Rails - Mar 2005 - NoMethodError in Event_type#create

I am new Ruby on Rails, so excuse me if my question seems pretty obvious.

I am trying to validate uniqueness of a filed:

class EventType < ActiveRecord::Base

	belongs_to :sport
	validates_uniqueness_of :event_type
	
end

When I run it, I get this error message:
 Showing /event_type/new.rhtml where line #27 raised undefined method
`each'' for nil:NilClass

<select name="event_type[sport_id]">
27:    <% @sports.each do |sport| %>
28:        <option value="<%= sport.id %>" 
29:          <%= '' selected'' if sport.id ==
@event_type.sport.id %>>
30:          <%= sport.sport %>

However, if I take validates_uniqueness_of off, i.e.:

class EventType < ActiveRecord::Base

	belongs_to :sport
	
end

everything works just fine.

What am I doing wrong?

Thank you,
eduard

What do you have in your event_type controller (action new)? You do 
have @sports defined there, don''t you?

yes, it''s defined:

class EventTypeController < ApplicationController
	layout "standard-layout"
	scaffold :event_type
	
	def new
		@event_type = EventType.new
		@sports = Sport.find_all
	end
 
end


It''s strange, I only get an error if I try to validate event_type.  It
works fine with no validations.

Thanks,
eduard
