Sorry for this basic noob question:
I have an “Item” class in my models which corresponds to a SQL table,
and a “Cart” class and a “CartItem” class which do not. The Item
class does not have an amount object, which is transitory, so I’ve put
this amount object in my CartItem class:
class CartItem
attr_reader :item, :amount
def initialize( item )
@item = item
end
def set_amount( amount )
This.amount = amount
end
end
I have a list of items in a viewer form, and I’d like to pass
associated amount to my CartItem when the user hits the “Add to Cart”
button. I’ve tried many variations of text_field and text_field_tag
in:
<% @items.each do |item| %>
…
<%= text_field( :amount , :action => ‘set_amount( :amount )’, :id =>
item )%>
<%= button_to “Add to Cart” , :action => ‘add_to_cart’, :id => item
%>
…
<% end %>
I know the text_field up there is severely mangled and won’t work–but
it’s an example of the 2000th try, the last several hundred out of
pure desperation. Can anyone help with the proper syntax for the
text_field in the .html.emb file?
The add_to_cart call with the button is working:
def add_to_cart
item = Item.find( params[ :id ] )
@cart = find_cart
@cart.add_item( item )
end
Many TIA,
Craig
