Good afternoon.
下午好。
I'm testing api based on django-rest-framework using pytest. As far as I knew at the beginning of the test, py.test creates a duplicate database with the prefix test_. But the pattern during writing tests noticed that it is not receiving data from the database. That is a duplicate of this supposedly empty. A simple example:
我正在使用pytest测试基于django rest-framework的api。就我在测试开始时所知道的，py。test使用前缀test_创建一个重复的数据库。但是编写测试时的模式注意到它没有从数据库接收数据。这是这个假设为空的东西的复制品。一个简单的例子:
@pytest.mark.django_db
def test_db():
qs = Category.objects.get(id=4)
assert qs['id'] = 4
Its returns this error below, but in a database, object with id=4 exists.
它返回下面的错误，但是在数据库中，id=4的对象存在。
> assert qs['id'] == 4
E assert [] == 4
I am new to testing, may miss something, help please.
我是新手，可能会错过一些东西，请帮忙。

Like Daniel commented, test DB is initially empty. You can add any data you want for testing by using one of two methods:
正如Daniel所说，测试DB最初是空的。您可以使用以下两种方法之一添加您想要测试的任何数据:
- Django Fixtures - You can add data using a JSON file just like initial data.
- Django fixture——可以使用JSON文件添加数据，就像初始数据一样。
- Mock data using a library such as django dynamic fixture during run time.
- 在运行时使用库(如django动态夹具)的模拟数据。
These are your best bets.
这是你最好的选择。
