Michael Hartl Ruby on Railsチュートリアル(Rails 3用)

を完了しました。localhost:3000 / users / adminsのページですべての管理者ユーザーのリストを取得しようとしていますが、移動するとエラーが発生します。ページ管理者に。localhost:3000 /usersページの下にすべてのユーザーのリストもあります
。発生するエラーは次のとおりです。

ActiveRecord :: RecordNotFound in UsersController#show
id =
admins app / controllers / users_controller.rb:7:in'show'のユーザーが見つかりませんでした
パラメーター:
{"id" => "admins"}

Railsコンソールで、次の行を使用してuseradmin属性を呼び出すことができます。admins = User.where(:admin => "t")

users_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 show
    @user = User.find(params[:id])
    @microposts = @user.microposts.paginate(:page => params[:page])
    @title = @user.name
    @admins = User.where(:admin => "t")
  end

  def new
    @user = User.new
    @title = "Sign up"
  end

  def create
    @user = User.new(params[:user])
    if @user.save
      sign_in @user
      flash[:success] = "Welcome to University Sports!"
      redirect_to @user
    else
      @title = "Sign up"
      render 'new'
    end
  end

  def edit
    @title = "Edit user"
  end

  def update
    @user = User.find(params[:id])
    if @user.update_attributes(params[:user])
      flash[:success] = "Profile updated."
      redirect_to @user
    else
      @title = "Edit user"
      render 'edit'
    end
  end

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

  #def admins
  #  @users = User.admins
  #  render "users/index"
  #end

  def admins
    @admins=User.where(:admin => "t")
  end

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

  def following
    @title = "Following"
    @user = User.find(params[:id])
    @users = @user.following.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  

  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

/ users/adminsのルーティングファイルに手動パスを作成する必要がある場合があります。問題は、Railsが(GET)/ users / * *のルートを既に構成してUsersController#showに直接ルーティングすることです。これは、通常、ユーザーID(たとえば、/ users / 222)で表示を実行する場合があるためです。

試す

match '/users/admins',  :to => 'users#admins'
