无法创建Django测试数据库

django-testing django python

Joren · 技术社区 · 6 年前

我有一个有数百个迁移的项目。当我尝试运行测试时,它会给我stacktrace:

./manage.py test
Creating test database for alias 'default'...
Traceback (most recent call last):
  File "/project/lib/python3.5/site-packages/django/db/backends/utils.py", line 62, in execute

    return Database.Cursor.execute(self, query)
sqlite3.OperationalError: near "USING": syntax error

The above exception was the direct cause of the following exception:

仅凭这个,我似乎无法找出原因(可能是某个地方的迁移)。当我尝试使用Postgres数据库运行相同的命令时,我会得到一个错误

因为我使用了价值观 N 在整个项目中,这也没有多大帮助。如何找到导致这些错误的迁移?

您可以添加 --verbosity 属于 -v 选项在运行测试时,这会增加测试输出的详细程度:

python manage.py test -v 2

或

python manage.py test --verbosity=2

第2级应该显示所有迁移。第3级甚至显示了更多的细节,但我认为这不会在你的案例中增加太多。

这将向您显示导致该问题的迁移。
