Answer 1

將其從@user更改爲@current_user的after_token_authentication。你authenticate_user!調用需要@current_user被設置爲每點擊這裏：where is devise implementation of "authenticate_user!" method?

Answer 2

此消息僅表示在您之前的某個過濾器中呈現了模板或發生了重定向。在你的情況下，after_token_authentication過濾器重定向到contractor_list_galleries_path，這結束了過濾器之前的鏈。此消息不是錯誤，只是顯示告訴你重定向發生在過濾器之前而不是實際的行爲。
