Hello,
I have a question for all you django wizards. I want to use different forms
for managing a model in Django's admin. I thought it's common problem, but I
cannot find a good solution even after reading through google, stackoverflow
and django's source code. (My apologies if this is a often asked newbie
question).
For example, I have a model like this:
# users/models.py
...
REG_STATUS_TYPE = (
( 'queued', 'Queued' ),
( 'sent', 'Sent' ),
( 'accepted', 'Accepted' ),
( 'declined', 'Declined' ),
( 'blocked', 'Blocked' ),
)
class RegistrationQueue(models.Model):
user = models.ForeignKey(User)
created = models.DateTimeField(default=datetime.datetime.now,
editable=False)
status = models.CharField(max_length=10, choices=REG_STATUS_TYPE,
default='queued')
accepted = models.DateTimeField(editable=False, null=True)
...
# users/admin.py
...
class RegistrationViewForm(models.ModelForm):
class Meta:
model = RegistrationQueue
class RegistrationAddForm(models.ModelForm):
class Meta:
model = User
class RegistrationQueueAdmin(admin.ModelAdmin):
add_form = RegistrationAddForm
view_form = RegistrationViewForm
def get_form(self, request, obj=None, **kwargs):
defaults = {}
if obj is None:
defaults.update({
'form': self.add_form,
})
else:
defaults.update({
'form': self.view_form
})
defaults.update(kwargs)
return super(RegistrationAdmin, self).get_form(request, obj,
**defaults)
admin.site.register(RegistrationQueue, RegistrationQueueAdmin)
What I'm trying to do is simple really. When creating a new
RegistrationQueue entry, I would like Django's admin to use a form derived
from the User model (which would let me create a temporary user, and then I
can take some of the information from that and other things to automatically
create a RegistrationQueue entry).
However, when listing or changing the RegistrationQueue, I would like to use
a form derived from the RegistrationQueue model.
So, as you can see above, I tried to replace ModelAdmin's get_form method
with a custom one that just checks the incoming obj variable. If it's set to
None, I know it's trying a create a new entry. Otherwise, it's something
else.
The problem is that the admin always uses the form derived from the
RegistrationQueue, and never the User. Whenever I click to add a
RegistrationQueue, I get a form with fields belonging to the
RegistrationQueue model.
Please tell me what I'm doing wrong. Thank you very much in advance.
