ruby-on-rails - RailsAdmin 仪表板定制

Question

我想在 RailsAdmin 仪表板上显示一些指标
我使用自定义 sql 查询从数据库中获取数据。

如何更改仪表板 View 以显示该数据？

我可以定制app/views/rails_admin/main/dashboard.html.erb app/views/rails_admin/main/dashboard.html.haml ，但是我在哪里定义查询结果

@result = Metric.data

谢谢

如果需要，您可以添加任意数量的仪表板

Rails 管理员配置

RailsAdmin.config do |config|
config.actions do
    dashboard
    require_relative '../../lib/rails_admin/config/actions/dashboard'

    root :admin_dashboard
    root :teacher_dashboard
    root :director_dashboard
end

访问默认仪表板时重定向到特定仪表板

/lib/rails_admin/config/actions/ dashborad.rb

require 'rails_admin/config/actions'
require 'rails_admin/config/actions/base'

module RailsAdmin
  module Config
    module Actions
      class Dashboard < RailsAdmin::Config::Actions::Base
        RailsAdmin::Config::Actions.register(self)
        register_instance_option :root? do
          true
        end
        register_instance_option :breadcrumb_parent do
        end
        register_instance_option :link_icon do
          'icon-hand-up'
        end
        register_instance_option :controller do
          proc do
            if current_user.instance_of? Teacher
              redirect_to '/admin/teacher_dashboard'
            elsif current_user.instance_of? Director
              redirect_to '/admin/campus_director_dashboard'
            elsif current_user.instance_of? Admin
              redirect_to '/admin/admin_dashboard'
            end
          end
        end
      end
    end
  end
end

管理仪表板 Controller 示例

/lib/rails_admin/config/actions/ admin_dashborad.rb

require 'rails_admin/config/actions'
require 'rails_admin/config/actions/base'
module RailsAdmin
  module Config
    module Actions
      class AdminDashboard < RailsAdmin::Config::Actions::Base
        RailsAdmin::Config::Actions.register(self)
        register_instance_option :root? do
          true
        end
        register_instance_option :breadcrumb_parent do
        end
        register_instance_option :link_icon do
          'icon-hand-up'
        end
        register_instance_option :controller do
          proc do
            render action: @action.template_name
          end
        end
      end
    end
  end
end
