Hi All,
I've been struggling with this issue for a few days now. In IRC, clong
got me the closest I've been to a solution, but things are still
erroring out. I have two inital models:
class Person( models.Model ):
name = models.CharField (maxlength = 100)
user = models.ForeignKey (
User,
verbose_name="Associated admin user",
null = True,
blank = True
)
role = models.ManyToManyField ('Role')
def get_people_in_role( roles ):
list = []
for x in Person.objects.all ():
for role in x.role.get_query_set():
if role.name in roles:
list.insert (0,x)
return list
def __str__( self ):
return self.name
class Meta:
ordering = ('name',)
verbose_name_plural = 'people'
class Admin:
pass
class Role( models.Model ):
name = models.CharField (maxlength = 20)
def __str__( self ):
return self.name
class Meta:
ordering = ('name',)
class Admin:
pass
The Roles will be stuff like "pastors" and "acolytes" etc etc. (The
associated admin user thing is thanks to the code at 23 excuses).
I'd like to use this in, for example, this class:
from people.models import Person, Role
class Sermon( models.Model ):
title = models.CharField (maxlength = 200)
day = models.CharField (maxlength = 200)
date = models.DateField ()
slug = models.SlugField (prepopulate_from = ('day', 'date'))
passage = models.CharField (maxlength = 200)
body = models.TextField ()
preacher = models.ForeignKey (
Person,
limit_choices_to = { 'role__pk': Role.objects.filter(name =
'Pastor')}
)
def __str__( self ):
return self.title
class Admin:
list_display = ('title', 'day', 'date')
search_fields = ('title', 'day', 'body', 'preacher')
list_filter = ('date', 'day')
clong gave me that limit_choices_to, but it still errors out.
Basically, I'd like to define roles, and then limit the people choices
to those people who "play" that role. For example, sermons can only be
associated with Pastors, services also to Pastors, flowers to Flower
Bearers, and so on and so forth. There are probably 10 or so different
roles.
All this is for the "admin" interface, by the way. I'd love some help
(any help!) on doing this successfully. Praetorian found this message:
http://groups.google.com/group/django-users/browse_thread/
thread/6460e63e0e6c88d8/
and it may well be related, but I'm not sure. Even so, I'd love a
workaround until the proper solution is implemented.
Thanks for your time!
