提交表单时不断收到 404 错误和 "No User matches the given query." 消息

Question

我试图让我的用户 post 进入项目页面，但是在提交 post 表单时我收到 404 和消息 "No User matches the given query." 我也不确定是否我的 form_valid 部分正确。

我希望我的用户能够在他们拥有的不同项目页面上创建 post，并且每个 post 都与正确的项目相关。

任何帮助和示例代码将不胜感激！

您将表单发布到 /new_project/，但您的 urls.py 中不存在该表单。你可能是说 /create_project/.

提交表单时不断收到 404 错误和 "No User matches the given query." 消息

Keep getting 404 error and "No User matches the given query." message on form submission
