小编use*_*235的帖子

我正在创建一个示例,以了解有关使用SessionWizard的内联表单集的更多信息.最后,我想集成动态表单集,以便在提交之前通过模板添加和删除单个表单.但是,当第二种形式中没有数据时,它不能像常规ModelForm那样进行验证.

        return name

urls.py

test_forms = [['parent', ParentForm],['child', ChildFormSet]]

urlpatterns = patterns('example.views',
    url(r'^$', TestWizard.as_view(test_forms)),
)

forms.py

class ParentForm(ModelForm):
    class Meta:
        model = Parent

class ChildForm(ModelForm):
    class Meta:
        model = Child
        exclude = ('parent',)

ChildFormSet = inlineformset_factory(Parent, Child, extra=1)

class TestWizard(SessionWizardView):
