linking to table and returning value

i am trying to query a table and return a value if the conditions are met.

schedule model

class Schedule < ActiveRecord::Base
  belongs_to :result
  attr_accessible :result_id
end

results model 

class Result < ActiveRecord::Base
  has_one :schedule
  attr_accessible :against, :for, :schedule_id
end

schedules.haml

- if schedule.result
  Result
- else
  No Result

all im getting is No Result, even though i know there is results loaded for the scheduling id

any help would be great thanks

  • Take a look at this site:

    http://rubyquicktips.com/post/3096503536/how-to-check-if-objects-or-relations-exist

    You may want to try something like 

    schedule.result.any?

    Also, try:

    raise schedule.result.to_yaml

    to see exactly what is returned by this statement
