Find by id in the view template dynamically

Rails 3.1.3

I have a model 'Airline', whose STRING column is 'company' only. Also, another model 'Plan' has an INTEGER column 'airline_id'.

I would like to show the 'company' name (string) in a template like

      <% @plans.each do |plan| %>       Airline: <%= @airlines.find(plan.airline_id).first.company %><br />       ...       <% end %>

in the 'plans_controller.rb',

      @plans = Plan.all       @airlines = Airline.all

Obviously this does not work although no error appears. It shows 'Airline' all the same, where each plan should have a distinct airline company. Certainly the database stores the airline company names which correspond to the plans. The loop in the view template gives, however, the identical value.

Could anyone give some ideas that the template view shows distinct airline company corresponding to each plan?

Thanks.

i recon your model relation should be like this: plan belongs_to airline if so you could do this on the view: <% @plans.each do |plan| %> Airline: <%= plan.airline.company %> <% end %> meanwhile in the plans_controller.rb: @plans = Plan.all

hope this help

Thanks for your answer. It worked. I have totally forgotten the convenience association methods. Rails is great!
