Automatic numbering of form components

Hi,

Does anyone how to automatically put sequence number in view?

I have an inquiry form like below. However, the number of questions is more than 70, and they are deleted and/reordered in the future. So, I do not want to hard code the number. I was trying to create variable and increment on each question, but everything are displayed as 1.

I would appreciate if you could tell me any good way to manage this.

Thanks, Glenn

<%= start_form_tag :action => 'update' %> <% Integer @number = 0%> <div class="row"> <strong><%=h @number.next%>.</strong> ID Number: <%=text_field 'person', 'id_number' %> </div>

<div class="row"> <strong><%=h @number.next%>.</strong> Name: <%=text_field 'person', 'name' %> </div>

<div class="row"> <strong><%=h number.next%>.</strong> Email: <%=text_field 'person', 'email' %> </div>

...lots of fields...

Hey

Change .next to

@number += 1

and it will work

Cheers, Yuri

Change .next to

  > @number += 1

As a side note, if you use the    fixture_references plugin    http://agilewebdevelopment.com/plugins/fixture_references

, you can even use that trick in fixtures :

file: people.yml   <% @id=0 %>   john:     name: John     id: <%= @id+=1 %>   bill     name: Bill     id: <%= @id+=1 %>

Thank you so much Yuri and Alain! It worked fine, and it's good to know I can use this for fixtures.
