我在pg数据库的现有应用程序上安装了activeadmin
当我去： http://localhost:3000/admin
我收到了一个错误：
uninitialized constant AdminController
我在安装activeadmin之后确实db:migrate
试图重新安装activeadmin，但它没有解决这个问题
我的溃败.rb：
Rails.application.routes.draw do
devise_for :admin_users, ActiveAdmin::Devise.config
resources :admin
resources :posts
resources :categories
resources :statuses
root :to => "home#index"
ActiveAdmin.routes(self)
# For details on the DSL available within this file, see http://guides.rubyonrails.org/routing.html

的Gemfile：

git_source(:github) do |repo_name|
repo_name = "#{repo_name}/#{repo_name}" unless repo_name.include?("/")
"https://github.com/#{repo_name}.git"
