Rails - Sep 2012 - 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!
