Question

In a Rails 3 application that utilizes a MySQL database there are the following integers:

current_user.id is an integer
Questions table - id is an integer
Answers table - question_id and user_id are integers

In my controller:

@questions.each do |q|
  ans[q] = Answer.where("question_id = ? AND user_id = ?", q.id, current_user.id ) # this is line 27
end

Why do I get the following error:

can’t convert Question into Integer

app/controllers/applets_controller.rb:27:in []='
app/controllers/applets_controller.rb:27:inshow’
app/controllers/applets_controller.rb:25:in `show’

Thanks!

Maybe this will help you:

ans[q.id] = Answer.where("question_id = ? AND user_id = ?", q.id, current_user.id )
