Newbie question

URL:

/categories/new?parent_id=6

Controller:

def new
    @category = Category.new( :parent_id => params[ :parent_id ] )
end

View:

<%= form_for( @category ) do |f| %>
<%= f.hidden_field :parent_id %>
<% end %>

Source of the page:

<input id="category_parent_id" name="category[parent_id]" type="hidden" />

Why isn’t the value being passed through?

EDIT: I realized after that I didn’t have :parent_id as part of my attr_accessible in my model Category. Everything’s working as it should now. Thanks for the help guys.

EDITED after @Ceilingfish wise remark

Try this:

<%= form_for( @category ) do |f| %>
  <%= f.hidden_field :parent_id, :value => params[:parent_id] %>
<% end %>
