I am getting a error in accessing q.questions .. question is column in table.

pls help.

Answer 1

You need to do - q.first.question . Your q is a collection of questions not an instance of Question . And you called question method on the collection of questions, that's why you got the error.

Answer 2

In your case q is question collection

q.each do |que|
  puts que.question
end
