我目前正在使用Mongoid ORM的rails項目。我在服務器端使用Rails管理寶石進行數據處理。 Rails版本是4.1.7，Ruby是2.1.5。問題是第一次加載管理面板時需要花費很多時間。Rails管理面板加載緩慢
我檢查了導軌的日誌。它似乎從「用戶」表中查詢每個用戶，當然加載面板的時間與用戶表中的條目數成正比。
請幫我加速面板的加載。如果需要其他信息，請詢問。謝謝。
以下是rails日誌的快照。

Ability.rb
class Ability
include CanCan::Ability
def initialize(user)
# Define abilities for the passed in user here. For example:
#
# user ||= User.new # guest user (not logged in)
# if user.admin?
# can :manage, :all
# else
# can :read, :all
# end
#
# The first argument to `can` is the action you are giving the user
# permission to do.
# If you pass :manage it will apply to every action. Other common actions
# here are :read, :create, :update and :destroy.
#
# The second argument is the resource the user can perform the action on.
# If you pass :all it will apply to every resource. Otherwise pass a Ruby
# class of the resource.
#
# The third argument is an optional hash of conditions to further filter the
# objects.
# For example, here the user can only update published articles.
#
# can :update, Article, :published => true
#
# See the wiki for details:
# https://github.com/CanCanCommunity/cancancan/wiki/Defining-Abilities
if user && user.admin_type == 1
can :access, :rails_admin # only allow admin users to access Rails Admin
can :dashboard
can :manage, :all
end
if user && user.is_admin?
can :access, :rails_admin # only allow admin users to access Rails Admin
can :dashboard
can :read, :all
can :manage, :statistic

編輯：我解決了這個問題（見答案）。但我仍然想知道它爲什麼加載速度很慢的原因。幫助表示讚賞。
