将rails_admin与rails_api一起使用

Question

我最初在rails_api GitHub上发布了这个问题,但现在由于不活动而在此发布.

我正在尝试使用rails_adminRails 5 API应用程序.我添加了额外的ActionController模块,以至于我可以使用有效的rails_admin面板或工作API请求.问题似乎是rails_admin依赖于ActionView::Layouts,包含后会导致API请求出现问题.

的Gemfile:

gem 'rails', '>= 5.0.0.beta3', '< 5.1'
...
gem 'rack-pjax', github: 'afcapel/rack-pjax'
gem 'remotipart', github: 'mshibuya/remotipart'
gem 'kaminari', github: 'amatsuda/kaminari', branch: '0-17-stable'
gem 'rails_admin', github: 'sferik/rails_admin'

我配置我的应用程序使用ActionDispatch::Flash:

module MyApp
  class Application < Rails::Application
    ...
    config.middleware.use ActionDispatch::Flash
  end
end

我为Rails API,ApplicationController 配置了额外的模块:

class ApplicationController < ActionController::API
  include Knock::Authenticatable
  include Pundit

  # RailsAdmin support
  include AbstractController::Helpers
  include ActionController::Flash
  include ActionController::RequestForgeryProtection
  include ActionController::MimeResponds
  include ActionController::HttpAuthentication::Basic::ControllerMethods
  include ActionView::Layouts
end

通过这些更改,Rails管理仪表板似乎运行正常.但是,当我尝试访问应用程序中的JSON资源时,会引发以下错误:

Error:
BookingsControllerTest#test_should_get_index:
ActionView::MissingTemplate: Missing template bookings/index, application/index with {:locale=>[:en], :formats=>[:json], :variants=>[], :handlers=>[:raw, :erb, :html, :builder, :ruby, :haml]}. Searched in:
  * "/Users/richard/.rbenv/versions/2.3.0/lib/ruby/gems/2.3.0/bundler/gems/rails_admin-355dc80f8a20/app/views"

测试代码(也尝试添加format: :json):

class BookingsControllerTest < ActionController::TestCase
  test 'should get index' do
    get :index

    assert_response :success
  end
end

这是控制器代码:

class BookingsController < ApplicationController
  def index
    @bookings = find_bookings
    render json: @bookings, include: ['customer', 'client'], meta: meta
  end
end

这只发生在我将ActionView::Layouts模块包含在顶级ActionController::API类中以支持Rails Admin之后.

如果我是你,我会尝试隔离API和RailsAdmin控制器.我认为这必须奏效:

class ApplicationController < ActionController::API
  include Knock::Authenticatable
  include Pundit
end

class RailsAdminCustomController < ApplicationController
  # RailsAdmin support
  include AbstractController::Helpers
  include ActionController::Flash
  include ActionController::RequestForgeryProtection
  include ActionController::MimeResponds
  include ActionController::HttpAuthentication::Basic::ControllerMethods
  include ActionView::Layouts
end

在 config/initializers/rails_admin.rb

RailsAdmin.config do |config|
  # other config stuff ...
  config.parent_controller = '::RailsAdminCustomController'
end

只是检查RailsAdmin::ApplicationController 这里,和配置设置在这里.
