TL;DR: I need a some kind of formset for formsets.
I have two different models related to one buisness-entity, and I need to make a form to edit both models like a one form. And I need to create a lot of such forms on the one page like djngo inline formset does.
Now I have the following thing:
class Parent(models.Model):
name = models.Charfield()
class FirstChild(models.Model):
name = models.Charfield()
e_id = models.IntegerField()
parent = models.ForeignKey(Parent)
class FirstChildForm(django.forms.ModelForm):
class Meta:
model = Child
fields = ('name', 'e_id', 'parent')
widgets = {'parent': forms.TextInput}
And I render a lot of them usiing inline formsets:
formset_class = inlineformset_factory(Parent, FirstChild,
form=FirstChildForm, extra=1)
But now I have to add second child model and a form for it, and still render it like an one inline form, bit make it form actually edit two models. Like this:
class SecondChild(models.Model):
name = models.Charfield()
e_id = models.IntegerField()
parent = models.ForeignKey(Parent)
class SecondChildForm(django.forms.ModelForm):
class Meta:
model = Child
fields = ('name', 'e_id', 'parent')
widgets = {'parent': forms.TextInput}
formset_class = inlineformset_factory(models=[Parent, FirstChild],
forms=[FirstChildForm, SecondChildForm],
extra=1)
As far as I understand, Django formsets cannot work with multiple models right now.
So which way should I choose to implement this behaviour and do not broke all django conceptions? I cannot use some extra libraries so I have to implement everything by myself and I use django 1.6 if it is important.
