使用Django表单创建内联formset时出现这个奇怪的错误。我究竟做错了什么？

my models.py looks like this:

我的models.py看起来像这样:

class Member(models.Model):
    name = models.CharField(max_length=255)
    occupation = models.CharField(max_length=255)

class FamilyMember(models.Model):
    name = models.CharField(max_length=255)
    relation = models.CharField(max_length=255)
    member = models.ForeignKey(Member)

Now, I am trying to create an inline form for family members inside the members form. To do that, I am using inlineformset_factory:

现在,我正在尝试为成员表单中的家庭成员创建内联表单。为此,我使用inlineformset_factory:

from django import forms from myapp.models import * from django.forms.models import inlineformset_factory

来自django的导入表单来自myapp.models import *来自django.forms.models import inlineformset_factory

class MemberForm(forms.ModelForm):
    class Meta:
        model = Member
        fields = [
            'name', 'occupation',
        ]

FamilyMemberFormSet = inlineformset_factory(Member, FamilyMember)

When I run the server, I get a weird error :

当我运行服务器时,我得到一个奇怪的错误:

"Calling modelformset_factory without defining 'fields' or "
django.core.exceptions.ImproperlyConfigured: Calling >modelformset_factory without defining 'fields' or 'exclude' explicitly is prohibited.

What am I doing wrong? Thanks.

我究竟做错了什么?谢谢。

2 个解决方案

#1

I'm not sure but I think you forgot to pass the form to inlineformset_factory:

我不确定,但我认为您忘记将表单传递给inlineformset_factory:

FamilyMemberFormSet = inlineformset_factory(Member, FamilyMember, form=MemberForm)

Or you should specify what fields should be included/excluded using either fields parameter or exclude.

或者,您应使用fields参数或exclude指定应包含/排除的字段。

See some examples in Django doc about inlineformset_factory.

请参阅Django doc中有关inlineformset_factory的一些示例。

here you are:

这个给你:

FamilyMemberFormSet = inlineformset_factory(Member, FamilyMember, fields =['name', 'occupation',])
