DRY-ing up ActiveAdmin

I've got multiple resources in my ActiveAdmin installation that share quite a lot of the same traits, like:

What is the best way to avoid duplicating this functionality across the different resources?

I have set up decorators to avoid duplicating functionality in the index view, but I'm not sure if (and how?) this could be used in the other cases.

You can also extend your module. For example:

module AccountManageable
  def has_manageable_account 
    permit_params :name, :email, :role, :avatar

    filter :name, as: :string
    filter :email, as: :string

    # ... other DSL methods
  end
end

and then in your admin

ActiveAdmin.register Admin do
  extend AccountManageable

  has_manageable_account
end

You need to extend the DSL with monkey patch:

module ActiveAdmin
  # This is the class where all the register blocks are evaluated.
  class ResourceDSL < DSL
    def your_custom_method attr
      #common code
    end
  end
end

Now you can use your_custom_method in your registered resource file.
