<% (1..@question.qvalues_count.to_i).each do |qvalue| %>
    <% case qvalue
         when 1
          answer_value = @answer.value1
        when 2
          answer_value = @answer.value2
        when 3
          answer_value = @answer.value3
        when 4
          answer_value = @answer.value4
        when 5
          answer_value = @answer.value5
        end %>
       <label for="answer[value<%=qvalue%>]" class="fieldLabel" >Value<%=qvalue%></label>
      <input type="text" id="answer[value<%=qvalue%>]" name="answer[value<%=qvalue%>]"
        value="<%=answer_value%>"
      />
   <% end %>

values = {1 => 'my value 1', 2 => 'my value'}
answer_value = values[qvalue]

class Answer
  def value(i)
    self.send("value#{i}")
  end
end

<% answer_value = eval( '@answer.value' + qvalue.to_s ) %>

<% answer_value = @answer.send( 'value'+qvalue.to_s) %>

<% answer_value = @answer.send( 'value#{qvalue}' ) %>
