I've been stuck with this for days. I think I should be able to access a variable in a controller of one model, that is stored in another model easily?
I have four models: User - (1-1) - Profile - (1-M) - Appointment - (1-1) - Option. Options contains pricePerPerson and discount for an appointment. Appointments contains, among others, numPeople. I want to access the figure in the Options model for the pricePerPerson (and discount, if appropriate) and use it in the view show for Appointments. (@ <%= appointment.price = Option.pricePerPerson * numPeople %>) So far I haven't been able to do this and have had to resort to hard-coding a price per person. I would rather not hard-code that, if possible. I thought I could do this either of the two ways: Please can someone tell me how I might go about solving this without deleting any tables. I want to keep the database as is if possible. 1: as there is a belongs_to relationship between options and appointments - (Options belongs to appointments) Appointments Controller: def new @appointment = Appointment.new @appointment.price = option.appointment.pricePerPerson end appointments/show.html.erb: <p> <strong>Price:</strong> <%#= 5 * @appointment.numpeople %> <%= @appointment.price * @appointment.numpeople %> </p><br> 2: Something like this: Appointments Controller: def new @appointment = Appointment.new pricePerPerson = params([:appointment]) price = Option.find(pricePerPerson) @appointment.price = price.pricePerPerson end -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
