Buildings have units. Units have rooms. Rooms have people. I can grab
building, room, and people IDs and store them in a session[:variable].
However, when creating a new unit, I need to give that
session[:building_id] to ActiveRecord for creation. I''m not sure
whether to use hidden fields or do it all in the model
''before_validation'' - in either case I don''t know
how. My attempt
failed with an ''Invalid method error'':
before_validation :set_building_id
def set_building_id
@unit.building_id = session[:building_id]
end
How can I add session variables to insert/create statements?

uhm sorry i don''t get the actual problem, but before_filter surely is the wrong place, plus in your above code @unit wasnt initialized in any way, so its no ARObject of the Uni Model and has no method/attribute "building_id" class Unitcontroller < ... def create @unit = Unit.new(params[:unit]) # if you have a hidden field with name="unit[building_id]", the building_id will be assigned with this command too. @unit.building_id = session[:building_id] # You can assign like this from the session., if you dont want to use a hidden field. @unit.save end end Hidden fields are more common for this type of thing imho.. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
