If i have two models like Question and Answer. Question has three columns like question_id, question_type, question_text and Answer has three values answer_id, question_id, answer_text.
Question should generally not have a question_id field, it should just have the default id field. Unless that is you have some unusual requirements.
I am creating form for the Answer model.
Example:
<%= f.text_field :question_id %>. <%= f.hidden_field :question_id %>.
Here, I am using the hidden field to find the question_type. I tried the map method, but that doesn't work. So Somebody help me to get the question_type value by the selection of thatquestion_id.
You have not shown us the relationship between the models (has_many, belongs_to or whatever). That information is critical to answering the question.
