Question

我有一个似乎没有加载灯具的TestCase。

我正在构建测试数据库时看到此错误：

No fixtures found.  
.............................................Problem installing fixture '/Users/Bryan/work/CNPROG/forum/fixtures/forum_fixtures.json': Traceback (most recent call last):

class UserProfileTestCases(TestCase):  
    """These are tests to verify that refactoring of UserProfile is correct"""  
    fixtures = ['forum_fixtures.json'] # apparently this needs to be in fixtures/ directory.  
    def setUp(self):  
        self.client = Client()  
        if self.client.login(username='DickCheney', password='test'):   
            print "client.login DickCheney successful";    
        else:   
            print "client.login FAILED"

由于某种原因，装置没有加载。

夹具位于：
forum / fixtures / forum_fixtures.json

如何输出夹具未加载的原因？

Traceback建议在这里发生一些事情：
在record_ask_event中输入文件“/Users/Bryan/work/CNPROG/forum/models.py”，第656行

但我无法想象为什么会影响灯具的加载。当我查看代码时，通过post_save事件调用record_ask_events 我能够成功manage.py loaddata forum_fixtures所以我相信我正确地设置了它们。

Answer 1

使用此命令运行更详细的测试： python manage.py test --verbosity = 2

我通过重新安排灯具的顺序来解决这个问题。

如果您有Related对象，则需要确保在fixture中首先列出具有最多关联的对象（例如auth_user），因为在保存期间可能会调用相关对象。

Django v1.2只查找名为'initial_data'的灯具。没有一次搜索'forum_fixtures.json'

我将灯具名称更改为'initial_data.json'，现在可以正常工作。

Answer 2

您需要更改post_save信号处理程序以尊重'raw'kwarg。如果您使用它做了类似的事情，那么您的信号处理程序在夹具加载期间不会导致错误：

@receiver(post_save, sender=MyModel, dispatch_uid='MyModelUID')
def handler(sender, *args, **kwargs):
    if kwargs.get('raw'):
        return
    else:
        ...stuff

Answer 3

我遇到了这个问题。我的应用程序包含在我的设置文件中的INSTALLED_APPS元组中。所以根据django docs，它应该在app目录下的fixtures目录中搜索我放在TestCase类的'fixtures'属性中的任何文件名。不行。不想命名我的夹具'initial_data.json'，因为我只想在运行单元测试时使用它。
