Hello list,
through trial and error I discovered that it isn't required to pass the
foreign key form field post data to the constructor of an inline form set.
Django will fill it in automatically by looking at the primary key of the
'instance=' given. So I figured I might as well exclude the hidden FK field
from the form:
class Group(models.Model):
interest = models.CharField(max_length=100)
class Member(models.Model):
name = models.CharField(max_length=100)
group = models.ForeignKey(Group)
MemberFormSet = inlineformset_factory(Group, Member, exclude=('group',))
The 'exclude=' instruction is ignored and the form is printed the same as
without 'exclude=('group',)'. This is odd, since the FKs aren't strictly
required in the form set: if you pass post data *with* foreign key fields
to the constructor MemberFormSet(), Django will use it for validation, but
if you don't pass them, it's fine too, because Django will simply use the
instance to fill them in automatically.
So, how can I exclude my 'group' foreign keys from the printed form set?
Thank you and cheers, glts
