运行测试时导入两次 [英] import twice when run test

问题描述

我在我的tests.py中有这个代码：

 从模型导入* 
  

并且在models.py中我有一个信号处理程序并将其注册到

  post_save.connect（post_save_note，sender =注）
  

我运行测试与 ./ manage.py test main

我发现信号处理程序已注册两次并执行两次，
，我发现这是因为模型被导入两次。

不能从模型导入* $ c>在测试代码中？
我应该怎么做？

解决方案

你需要确保你的模型总是以相同的方式导入。 p>

所以例如，如果你在 example1 / tests.py 中：

 从模型导入* 
  

和另一个package example2 / views.py ：

  from example1.models import ModelA 
  

那么你会遇到你遇到的问题。解决方案是一致的，只能使用一个或另一个。

i have this code in my tests.py:

from models import *

and in the models.py I have a signal handler and register it with

post_save.connect( post_save_note, sender=Note )

and when i run test with ./manage.py test main

I found the signal handler was registered twice and executed twice, and I found it's because the models was imported twice.

can't i put from models import * in the test code? what should i do?

解决方案

You need to make sure your models are always imported the same way.

So for example, if you have in example1/tests.py:

from models import *

and in another package example2/views.py:

from example1.models import ModelA

then you'll have the problem you are experiencing. The solution is to be consistent and use only one or the other.
