Retain Form Values on reset


I had to do something similar in my app. What you can do is create an
object that mimics ActiveRecord in your controller. By that, I mean
the object should have methods with the same names as the attributes
which return the attribute's value. Then pass that to a form helper,
and you should be golden.

Controller action:
   @user =[:user]) # User is a class you'll have to write

View template:
<% form_for :user, @user, :url => {:action => 'create'} do |f| %>
  <%= f.text_field :username %>
  <%= f.submit %>
<% end %>

The trick is that `f.text_field :username` will create a text field
and set its value to what is returned by calling `@user.username`.
