Rails ActiveAdmin: Incorrect breadcrumb

Question

I have model called Part which is using ActiveAdmin, CRUD operation works fine but the breadcrumb is not generating properly. Here is what I am getting in the breadcrumb on the EDIT page

 Admin / Parts / #<Part:0xcd74ef0> / 

I am using "activeadmin", "0.5.0"

Answer 1

In Active Admin for Custom breadcrumb

Try to define display_name in your Part model.

class Part < ActiveRecord::Base
  // Some Code
  def display_name
    "#{ id } #{ name }"
  end
end

Answer 2

You can use to_s method.

Define to_s method in Part model.

class Part < ActiveRecord::Base
  def to_s
    attribute_name.to_s
  end
end

     ]   
   end
