在 Django 中测试特定模型
是否可以有一组模型仅用于测试目的？我的想法是，我编写了一个应用程序，其中包含一些辅助抽象模型 HelperBase。现在我想提供一些继承它的模型来测试它，例如 DerivedTest1、DerivedTest2。然而，我真的不希望这些测试模型最终出现在生产数据库中。我只想在测试数据库中构建他们的表。是否可能，如果可以-如何做到？我已经尝试在 tests.py 文件中创建模型，但这似乎不起作用。
Is it possible to have a set of models just for testing purposes? The idea is that I've written an app that contains some helper abstract model HelperBase. Now I'd like to provide some models that would inherit from it in order to test it, say DerivedTest1, DerivedTest2. However I wouldn't really like those test models to appear in the production database in the end. I just want their tables to be constructed in the test database. Is it possible and if so - how to do it? I've already tried creating models in the tests.py file but this doesn't seem to work.

您可以尝试创建一个仅在开发服务器上使用的全新应用程序。
例如，如果您的应用程序名为
myapp，您将调用您的测试应用程序myapp_test。然后在
myapp_test的models.py中，您将from myapp import models，然后在其中对模型进行子类化。然后，在您的
settings.py中，您可以在部署到生产服务器时尝试并记住注释掉INSTALLED_APPS中的myapp_test应用程序。或者，您可以使用local_settings.py方法仅将myapp_test包含在测试计算机上的INSTALLED_APPS中。You could try creating a whole new app that you only use on your development server.
E.g., if your app is called
myappyou would call your testing appmyapp_test.Then in
myapp_test'smodels.pyyou wouldfrom myapp import modelsand then subclass your models in there.Then in your
settings.pyyou either just try and remember to comment out themyapp_testapplication fromINSTALLED_APPSwhen deploying to your production server. Or you can use thelocal_settings.pymethodology to only have themyapp_testincluded inINSTALLED_APPSon your test machine.
