Question

I installed Ruby on Rails Gem Active Admin and made association between tables.

Category 
with fields (category_name:string)

with

SubCategory
with fields (sub_category_name:string, category_id:integer)

but when i view admin console for subcategory in drop down for categories instead of their name encrypted string is coming which refers to category id. Its like:

#<Category:0x698a648>
#<Category:0x6958998>

I want category name to be here. I know def to_s function can do it but in active admin gem i am not sure where to write this function.

Any Idea will be highly appreciated..

Answer 1

You could code the to_s method in the class and return the category name:

#app/models/category.rb
class Category    
  #...

  def to_s
    category_name
  end
end
