Question

好的，有些人请向我解释为什么会出现这个错误

profile.html

<%= @user.username %>

profile.controller

class InterfaceController < ApplicationController
    #before_action :authenticate_user!

    def profile
        @user = User.find(params[:user_id])
    end
end

我已经阅读了堆栈溢出的每个帖子都有相同的错误但是没有帮助我。我真的很感激帮助和解释。

Answer 1

profile GET    /profile(.:format)                          interface#profile

这与您的控制器无法正确匹配。您应该更改routes.rb文件，以便将:user_id传递给控制器。您生成的路线应如下所示：

profile GET    /profile/:user_id(.:format)                          interface#profile

您可以使用resource或在routes文件中显式添加参数来实现此目的。请参阅resources routing和bound parameters。我推荐前者。

如果您正在尝试创建用户的个人资料，我还建议将其保留在相同的控制器和资源路由命名空间中，而不是创建一个新的“接口”控制器。
