Activeadmin Custom Views Which Retain the Activeadmin Layout

ActiveAdmin custom views which retain the ActiveAdmin layout

Problem solved. Just add layout 'active_admin' to your code :

controller do
  layout 'active_admin' # <-- here
  def index
    @search = Page.includes(:translations).where("page_translations.locale='fr'").metasearch(params[:search])
    @pages = @search.page params[:page]
  end

  def edit
    @page = Page.find params[:id]
  end
end

Customise layout (components ) for activeadmin

The activeadmin layout components are very easy to customize. What you need to do: Just define a module that opens ActiveAdmin::View.

you can have a custom_activeadmin_components.rb in initializers or admin directory where you defined all of your activeadmin resources. I prefer to put it in the directory where your activeadmin resources are. Then override any module you want:

here is a sample:

module ActiveAdmin
  module Views
    class Header < Component
      def build(namespace, menu)
        super(:id => "header")

        @namespace = namespace
        @menu = menu
        @utility_menu = @namespace.fetch_menu(:utility_navigation)

        build_site_title
        build_global_navigation
        build_utility_navigation
        #you can add any other component here in header section 
      end

      def build_site_title
        render "admin/parts/logo"
      end

      def build_global_navigation
        render "admin/parts/main_nav"
      end

      def build_utility_navigation
        render 'admin/parts/language_options'
        insert_tag view_factory.global_navigation, @utility_menu, :id => "utility_nav", :class => 'header-item tabs'
        render 'admin/parts/branch_in_header'
      end
    end

    module Pages
      class Base
        def build_page_content
          build_flash_messages

          div :id => :wizard_progress_bar do
            render 'admin/parts/wizard_progress_bar'
          end

          div :id => "active_admin_content", :class => (skip_sidebar? ? "without_sidebar" : "with_sidebar") do
            build_main_content_wrapper
            build_sidebar unless skip_sidebar?
          end
        end
      end
    end  
  end
end

Custom index views with ActiveAdmin

I ended up doing this using a technique described on their Google Group, in which you just shove the user over to a custom action:

https://groups.google.com/d/msg/activeadmin/YgMzeYBXRno/GZ01Epyq5lcJ

Hacky, yes. I think this is a much needed feature, so hopefully someone can fork and add in support for the index view to take a block with custom content.

Rails 4 - ActiveAdmin layout is blank but application layout works for custom controller action

Well, now i know what was the reason.Looking through the logs clearly mentioned something about the layout and when i searched the code, i founded out that there was a code to override the BaseController of ActiveAdmin.i removed that code now and now its working the way i want.i am sharing the code below that was causing the problem...

###admin/custom_layout.rb
###XXXXXXXXXXXXXXXXXXXXXXX    REMOVED THIS FILE ###########################
# module BaseControllerPatch
#   def determine_active_admin_layout
#     ##'activeadmin_custom_layout/application'
#     'active_admin'
#   end
# end

# module ActiveAdmin
#   class BaseController
#     prepend BaseControllerPatch
#   end
# end

Now i dont have any cusotm active_adin code and by default,its working perfectly without any need to add custom code.However, i want to add custom attributes in the body tag, which i can easily add in initializers/active_admin.rb

Hope this helps someone.

Custom active admin page with index action

make sure you have _index.html.erb file

views/admin/myname/_index.html.erb

Rails activeadmin redirect to customized view page from customse action

You may try this:

ActiveAdmin.register User do
  action_item :password_reset_action_item, only: :edit do
    link_to 'Reset', password_reset_admin_user_path(id: user.id)
  end

  member_action :password_reset do
    @user = User.find(params[id]) # tips: you can (& should) use `resource` to lookup records by id. it will save you a couple of lines when you integrate authorization adapters like cancancan/pundit
    render 'active_admin/users/password_reset' # you may omit this line if your template and action names are equal
  end
end

Active Admin custom 400, 500 error pages

into your routes:

match "/404", to: "errors#render_error"
match "/500", to: "errors#render_error"

build new controller called ErrorsController

class ErrorsController < ApplicationController

  def render_error
    exception   = env["action_dispatch.exception"]
    status_code = ActionDispatch::ExceptionWrapper.new(env, exception).status_code

    @method, @message = if status_code == 404
      ["not_found", env["REQUEST_URI"]]
    else
      ["server_error", "#{exception.message}\n#{exception.backtrace.join('\n')}"]
    end

    render status: status_code
  end
end

then in your ApplicationController:

private

  def not_found
    raise ActionController::RoutingError.new('Not Found')
  end

then create new view to show any html you want.

hope it helps you.
