Rails - Sep 2009 - Proper syntax for text field (less garbled)

I''m almost there... if someone could please help me :)

OK, if I have this in my .html.erb:

<%= button_to "Add to Cart" , :action =>
''add_to_cart'', :id =>
item, :amount => 3 %>

I get proper behavior.  But I''m trying to figure out how to wire up a
text field for :amount

<%= text_field_tag ''$'', @amount %></p>
<%= button_to "Add to Cart" , :action =>
''add_to_cart'', :id =>
item, :amount => @amount %>

Doesn''t work.  Does anybody have an idea of what would?

add_to_cart is now working with

  def add_to_cart
    item = Item.find( params[ :id ] )
    @cart = find_cart
    @cart.add_item( item, params[ :amount ] )
  end

Can anyone help??

Many TIA,
Craig

You need a form. What button_to does is create a form containing just
a button, whereas you  need a form containing both the textfield and
the submit button
