Rails, CamalCase Model Name retrieving related record in view?

I have two mod开发者_如何学Goels Location and LocationType.

class LocationType < ActiveRecord::Base 
  has_many :locations
end

class Location < ActiveRecord::Base
  belongs_to :location_type
end

In my Location model I have the foreign key: location_type_id

In my view I try and call:

 @location.location_type.name

but I get an error:

undefined method `name' for nil:NilClass

How do I get the view to display the location_type related record?

Check the location_type_id on your Location object. If there is no LocationType object with that id, then @location.location_type will return nil.
