Question

在我的应用程序中，我有一些模型，分别是ModelAdmins和ModelForms ......

class Group(models.Model):
    pass

class Department(models.Model):
    groups = models.ManyToMany(Group, through='MyModel')

class MyModel(models.Model):
    department = models.ForeignKey(
        'department.Department',
        related_name="group_memberships",
    )
    group = models.ForeignKey(
        'group.Group',
        related_name="department_memberships",
    )

class MyModelInlineFormset(BaseInlineFormSet):
    def clean(self):
        # some working formset validation here
        pass

class MyModelInline(admin.StackedInline):
    model = MyModel
    extra = 1
    formset = MyModelInlineFormset

class DepartmentAdmin(ModelAdmin):
    inlines = (MyModelInline,)

我已经在formset级别进行了验证，但现在我想为每个内联设置一些验证。为此，我添加了以下内容：

class MyModelForm(forms.ModelForm):
    class Meta:
        model = MyModel

    def clean(self):
        cleaned_data = super(GroupDepartmentMembershipForm, self).clean()
        delete_checked = cleaned_data.get('DELETE')
        department = cleaned_data.get('department')
        group = cleaned_data.get('group')
        if delete_checked:
            if not group.departments.exclude(pk__exact=department.pk):
                raise forms.ValidationError('orphan group!')
        return cleaned_data

class MyModelInline(admin.StackedInline):
    model = MyModel
    extra = 1
    formset = MyModelInlineFormset
    form = MyModelForm

看起来没问题，调试器上的行为似乎没问题，ValidationError已创建，但它永远不会到达浏览器，执行的验证没有任何效果。

我发现当我在FormSet级别验证时它可以正常工作。但它在Form级别上并不相同。有没有想过修复内联表单验证？
