我已经覆盖AdminModel'sModelForm以使字段可从's 管理员更改表单中User食用和保存。Person

class Person(models.Model):
    user = models.OneToOneField(User)
    #and also some char, text fields

    @property
    def name(self):
        return self.user.first_name
    @name.setter
    def name(self, value):
        self.user.first_name = value

    #and by analogy surname and email properties


class PersonForm(ModelForm):
    class Meta:
        model = Person

    name = forms.CharField(max_length=100, required=False)
    surname = forms.CharField(max_length=100, required=False)
    email = forms.EmailField(required=False)

    def save(self, commit=True):
        instance = super(PersonForm, self).save(commit)  
        user = instance.user
        user.first_name = self.cleaned_data['name']
        user.last_name = self.cleaned_data['surname']
        user.email = self.cleaned_data['email']
        user.save()
        return instance

class PersonAdmin(admin.ModelAdmin):
    fields = ['name', 'surname', 'email', 'and_others']

    form = PersonForm

admin.site.register(Person, PersonAdmin)

但是我正在努力编写一个检查 save() 方法的测试：

def test_form_saves_values_to_instance_user_on_save(self):
    """
    test that, form saves name, surname, email values to corresponding User
    when commiting form
    """
    user = User.objects.get(username='admin')
    person = Person.objects.get(user=user)
    personform = PersonForm(instance=person, data={'name': 'has_changed'})

    # if uncommented raisesValueError: The Person could not be changed
    # because the data didn't validate.
    # personform.save()

    self.assertEquals("has_changed", User.objects.get(pk=user.pk).first_name)

更新测试

更新解决方案。原来我没有填写请求的不可见字段“用户”。排除使表格有效并通过测试。

管理员.py

class PersonForm(ModelForm):
    class Meta:
        model = Person
        exclude = ('user',)
# ...

测试.py

def test_form_saves_values_to_instance_user_on_save(self):
    """
    test that, form saves name, surname, email values to corresponding User
    when commiting form
    """

    person = Person.objects.get(user__username='admin')
    personform = PersonForm(instance=person, data={'name': 'has_changed'})

    if personform.is_valid():
        person = personform.save()
        self.assertEquals(User.objects.get(pk=person.user.pk).first_name, "has_changed")
    else:
        self.fail("personform not valid")

我认为您还需要user从表单中排除该字段

class PersonForm(ModelForm):
    class Meta:
        model = Person
        exclude = ('user',)
    ...

将新数据作为字典传递给您的表单（作为第一个位置参数或作为data），并断言personform.cleaned_data['name']等于User.objects.get(pk=user.pk).username. 然后对surname和做同样的事情email。

请注意，first_namealast_name为max_length30，而表单字段的 amax_length为 100。
