Question

我正在尝试向表单添加内联formset。这是重现错误的最小代码：

models.py

class Festival(Model):
    desc = TextField(max_length=1000)

class FestivalAddress(Model):
    festival = ForeignKey(Festival, related_name="addresses")
    name = CharField(max_length="50")

urls.py

urlpatterns = patterns('',
    url('^add/$', FestivalCreateView.as_view(), name='festival_add'), 
)

views.py

class FestivalCreateView(CreateView):
    model = Festival
    form_class = FestivalForm

    #Add FestivalAddressFormset to context here

forms.py

class FestivalAddressForm(ModelForm):
    class Meta:
        model = FestivalAddress

class FestivalForm(ModelForm):
    class Meta:
        model = Festival

FestivalAddressFormSet = inlineformset_factory(FestivalForm, FestivalAddress, form=FestivalAddressForm, extra=2)

抛出AttributeError：'ModelFormOptions'对象没有属性'get_parent_list'。我有点难过，因为我正在按照here on SO给出的解决方案。

编辑：我删除了FestivalCreateView对formset的使用，因为无论是否出现错误都会发生错误。

Answer 1

看起来我对inlineformset_factory的调用不正确。根据{{3}}，第一个参数应该是模型，而不是表格。

Answer 2

应该是： FestivalAddressFormSet = inlineformset_factory(Festival, FestivalAddress, form=FestivalAddressForm, extra=2)

Django内联formset错误
