Django中的内联格式 - 删除某些字段 [英] Inline formset in Django - removing certain fields
问题描述
a)将 MyModel
中的某些字段排除在外, / p>
b)显示一些字段 MyModel
,但阻止它们被编辑。
我尝试使用下面的代码,使用 values()
,以便将查询集过滤到我想要返回的那些值。不过,这个失败了。
任何人有任何想法?
class PointTransactionFormset(BaseInlineFormSet):
def get_queryset(self):
qs = super(PointTransactionFormset,self).get_queryset()
qs = qs.filter(description =促销反馈)
qs = qs.values('description','points_type')#这不工作
return qs
class PointTransactionInline(admin.TabularInline):
model = PointTransaction
#formset = points_formset()
#formset = inlineformset_factory(UserProfile,PointTransaction)
formset = PointTransactionFormset
文档中似乎没有说明的一件事是,您可以在模型表单的参数中包含一个表单。所以,例如,假设你有一个人模型,你可以通过这样做在模型表单中使用它
PersonFormSet = inlineformset_factory(User,Person,form = PersonForm,extra = 6)
表单验证,排除等等,并在工厂复制它。
I need to create an inline formset which
a) excludes some fields from MyModel
being displayed altogether
b) displays some some fields MyModel
but prevents them from being editable.
I tried using the code below, using values()
in order to filter the query set to just those values I wanted returned. However, this failed.
Anybody with any idea?
class PointTransactionFormset(BaseInlineFormSet):
def get_queryset(self):
qs = super(PointTransactionFormset, self).get_queryset()
qs = qs.filter(description="promotion feedback")
qs = qs.values('description','points_type') # this does not work
return qs
class PointTransactionInline(admin.TabularInline):
model = PointTransaction
#formset = points_formset()
#formset = inlineformset_factory(UserProfile,PointTransaction)
formset = PointTransactionFormset
One thing that doesn't seem to be said in the documentation is that you can include a form inside your parameters for model formsets. So, for instance, let's say you have a person modelform, you can use it in a model formset by doing this
PersonFormSet = inlineformset_factory(User, Person, form=PersonForm, extra=6)
This allows you to do all the form validation, excludes, etc on a modelform level and have the factory replicate it.
