Hi,
I am fairly new to django, so if I missed a piece of documentation
that would describe what I want to do please feel free to redirect me,
I may have missed it in my search.
I have a pretty simple problem that I cannot quite get my head around.
I have a Many To Many relationship between UserProfile and Group (a
custom group class, not the django auth one) that represents which
real life groups my users are members of. The users should be able to
join some of the groups all by themselves, while for others an admin
must do the group join operation for them.
I am currently having a problem with the view that allows the users to
join groups. It uses a ModelForm with a custom filter on the groups
the user can select, like so:
class UserProfileForm(ModelForm):
groups = forms.ModelMultipleChoiceField(queryset=Group.objects.filter
(open_to_all__exact='True'), required=False)
class Meta:
model = UserProfile
exclude = ('member_id', 'member_status', 'year_of_entry',
'course_at_entry', 'user')
The problem is that when I save this form, the group memberships of
the items that were excluded by the filter get deleted.
How can I avoid this?
My attempt was to do this before the form.save() call:
form.cleaned_data['groups'] = form.cleaned_data['groups'] + list
(fixed_memberships)
but cleaned_data['groups'] seems to be a queryset and I have not yet
understood how to modify this queryset to include items from another
queryset or a list.
Any hints would be greatly appreciated!
TIA,
Daniel
