Python 3.x 如何将ChoiceField选项传递给formset？

这个名字很好用，但我可以用同样的方法计算出如何传递选择列表。这些字段是空白的。在调试中，选项显示为正确设置

forms.py

class MatchSheets(forms.Form):
    """ Match sheets """
    name = forms.CharField()
    propertyuser = forms.ChoiceField(choices=(), required=False)


SheetSet = formset_factory(
    MatchSheets,
    extra=0
)

    sheets = PropSheetNames.objects.filter(owner=request.user,
                                           sponsoruser=sponsoru_id)
    props = SponsorsUsers.objects.filter(owner=request.user,
                                           id=sponsoru_id).all()

    initial_set = []
    choiceset = (((prop.id), (prop.alias)) for prop in props[0].properties_user.all())

    for sh in sheets:
        initial_set.append(
            {'name': sh.name,
             'propertyuser.choices': choiceset}
        )

    form = SheetSet(request.POST or None, initial=initial_set)

视图.py

class MatchSheets(forms.Form):
    """ Match sheets """
    name = forms.CharField()
    propertyuser = forms.ChoiceField(choices=(), required=False)


SheetSet = formset_factory(
    MatchSheets,
    extra=0
)

    sheets = PropSheetNames.objects.filter(owner=request.user,
                                           sponsoruser=sponsoru_id)
    props = SponsorsUsers.objects.filter(owner=request.user,
                                           id=sponsoru_id).all()

    initial_set = []
    choiceset = (((prop.id), (prop.alias)) for prop in props[0].properties_user.all())

    for sh in sheets:
        initial_set.append(
            {'name': sh.name,
             'propertyuser.choices': choiceset}
        )

    form = SheetSet(request.POST or None, initial=initial_set)

我知道有人会指出，对于整个事情来说，使用

modelformset\u工厂

，或者对于

propertyuser

，使用

modelselect

可以做得更好，但我在这两个方面都遇到了问题，手动操作给了我更多的灵活性

首先，这是错误的（更正）：

然后将此添加到下面的

form=

for f in form:
        f.fields['propertyuser'].choices = choiceset

能够更进一步，将选项也默认为name字段的值：

    initial_set = []
    nameset = [prop.alias for prop in props[0].properties_user.all()]
    choiceset = [((prop.alias), (prop.alias)) for prop in props[0].properties_user.all()]
    choiceset.append(('', '----'))

然后

    for f in form:
        f.fields['propertyuser'].choices = choiceset
        if f.initial['name'] is not None and f.initial['name'] in nameset:
            f.fields['propertyuser'].initial = f.initial['name']

现在，用户只需要处理不匹配的对，就可以了。这就是我被挤出使用模型选项的原因，至少在我的能力水平上是这样
