Rails 3和ActiveAdmin。 过滤器显示的是对象而不是公司名称

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

想出来，谢谢！

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 eg

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 display_name instead of to_s works better...

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

You can also define:

show :title => :display_name

This will make your company_name appear as the title on the view pages instead of Company #x.

Answer 4

To make ActiveAdmin display select menu properly try in Model.rb:-

alias_attribute :name, :category_name
