Django Rest Framework路由器寄存器不工作

Question

我使用django rest框架来生成一个api。其中我有两个模型，关联视图和序列化程序。它们是beers和{}。beersapi端点按预期工作，但是每当我试图访问pours端点时，都会出现以下错误：

Could not resolve URL for hyperlinked relationship using view name "pours-detail". You may have failed to include the related model in your API, or incorrectly configured the 'lookup_field' attribute on this field.

我不太清楚我做错了什么，有人能指出错误吗？在
