我将 travis 集成到我使用 postgres 的项目中，但是当我尝试测试时，我陷入了一个未知的错误，即

 $ python manage.py test
Traceback (most recent call last):

    return TEST_DATABASE_PREFIX + self.connection.settings_dict['NAME']
TypeError: must be str, not NoneType
The command "python manage.py test" exited with 1.

我在.travis.yml文件中使用了如下的 postgres 格式

 services:
  - mongodb
  - postgresql

 before_script:
  - sleep 15
  - psql -c 'create database myapp_test;' -U postgres

我将要做的？

来自Django 的源代码，TEST_DATABASE_PREFIX在第 12 行定义。

TEST_DATABASE_PREFIX = 'test_'

这意味着self.connection.settings_dict['NAME']没有

从Django 的文档中，您需要在设置文件中设置测试数据库，例如

DATABASES = {
'default': {
    'ENGINE': 'django.db.backends.postgresql',
    'USER': 'mydatabaseuser',
    'NAME': 'mydatabase',
    'TEST': {
        'NAME': 'mytestdatabase',   <--- YOU NEED CONFIG HERE!
    },
},
