Rails 3 and ActiveAdmin. Filter displays objects not company name

Question

I have a list of clients, but in the filter section in the right column I get a list similar to this #<Customer0X0B500> in the selection menu. How can I display the company_name attribute of a client instead?

Answer 1

It turned out, thanks!

filter :customer, :collection => proc {(Customer.all).map{|c| [c.company_name, c.id]}}

Answer 2

I'm not sure I understand you, but you should probably define the to_s method inside your Customer class, for example.

 class Customer def to_s self.company_name end end 

it would be easier if you shared some code

Answer 3

 class Customer def display_name self.company_name end end 

Defining the name display_name instead of to_s works better ...

• to_s can be called automatically by other objects.
• display_name only affects ActiveAdmin

You can also define:

 show :title => :display_name 

This will cause your company name to appear as the name on the watch pages, not Company #x.

Answer 4

So that the ActiveAdmin display selection menu is used correctly in Model.rb: -

alias_attribute: name ,: category_name
