将多个模型添加到inlineformset_factory

Question

I have a model like below.

class Content(SimpleModel):
    title = models.CharField(max_length=255)
    body = models.TextField()
    slug = models.SlugField(max_length=50)    

    def __unicode__(self):
        return self.title


class MediumStuff(models.Model):
    meta_value = models.TextField()
    meta_key = models.SlugField('Field Name', max_length=50, blank=True)
    content = models.ForeignKey(Content)

    def __unicode__(self):
        return self.slug


class SmallStuff(models.Model):
    text = models.CharField(max_length=60, blank=True, null=True)
    content = models.ForeignKey(Content)

What I wanna do is to create formset for content that has inline forms for models of MediumStuff and SmallStuff using inlineformset_factory()

I referred to Django Documentation , but they have a example of how to work with foreign key model.

ContentFormSet = inlineformset_factory(Content, [MediumStuff, SmallStuff])

nor

ContentFormSet = inlineformset_factory(Content, (MediumStuff, SmallStuff))

didn't work.

Since it is possible to add multiple inlines to admin, I believe this can be done :)

Do you have any suggestion / any resources or tips? Or possibly tell me where I should look at to see how admin handles multiple inlines?

Answer 1

Just create one inline for each related model:

MediumStuffInline = inlineformset_factory(Content, MediumStuff)

SmallStuffInline = inlineformset_factory(Content, SmallStuff)

Take a look how admin does. Each inline is handled by a subclass of InlineModelAdmin [1]. The inline itself is created on the get_formset() method [2].

Check out the documentation on how to use more that one formset in a view [3][4]
