Question

我试图让我的用户发布到项目页面上，但是在提交帖子表单时，我得到了404并且消息“没有用户匹配给定的查询”。我也不确定我的form_valid部分是否正确。

我希望我的用户能够在他们拥有的不同项目页面上发布帖子，并且每个帖子都与正确的项目相关。

非常感谢任何帮助和示例代码！

class UserProjectForm(forms.ModelForm):

    class Meta:

#form to create a post

您将表单发布到/ new_project /，但是在urls.py中不存在。你可能意味着/ create_project /.

继续收到404错误并且“没有用户匹配给定的查询”。表单提交上的消息
