I'm making a simple questionnaire app using RoR. I've got a model for Questions, a model for Answers, and a third model, Qa, for matching each question to five possible answers through foreign keys. So, each qa has a question and five answers , a1-a5, through belongs_to and a :foreign_key, and then a selected_answer field for specifying which answer was selected by the user. The selected_answer is also an Answer through a foreign key.
Here's the question: What do I use for the value of the radio button? I've tried the following:
<%= f.radio_button :selected_answer, :a1 %><%= @qa.a1.answer_src %> <br /> <%= f.radio_button :selected_answer, :a2 %><%= @qa.a2.answer_src %> <br /> <%= f.radio_button :selected_answer, :a3 %><%= @qa.a3.answer_src %> <br /> <%= f.radio_button :selected_answer, :a4 %><%= @qa.a4.answer_src %> <br /> <%= f.radio_button :selected_answer, :a5 %><%= @qa.a5.answer_src %> </p>
but when I submit the form it errors out with "Answer expected, got String." Instead of ":a1", I've also tried "@qa.a1", with the same result. How do I use the value of the radio button to signify a record (object?) without doing something hackish?
