RoR select tag options

Question

My model is given below

class Question < ActiveRecord::Base
  ANSWERS= ['Option 1', 'Option 2', 'Option 3', 'Option 4']
end

In the view <%= select(:question, :answer, Question::ANSWERS, {:include_blank => true}) %> outputs

<select name="question[answer]" id="question_answer">
  <option value=""></option>
  <option value="Option 1">Option 1</option>
  <option value="Option 2">Option 2</option>
  <option value="Option 3">Option 3</option>
  <option value="Option 4">Option 4</option>
</select>

I tried <%= select(:question, :answer, Question::ANSWERS.collect {|d| [d, Question::ANSWERS.index(d)]}, {:include_blank => true}) %> This yields

<select name="question[answer]" id="question_answer">
  <option value=""></option>
  <option value="0">Option 1</option>
  <option value="1">Option 2</option>
  <option value="2">Option 3</option>
  <option value="3">Option 4</option>
</select>

But I need the following output

<select name="question[answer]" id="question_answer">
  <option value=""></option>
  <option value="1">Option 1</option>
  <option value="2">Option 2</option>
  <option value="3">Option 3</option>
  <option value="4">Option 4</option>
</select>

In your second example, use:

<%= select(:question, 
           :answer, 
           Question::ANSWERS.collect {|d| [d, Question::ANSWERS.index(d) + 1]},
           {:include_blank => true}) %>
