linking to table and returning value

Question

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

Is the above sample from your schedules.haml formatted correctly? HAML relies on indentation. The "- else" should be aligned with the "- if". — steakchaser, Jul 30 '12 at 14:29
yes its formatted correctly, all im getting is the No Result for everyone item which isnt correct — Boss Nass, Jul 30 '12 at 14:30

Take a look at this site:

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

used `= schedule.results.present?` and got true where i expected, but now how come when i query i.e. schedule.results.for it doesnt return a result ? – Boss Nass Jul 30 '12 at 15:49
`schedule.result` (not plural) should return a schedule object. However, I'm not familiar with the .for method – Sabar Jul 31 '12 at 00:21
for is an object within my schedule model – Boss Nass Jul 31 '12 at 07:57
doing that i get `undefined method `result' for #` – Boss Nass Jul 31 '12 at 08:00

You could always try `Result.find(schedule.result_id).for` although this isn't optimal – Sabar Jul 31 '12 at 17:53
