我将我的 Rails 应用程序 2.0.2 更新到 2.3.5。我在管理部分使用活动脚手架。

我的代码中没有任何更改，但更新出现了问题。我有一个控制器“admin/user_controller”来管理用户。

这是控制器的代码：

    class Admin::UserController < ApplicationController

  layout 'admin'

  active_scaffold :user do |config|
    config.columns.exclude :content, :historique_content, :user_has_objet, :user_has_arme, :user_has_entrainement, :user_has_mission, :mp, :pvp, :user_salt, :tchat, :notoriete_by_pvp, :invitation
    config.list.columns = [:user_login, :user_niveau, :user_mail, :user_bloc, :user_valide, :group_id] #:user_description, :race, :group, :user_lastvisited, :user_nextaction, :user_combats_gagner, :user_combats_perdu, :user_combats_nul, :user_password, :user_salt, :user_combats, :user_experience, :user_mana, :user_vie
    config.create.link.page = true
    config.update.link.page = true
    config.create.columns.add :password, :password_confirmation
    config.update.columns.add :password, :password_confirmation
    config.create.columns.exclude :user_password, :user_salt
    config.update.columns.exclude :user_password, :user_salt
    config.list.sorting = {:user_login => 'ASC'}
    config.subform.columns = []
  end
end

这段代码没有随着更新而改变，但是当我进入这个页面时，我得到了这个错误：

    uninitialized constant Users

我搜索了 2 天，但我没有找到问题，请你帮帮我。

我猜它与您的控制器有关，也可能与型号名称有关（user_controller 而不是 users_controller，而您使用active_scaffold :user）。

我认为 Rails 正在寻找一个名为 users 的模型，而您的模型名为 user。您是否为此添加了变形规则？
