将自定义create方法添加到模型后，许多测试开始失败。当仅执行“阶段1”时一切都很好，但是添加了“阶段2”后：通过GL的API创建GitLab项目，很多测试失败了。
模型是这样定义的：
class CarModelViewSet(viewsets.ModelViewSet):
queryset = CarModel.objects.all()
serializer_class = CarModelSerializer
lookup_field = 'model_id'
def create(self, request, *args, **kwargs):
## stage 1:
serializer = self.get_serializer(data=request.data)
serializer.is_valid(raise_exception=True)
serializer.save()
## stage 2:
proj_name = str(serializer.data['model_id']) + str(serializer.data['name']).replace(' ', '_')
proj_desc = str(serializer.data['name']) + ' Project'
req_headers = {
'content-type': 'application/json',
'PRIVATE-TOKEN': settings.REPOSITORY_TOKEN
}
req_body = {
"name": proj_name,
"namespace_id": 10,
"description": proj_desc
}
repository_url = 'https://gitlab.example.com/api/v4/projects/'
res = requests.post(repository_url, json.dumps(req_body), headers=req_headers)
response = res.json()
response_msg = {
"message": "Model added to database. Project created in GitLab.",
"id": response["id"], ########### KeyError: 'id'
"name": response["name"],
"name_with_namespace": response["name_with_namespace"],
"ssh_url_to_repo": response["ssh_url_to_repo"],
"http_url_to_repo": response["http_url_to_repo"],
"web_url": response["web_url"]
}
return Response(response_msg, status=status.HTTP_201_CREATED)
示例测试：
class CarModelTests(TestCase):
def setUp(self):
self.client = APIClient()
def test_create_correct_car_model(self):
"""Test creating valid Car Model instance."""
payload = {
"model_id": "12/34/5678-9",
"name": "Test Model",
"active": True
}
res = self.client.post(CAR_MODELS_URL, payload)
models = CarModel.objects.all()
serializer = CarModelSerializer(models, many=True)
self.assertEqual(res.status_code, status.HTTP_201_CREATED)
print(json.dumps(serializer.data))
self.assertEqual("Model added to database. Project created in GitLab.",
json.dumps(serializer.data[0]["message"]))
测试报告指出带有"id": response["id"]的那一行是失败的（不确定测试运行是否在这一点上终止并且没有报告其他运行，或者仅仅是此条目失败了。）
手动测试工作正常，模型已在数据库中创建，新项目出现在GitLab中。
我应该怎么做才能克服这种失败？

添加了“第2阶段”：通过GL的API创建GitLab项目后，许多测试失败了。
测试已经创建了一个项目和项目ID；任何进一步的测试都将失败，因为该项目已经存在。
要检查它是否存在，请执行GET /users/:user_id/projects或任何类似的请求，并检查要在响应中创建的项目的名称（或其他名称）。
看起来像这样：

我还建议您使用python-gitlab。它具有许多使这些事情变得容易的功能。
答案 1 :(得分：0)
您的问题在于以下行：
res = requests.post(repository_url, json.dumps(req_body), headers=req_headers)
将其更改为：
res = requests.post(repository_url, json=req_body, headers=req_headers)
请注意，您不必编码请求JSON数据
