best way to add actions about activeadmin HOT 14 CLOSED

The best way is to use the "member_action" and "collection_action" methods. I am in the process of writing the docs for them right now. Until then, this should do:

ActiveAdmin.register Post do

  # Available at /admin/posts/1/approve and #approve_admin_post_path(post)
  member_action :approve, :method => :post do
    # Just a regular controller method in here
    post = Post.find params[:id]
    post.approve!
    redirect_to admin_post_path(post)
  end

  # The exact same api is available for collection actions
  # Available at /admin/posts/some_collection and #some_collection_admin_posts
  collection_action :some_collection

end

Checkout the methods in the DSL at https://github.com/gregbell/active_admin/blob/master/lib/active_admin/dsl.rb#L118

To get the layout in your view it's also nice having this:
render "name_of_your_template", :layout => "active_admin"
It's not valid with a partial, only with a template, as far as I know.

Woooooooo... worked perfectly. No need for routes. Awesome again.

from activeadmin.

Oh, nice! This is just what I was looking for :)

I've added a member action similar to the above example, however it doesn't include a redirect.
The action renders fine, except for it has no layout; has anyone had this problem? If so, how did you overcome it?

from activeadmin.

Hi, I also don't get the layout. Have you solved this issue?

from activeadmin.

Not solved, but hacked into existence with the following:

# app/config/initializers/active_admin.rb

require 'inherited_views'

module ActiveAdmin

  class ResourceController < ::InheritedViews::Base

    protected

    def renderer_for(action)
      if %w(index new create edit update destroy show).include?(action.to_s)
        ActiveAdmin.view_factory["#{action}_page"]
      else
        ActiveAdmin.view_factory["abstract_page"]
      end
    end

  end

  module Views
    module Pages
      class AbstractAction < Base

        def title
          params[:action].to_s.titleize
        end

        def main_content
          render(params[:action])
        end

      end
    end
  end

  class ViewFactory < AbstractViewFactory
    register :abstract_page => ActiveAdmin::Views::Pages::AbstractAction
  end

end

If, for example, you had a member action called preview on a Post resource, you would create a corresponding action template with the html.arb extension:

# app/views/admin/posts/preview.html.arb
render renderer_for(:preview)

This will render the AbstractPage view factory which will, in turn, render a preview partial.
You can then create this partial (erb, arb, haml, whatever) and fill it with the approriate content.

This is by no means a sustainable way to do things, but it seems to work.

It would be nice if member_action also added an action to the default_actions in the index :P

i agree with zequez

from activeadmin.

I have something like this

   member_action :blow, :method => :post do
      puts "$"*30
      puts "Doing something!"
      puts "$"*30
      redirect_to admin_cluster_path, notice: "Did you notice that?!"
    end

However the route is not added of the resource and I get the following error:

Routing Error
No route matches [GET] "/backend/admin/clusters/12345/blow"

from activeadmin.

@IslamAzab There is no route for the get verb on that action. There is a route for post on that action. If you're using a link, I might suggest using :method => :put and making sure you add the :method => :put option on your link_to.

@shekibobo Oh, my bad. What you've suggested will work just fine. Thanks!

from activeadmin.

thank you @gregbell
