Django内联formset错误 [英] Django inline formset error
问题描述
我正在尝试向表单添加内联表单。以下是复制错误的最小代码:
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
$ $ $ $ $ $ $ $ $ $
$ c
$ b #Add FestivalAddressFormset到上下文
forms.py
class FestivalAddressForm(ModelForm):
class Meta:
model = FestivalAddress
class FestivalForm(ModelForm):
class Meta:
model = Festiv al
FestivalAddressFormSet = inlineformset_factory(FestivalForm,FestivalAddress,form = FestivalAddressForm,extra = 2)
这将抛出AttributeError:'ModelFormOptions'对象没有属性'get_parent_list'。我有点困惑,因为我正在遵循 编辑:我删除了FestivalCreateView的表单集合的使用,因为错误发生在或没有它 看起来我对inlineformset_factory的调用不正确。根据文档,第一个参数应该是一个模型,而不是一个表单。 I'm trying to add an inline formset to a form. Here's the minimal code for reproducing the error: models.py urls.py views.py forms.py This throws AttributeError: 'ModelFormOptions' object has no attribute 'get_parent_list'. I'm a bit stumped, as I'm following the solution given here on SO. Edit: I removed FestivalCreateView's usage of the formset because the error occurs with or without it. It looks like my call to inlineformset_factory was incorrect. According to the docs, the first argument should be a model, not a form. 这篇关于Django内联formset错误的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持IT屋!
