Question

我正在尝试将Django_bb添加为现有django项目中的应用程序，当我点击论坛中的很多链接时，我收到此错误...

Failed lookup for key [forum_settings] in u"[{'False': False, 'None': None, 'True': True}, {}, {}, {u'moderator': True, u'topics': [<Topic: askjdlaskjdlsakdj>], u'posts': 0, u'categories': [<Category: Languages>, <Category: Other>], u'forum': <Forum: English>}]"

这就是说forum_settings模块没有导入？导入语句在视图中没有问题，因此我不确定丢失的内容或在哪里，我不知道如何跟踪它，任何人都有任何想法？

Answer 1

由于未将上下文处理器添加到主django设置文件中，因此未传递上下文。我通过添加...来修复它。

TEMPLATE_CONTEXT_PROCESSORS = (
    ...
    'djangobb_forum.context_processors.forum_settings',

）

Django找不到密钥[keyname]
