Question

I have two models:

class country < ActiveRecord::Base
  has_many :companies
end

class company < ActiveRecord::Base
  belongs_to :country
end

In my view index for company I can show which country the company belongs to by showing the following:

<%= company.country_id %>

This will show me the id number it’s associated with, but I can’t seem to work out how to resolve this back to the country name which is country.name, everything I seem to try crashes rails, I don’t think I’m approaching the problem the correct way?

Answer 1

<%= company.country.try(:name) %>

really ought to do what you want.

Edited as comment suggested.
