Я пишу тесты для моего Django Rest Framework API.
Я застрял на тесте «удалить».
Мой тест на «создание» работает нормально.
Вот мой тестовый код:
import json
from django.urls import reverse
from rest_framework import status
from rest_framework.test import APITestCase
from users.models import CustomUser
from lists.models import List, Item
class ListAPITest(APITestCase):
@classmethod
def setUp(self):
self.data = {'name': 'Test list', 'description':'A description', 'item': [
{'name': 'Item 1 Name', 'description': 'Item 1 description', 'order': 1},
{'name': 'Item 2 Name', 'description': 'Item 2 description', 'order': 2},
{'name': 'Item 3 Name', 'description': 'Item 3 description', 'order': 3},
{'name': 'Item 4 Name', 'description': 'Item 4 description', 'order': 4},
{'name': 'Item 5 Name', 'description': 'Item 5 description', 'order': 5},
{'name': 'Item 6 Name', 'description': 'Item 6 description', 'order': 6},
{'name': 'Item 7 Name', 'description': 'Item 7 description', 'order': 7},
{'name': 'Item 8 Name', 'description': 'Item 8 description', 'order': 8},
{'name': 'Item 9 Name', 'description': 'Item 9 description', 'order': 9},
{'name': 'Item 10 Name', 'description': 'Item 10 description', 'order': 10}
]}
# 'lists' is the app_name set in endpoints.py
# 'Lists' is the base_name set for the list route in endpoints.py
# '-list' seems to be something baked into the api
self.url = reverse('lists:Lists-list')
def test_create_list_authenticated(self):
"""
Ensure we can create a new list object.
"""
user = CustomUser.objects.create(email='person@example.com', username='Test user', email_verified=True)
self.client.force_authenticate(user=user)
response = self.client.post(self.url, self.data, format='json')
list_id = json.loads(response.content)['id']
# the request should succeed
self.assertEqual(response.status_code, status.HTTP_201_CREATED)
# there should now be 1 List in the database
self.assertEqual(List.objects.count(), 1)
def test_delete_list_by_owner(self):
"""
delete list should succeed if user created list
"""
user = CustomUser.objects.create(email='person@example.com', username='Test user', email_verified=True)
new_list = List.objects.create(name='Test list', description='A description', created_by=user, created_by_username=user.username)
self.client.force_authenticate(user=user)
response = self.client.delete(self.url + '/' + str(new_list.id))
self.assertEqual(response.status_code, status.HTTP_204_NO_CONTENT)
Вместо ожидаемого статуса 204 я вижу:
AssertionError: 405 != 204
405. Метод не разрешен.
Вот мое определение модели:
class List(models.Model):
"""Models for lists
"""
id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False)
created_by = models.ForeignKey(USER, on_delete=models.CASCADE, related_name='list_created_by_id')
created_by_username = models.CharField(max_length=255) # this shold be OK given that the list will be deleted if the created_by_id user is deleted
created_at = models.DateTimeField(auto_now_add=True)
parent_item = models.ForeignKey('Item', on_delete=models.SET_NULL, null=True, related_name='parent_item')
modified_by = models.ForeignKey(USER, on_delete=models.SET_NULL, null=True,
related_name='list_modified_by')
modified_at = models.DateTimeField(auto_now_add=True)
name = models.CharField(max_length=255)
description = models.CharField(max_length=5000, blank=True, default='')
is_public = models.BooleanField(default=False)
def __str__(self):
return self.name
Вот мой набор:
class ListViewSet(FlexFieldsModelViewSet):
"""
ViewSet for lists.
"""
permission_classes = [IsOwnerOrReadOnly, HasVerifiedEmail]
model = List
serializer_class = ListSerializer
permit_list_expands = ['item']
pagination_class = LimitOffsetPagination
def get_queryset(self):
# unauthenticated user can only view public lists
queryset = List.objects.filter(is_public=True)
# authenticated user can view public lists and lists the user created
# listset in query parameters can be additional filter
if self.request.user.is_authenticated:
listset = self.request.query_params.get('listset', None)
if listset == 'my-lists':
queryset = List.objects.filter(created_by=self.request.user)
elif listset == 'public-lists':
queryset = List.objects.filter(is_public=True)
else:
queryset = List.objects.filter(
Q(created_by=self.request.user) |
Q(is_public=True)
)
# allow filter by URL parameter created_by
created_by = self.request.query_params.get('created_by', None)
if created_by is not None:
queryset = queryset.filter(created_by=created_by)
# return only lists that have no parent item
toplevel = self.request.query_params.get('toplevel')
if toplevel is not None:
queryset = queryset.filter(parent_item=None)
return queryset.order_by('name')
Я прочитал документы , но мне не удалось найти, как настроить запрос на удаление.
Я также пробовал это:
kwargs = {'pk': new_list.id}
response = self.client.delete(self.url, **kwargs)
Это дает мне ошибку:
AssertionError: Expected view ListViewSet to be called with a URL keyword argument named "pk". Fix your URL conf, or set the `.lookup_field` attribute on the view correctly.
Удаление в моем приложении работает нормально через API в моем интерфейсе React.
Я знаю, это сбивает с толку, что мой объект называется List ... но трудно придумать другое имя, потому что это то, что это такое!
Спасибо за любые идеи, которые мне здесь не хватает!
