ruby-on-rails – 用户中的NoMethodError #index’未定义方法`每

<% @users.each do |user| %>

我不确定问题出在哪里.任何帮助是极大的赞赏.提前致谢.我知道我在这里错过了一些非常容易的东西.

用户/索引

<div class="page-header">
<center><strong><h1> All Users </h1></strong></center>
</div>

    <div class="row">
        <% @users.each do |user| %>
        <div class="horizontal-align col-md-2">
            <div class="user">
                <center><%= link_to image_tag(user.avatar.url(:thumb)),user %></center>
                <center><br><%= link_to user.name,user %></br></center>
                <% if current_user.admin %>
                <center><%= link_to "Delete",user,method: :delete,data: { confirm: "Are you sure?" } %></center>
                <% end %>
            </div>
        </div>
        <% end %>
    </div>
</div>

<div class="center">
<%= will_paginate @users,renderer: BootstrapPagination::Rails %>
</div>
</div>

用户/显示

<% provide(:title,@user.name) %>

 <div class="row">
    <aside class="span4">
        <section>
            <h1>
                <%= image_tag @user.avatar.url(:thumb) %>
                <%= @user.name %>
            </h1>


    <section>
      <%= render 'users/stats' %>
    </section>


    <% if current_user.following?(@user) %>
    <%= render 'users/unfollow' %>
    <% else %>
    <%= render 'users/follow' %>
    <% end %>

用户/控制器

class UsersController < ApplicationController

  before_action :correct_user,only: [:edit,:update,:destroy]
  before_action :authenticate_user!,except: [:index,:show]
  before_action :admin_user,only: :destroy


   def following
    @title = "Following"
    @user = User.find(params[:id])
    @users = @user.followed_users.paginate(page: params[:page])
    render 'show_follow'
   end

  def followers
    @title = "Followers"
    @user = User.find(params[:id])
    @users = @user.followers.paginate(page: params[:page])
    render 'show_follow'
  end


  def index
    @users = User.paginate(page: params[:page],:per_page => 20)
  end


  def show
    @user = User.find(params[:id])

    if @user 

      @posts = @user.posts.order("updated_at DESC")
      render actions: :show
    else
      render file: 'public/404',status: 404,formats: [:html]
  end  
  end

  def destroy
    User.find(params[:id]).destroy
    flash[:success] = "Your account has been deleted."
    redirect_to root_path
  end

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

  def admin_user
      redirect_to root_path unless current_user.admin?
  end
