Question

我正在尝试允许管理员用户删除此应用程序中的其他用户，但点击删除链接会重定向到所选用户的页面。

user_controller.rb

class UsersController < ApplicationController
    before_filter :authenticate,    :only => [:index, :edit, :update, :destroy] 
    before_filter :correct_user,    :only => [:edit, :update]
    before_filter :admin_user,      :only => :destroy

    def destroy
        User.find(params[:id]).destroy
        flash[:success] = "User destroyed."
        redirect_to users_path
    end

  private

    def authenticate
        deny_access unless signed_in?
    end

    def correct_user
        @user = User.find(params[:id])
        redirect_to(root_path) unless current_user?(@user)
    end

    def admin_user
        redirect_to(root_path) unless current_user.admin?
    end
end

application.html.erb

<!DOCTYPE html>
<html>
<head>
    <title><%= title %></title>
    <%= csrf_meta_tag %>
    <%= render 'layouts/stylesheets' %>
    <%= javascript_include_tag :defaults %>
</head>

_user.html.erb

<li>
<%= link_to user.name, user %>
<% if current_user.admin? %>
| <%= link_to "delete", user,   :method => :delete, :confirm => "You sure?",
                                :title => "Delete #{user.name}" %>
<% end %>
</li>

为什么这会将我重定向到用户个人页面而不是删除它们？
