Question

如何将在单元测试中创建的Django Oscar篮子附加到request对象上？

# views.py

from django.contrib.auth.mixins import LoginRequiredMixin

from rest_framework.response import Response
from rest_framework.views import APIView

class BasketAPIAddView(LoginRequiredMixin, APIView):
    """
    Update basket via REST API.
    """
    def delete(self, request, format=None):
        #
        # cannot access `request.basket` here
        #
        return Response({})

# tests.py

from django.contrib.auth import get_user_model
from django.urls import reverse
from oscar.test.factories import create_basket
from rest_framework.test import APITestCase

User = get_user_model()

class BasketAPITests(APITestCase):
    """
    Basket view test cases.
    """
    def test_remove_basket_line(self):
        basket = create_basket()
        basket.owner = User.objects.create_user('user', password='pass')
        basket.save()

        self.client.login(username='user', password='password')
        self.client.delete(reverse('delete-basket'))

Answer 1

您可以执行以下操作：

Traceback (most recent call last):
  File "example-json.py", line 11, in <module>
    json_dict = json.loads(data)
  File "/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/json/__init__.py", line 348, in loads
    return _default_decoder.decode(s)
  File "/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/json/decoder.py", line 337, in decode
    obj, end = self.raw_decode(s, idx=_w(s, 0).end())
  File "/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/json/decoder.py", line 355, in raw_decode
    raise JSONDecodeError("Expecting value", s, err.value) from None
json.decoder.JSONDecodeError: Expecting value: line 4 column 14 (char 62)

关键是使用请求工厂并随心所欲地添加对象（添加所需内容）。

Answer 2

对于常规请求，oscar.apps.basket.middleware.BasketMiddleware将篮子添加到请求中，因此可能需要检查测试项目正在使用的settings.MIDDLEWARE或APITestCase提供的客户端正在运行中间件。

如果您正在开发API，则可能还需要研究django-oscar-api处理会话管理和中间件的方式。
