推荐答案

你有一些django无法使用的外键为...生成唯一的名称。

You have a number of foreign keys which django is unable to generate unique names for.

您可以通过在模型中的foreignkey字段定义中添加related_name参数来帮助您。
例如：

You can help out by adding "related_name" arguments to the foreignkey field definitions in your models. Eg:

content_type = ForeignKey(Topic, related_name='topic_content_type')
