Hi I am trying to make a small survey app and started to get a little confused. So far i have survey.rb has_many :answers answer.rb belongs_to :survey So Survey will have many answers, and answer will belong to only one survey. This part works fine. Now i want to record survey results (you can only pick ONE answer, it will NOT be a multiple answer survey). To do this, as far as i know i should create anwsers_surveys table and setup proper habtm relations or create a new model and go with :through. Is this the way to go?, since i am not really trying to make a real habtm between surveys and answers but need to record the results.

why not just have a score column in the answers table?

Pawel, Step back from ActiveRecord for a bit and examine your problem domain. If a survey can have multiple answers and and answer can have multiple surveys then you have already answered your own question! i.e. you will need a link table either with the habtm (deprecated) or the first class model approach (:through) I write this response with the assumption that "answer" is equivalent to "result". If I am mistaken then please forgive the confusion. HTH ilan

Thanks for responses! Chris H. wrote: > why not just have a score column in the answers table? Yup. So simple solution and it fits just right for my problem. I gotta start drawing my models and relations on paper before i start making decisions i guess. Ilan, You are right if a survey could have multiple anwsers and answer can have multiple surveys but that's not the case. Chris solution fits.
