I have this form_for: <%= form_for [post, Comment.new,], :remote => true do |f| %>

I have this form_for:

<%= form_for [post, Comment.new,], :remote => true do |f| %>
<%= f.text_area :content, :cols =>10, :rows => 1%>
<% end %>
<%= f.submit :class => "input_comment"  %>

That generate the next code html:

<form method="post" id="new_comment" data-remote="true" class="new_comment" 
action="/post/4efcda9e1d41c82486000077/comments" accept-charset="UTF-8"><div 
style="margin:0;padding:0;display:inline"><input type="hidden" value="✓" name="utf8">
<input type="hidden" value="ctVfDF/O4FIR91I7bC5MVezQmutOCkX3dcXe73uNPZY=" name="authenticity_token">

<textarea rows="1" name="comment[content]" id="comment_content" cols="10"></textarea>
<input type="submit" value="Create Comment" name="commit" class="input_comment">
</form>

If I have many forms in a same page is not a html valid with the same id.

  • The id for form_for generate id=”new_comment”
  • The id for textarea generate id=”comment_content”

With so many forms in a same page is not valid html.

How can I change the id autogenerate by form_for method helper from rails 3.1?

    Adding on to what miked said, the easiest way to make unique form id’s for the posts would be to use the post’s id numbers in the id attribute, like so:

    <%= form_for [post, Comment.new,], :remote => true, :html => { :id => "new_comment_on_#{post.id}" } do |f| %>
