I am trying to render an inlineformset but the "extra" attribute seems to be ignored. Consider the following models:
class Foo_model(models.Model):
fooName = models.CharField(max_length=LIL_STRING)
bars = models.ForeignKey("Bar_model")
class Bar_model(models.Model):
barName = models.CharField(max_length=LIL_STRING)
forms:
class Foo_form(ModelForm):
class Meta:
model = Foo_model
class Bar_form(ModelForm):
class Meta:
model = Bar_model
Bar_formset = inlineformset_factory(Foo_model,Bar_model,formset=Bar_form,extra=23)
view:
def ViewFoo(request, model_id=False):
if model_id:
model = Foo_model.objects.get(pk=model_id)
else:
model = Foo_model()
form = Foo_form(instance=model)
formset = Bar_formset(instance=model)
return render_to_response('form.html', {'form' : form, 'formset' : formset }, context_instance=RequestContext(request))
and template:
<html>
<form method="POST" action="">
{% csrf_token %}
<div>
{{ form }}
{{ formset }}
</div>
<input class="button" type="submit" value="Submit"/>
</form>
</html>
This only shows one instance of Bar_form, when it ought to show 23 ("extra=23"). Any ideas what I'm doing wrong?
Thanks
Update:
It turns out that part of the problem is that all of my model classes inherit from the same base class. If I make them just inherit from models.Model, then the problem goes away (though other problems rear their ugly heads). I still want them to inherit from a single class, so my original question remains.
Update Update:
Making my models' base class abstract:
class BaseClass(models.Model):
class Meta:
abstract = True
Seems to do the trick. I can now have ForeignKeys and ManyToManyFields between my classes.
Since the foreign key exists in the
Foomodel, you'll need to create aFooFormSet(otherwise, logically, it doesn't make sense as to what the form would contain).
