TypeError at /post/3/comment/ 'dict' 对象不可调用请求方法：POST 请求 URL： http://localhost:8000/post/3/comment/ Django 版本：2.1.7 异常类型：TypeError 异常值： “dict”对象不可调用

Answer 1

错误告诉您究竟出了什么问题。self.kwargs是一个字典，但你正在调用它。你可能的意思是：data = Post.objects.get(id=self.kwargs['pk'])

Answer 2

你也可以试试这个：form.instance.post = Post.objects.get(id=self.kwargs.get('pk'))
