异常值：Django基于类的View对象没有属性＆＃39; campaignId＆＃39;

Question

我被困在这几个小时;我可能遗漏了一些简单的东西，但我不确定。非常感谢任何帮助。

我最近将Django项目的数据库从MongoDB更改为Neo4J。在迁移过程中，我正在修改一些视图，URL等。

我看到的追溯：

Exception Value: 'TweetListView' object has no attribute 'campaignId'

以下是完整的追溯和相关代码：https://gist.github.com/joefusaro/820270c1ff0999d3d3fd

如果您发布了完整的回溯，那将会更容易，这将显示错误发生的确切位置。

然而，它可能发生在你的视图的get_object方法中，其第三行应该是：

self.object = GetTwitterPostsForCampaign(self.kwargs['campaignId'])
