by
reading this ticket.
Hmm, you might want to know then that the ticket description is wrong.
Setting a default of 0 gives that as the default: 0. Not the value
associated with the 1st element in the choices list. For example with this
model:
{{{
#!python
class Thingy(models.Model):
ttype = models.CharField(max_length=20, choices=(('abc', 'ABC!'),
('123', '123!')), default=0)
}}}
you get a Thingy with ttype value 0, not 'abc', when you create a Thingy
and don't specify ttype:
{{{
>>> from ttt.models import Thingy
>>> newt = Thingy.objects.create()
>>> newt.ttype
0
>>>
}}}
There is nothing special about specifying the default value for a field
that has choices specified. You need to specify just that: the default
value you want the field to have, just as you do for fields without
choices. choices are orthoganal and used for form presentation purposes
only; there is no consideration of the choices value when the default
value is recorded or used.
