How to have a different HTML id attribute for a check_box in a Rails form?

Question

Using the form helper for check boxes, I need to change the id attribute. Normally I have something like this:

<%= f.label :remember_me, 'Please remember me' %>
<%= f.check_box :remember_me %>

Problem is, I'm already using another HTML element on the page with id="remember_me" and this conflicts with that. So I tried changing this check_box to:

  <%= f.label :remember_me_top, 'me' %>
  <%= f.check_box :remember_me_top, 'remember_me' %>

That gives me an error... How do I have the name of the check box as remember_me, but the id of it as remember_me_top?

Answer 1

You can change checkbox id like this:

<%= f.label :remember_me, 'Please remember me', :for => "my_unquie_id" %>
<%= f.check_box :remember_me, :id => "my_unquie_id" %>

Also, if you want to change name attribute, add option to check_box: :name => "my_unique_name"
