activeadmin with rails API app errors:Admin :: DashboardController #index中的ArgumentError

Question

我正在尝试将活动管理员与rails_api应用程序合并.

细节:

因为它是一个API,没有cookie和东西,我使用devise_auth_token进行身份验证(不是设计).

身份验证工作正常.但是,我现在正尝试将活动管理员与此相结合,并按照以下步骤操作:

gem 'activeadmin', '1.0.0.pre2'
$ bundle install
$ rails g active_admin:install 
$ rake db:migrate db:seed
$rails server

在转到http:// localhost:3000/admin时,它出现以下错误:

ArgumentError in Admin::DashboardController#index
wrong number of arguments (given 1, expected 0)

指向一行:define_method(name) doin:

 if instance_reader
    remove_possible_method name
    define_method(name) do
      if instance_variable_defined?(ivar)
        instance_variable_get ivar
      else

但请注意,直接转到http:// localhost:3000/admin/login会打开登录页面,但在登录后,它会重定向回http:// localhost:3000/admin并显示相同的错误消息.

的Gemfile:

gem 'pg'
gem 'devise'
gem 'devise_token_auth'
gem 'omniauth'
gem 'money-rails'
gem 'swagger-docs'
gem 'activeadmin', '1.0.0.pre2'gem 'pg'
gem 'devise'
gem 'devise_token_auth'
gem 'omniauth'
gem 'money-rails'
gem 'swagger-docs'
gem 'activeadmin', '1.0.0.pre2'

routes.rb中:

Rails.application.routes.draw do
  devise_for :admin_users, ActiveAdmin::Devise.config
  ActiveAdmin.routes(self)
  namespace :api do
    namespace :v1 do
      mount_devise_token_auth_for 'User', at: 'auth'
      ...
    end
  end
  root to: "home#index"
end

依赖关系:

• Ruby:2.3.0
• Rails:4.2.4
• 活动管理员:1.0.0.pre2
• Rails API:0.4.0
• 设计:3.5.6
• 设计令牌身份验证:0.1.37

我怀疑它可能与rails_api默认情况下不包括几个rails中间件的事实有关......但实际上,我不知道它是什么,或者我怎么能去做.请任何人,我需要帮助.

我的组合甚至可以工作吗？

使用devise_auth_tokenwith 时这是一个问题active_admin

这是devise_token_auth宝石本身的工作原理.

出于某种奇怪的原因,ActiveAdmin从您自己的应用程序的ApplicationController扩展而来.如果您在应用程序的ApplicationController中包含DeviseTokenAuth :: Concerns :: SetUserByToken问题,这将成为一个问题.

解决方案是使用两个单独的ApplicationController类 - 一个用于API,另一个用于ActiveAdmin.像这样的东西:

应用程序/控制器/ api_controller.rb

API路由从此控制器扩展

class ApiController < ActionController::Base
  include DeviseTokenAuth::Concerns::SetUserByToken
end

应用程序/控制器/ application_controller.rb

将此保留给ActiveAdmin和任何其他非api路由

class ApplicationController < ActionController::Base
end

这是参考
