Django Rest Framework单元测试

Question

我在那儿，所以我尝试使用DRF单元测试，而.post出现了一些问题

我认为这与我使用的外键有关，但是我找不到任何好的示例。

串行：

class UserSerializer(serializers.ModelSerializer):
    class Meta:
        model = get_user_model()
        fields = ('password', 'id', 'username', 'email')
        write_only_fields = ('password',)

    def restore_object(self, attrs, instance=None):
        # call set_password on user object. Without this
        # the password will be stored in plain text.
        user = super(UserSerializer, self).restore_object(attrs, instance)
        user.set_password(attrs['password'])
        return user

class MultimediaSerializer(serializers.ModelSerializer):
    class Meta:
        model = Multimedia


class SpaceSerializer(serializers.ModelSerializer):
    user = UserSerializer()
    avatar = serializers.HyperlinkedRelatedField(view_name='multimedia-detail')
    contents = serializers.HyperlinkedRelatedField(
        many=True, view_name='multimedia-detail'
    )
    api_key = serializers.SerializerMethodField('get_api_token')

    class Meta:
        model = Space

楷模：

class UserProfile(models.Model):
    user = models.OneToOneField(settings.AUTH_USER_MODEL)
    avatar = models.ForeignKey(
        'core.Multimedia', blank=True, null=True,
        related_name='user_profiles_avatares'
    )
    language = models.ForeignKey('core.Language', blank=True, null=True)
    birth_date = models.DateTimeField(blank=True, null=True)
    country = CountryField(blank=True, default='PT')
    about_me = models.TextField(blank=True, default='')
    facebook_token = models.TextField(blank=True, default='')
    space_themed_motivation = models.TextField(blank=True, default='')
    created_on = models.DateTimeField(auto_now_add=True)
    updated_on = models.DateTimeField(auto_now=True)
    last_login_on = models.DateTimeField(auto_now=True)


class Space(UserProfile):
    degree = models.CharField(max_length=200, blank=True)
    galleries = models.ManyToManyField('core.Gallery', blank=True, null=True)
    contents = models.ManyToManyField('core.Multimedia', blank=True, null=True)

因此，我在此端点中使用的身体数据是：

def test_register_space(self):
    url = reverse('space-list')
    data = {
      "user": {
        "username": "blaya2", 
        "email": "blaya2@example.com",
        "password": "blayablaya" 
      },
      "avatar": "http://localhost:8000/api/v1/multimedia/1/",
      "contents": [
        "http://localhost:8000/api/v1/multimedia/1/",
        "http://localhost:8000/api/v1/multimedia/2/" 
      ],
      "language": "PT",
      "birth_date": "2014-10-30T10:59:22Z",
      "country": "PT",
      "about_me": "Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum",
      "facebook_token": "CAALDUez5gFsBAHGZCsi1BOeKwc",
      "space_themed_motivation": "Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum",
      "created_on": "2014-10-30T10:59:30.556Z",
      "updated_on": "2014-10-30T11:30:00.717Z",
      "last_login_on": "2014-10-30T11:30:00.717Z",
      "degree": "Mestrado" 
    }

    response = self.client.post(url, data, format='json')
    print response.data

然后我使用response = self.client.post(url, data, content_type='application/json')调用它response = self.client.post(url, data, content_type='application/json')我也尝试了json.dumps（），但是没有运气。 我总是收到400状态代码。

当我print response.data我得到：

{'language': [u"Invalid pk 'PT' - object does not exist."], 'user': [{u'non_field_errors': [u'Invalid data']}], 'contents': [u'Invalid hyperlink - object does not exist.'], 'avatar': [u'Invalid hyperlink - object does not exist.']}

我了解我必须具有指向的链接，但是我不知道使此工作正常的语法。

有谁知道我该怎么做？

Answer 1

400状态代码表示您的json中有一些不良数据。 也许您缺少必填字段等。您应该尝试打印出response.content 。 如果一切正常，它将向您显示对象。 否则，它将显示错误消息，该消息应比400更有用。

Answer 2

在测试中，您必须使用json.dumps序列化JSON数据。

response = self.client.post(url, json.dumps(data), content_type='application/json')

如果仍然无法解决问题，则应检查响应中包含的内容。 它应该为您提供更具体的错误消息，以帮助您解决问题。
