如果单击用户名,则无法显示用户的详细信息

unable to show details of a user if their username is clicked on

我正在制作 Twitter 克隆。在我的推文索引中,我目前在他们的推文旁边有发推文的人的用户名。我想要它,所以当您单击名称时,它会转到他们的个人资料页面。但是,当我单击任何用户名时,它会将您带到当前用户配置文件。有什么办法可以解决这个问题?谢谢

<h1>TWEETS</h1>

<h1>Profile of <%= @user.username  %> </h1>

您在列表中引用了错误的用户。

  # change this, your @user is defined in controller as current_user
  <%= link_to tweet.user.username, user_path(@user) %>

  # to
  <%= link_to tweet.user.username, user_path(tweet.user) %>

旁注:如果您为 current_user

设置了应用程序级别的辅助方法,则您也不需要设置 @user
