Rails 3 and ActiveAdmin. Filter is displaying Objects not the company name

Question

I have a list of customers but on the filter section on the right column, I get a list like this #<Customer0X0B500> in the select menu. How can I display the company_name attribute of Customer instead?

Answer 1

Figured it 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 probably you should define to_s method inside your Customer class e.g.

class Customer

  def to_s
    self.company_name
  end

end

it would be easier if you shared some code
