Hi,
I have a view that displays a list of items from a database table called
"order_items". Each item has a checkbox next to it. I need the user to
be able to select multiple items with the checkboxes and have those
items update another database table called "line_items". Whenever I
save
the form, in the "line_item_id" column of the
"order_item_id" table I
keep seeing stuff like "-615326988", which is obviously incorrect.
What
is that weird negative number? Why does it put that instead of what I
need?
Below is what I''m working with so far...
Controller:
[CODE]
def create
@order = Order.new(params[:order])
@lineitem = LineItem.new(params[:line_item])
@orderitem = OrderItem.find(:all)
if @order.save
@lineitem.order_id = @order.id
@lineitem.order_item_id = @orderitem.id
if @lineitem.save
LineItem.update_all(["issued_date=?", Time.now], :id =>
params[:orderitem_ids])
redirect_to :controller=> ''orders'', :action =>
''viewAllOrders''
else
flash[:warning] = "Error - orders controller - @lineitem not
saved."
end
else
flash[:warning] = "Error - orders controller - @order not saved."
end
end[/CODE]
View:
[CODE]
<% form_tag({:action => ''create''}, {:id=>
''page1''}) do %>
<% @orderitem.each do |orderitem| %>
<%= check_box_tag "orderitem_ids[]", orderitem.id %>
<%= orderitem.name %>
<% end %>
<% end %>[/CODE]
Output:

I don''t understand your code very well, but i think that you need something like this: http://wiki.rubyonrails.org/rails/pages/CheckboxHABTM The answer about the negative id is on:>> @orderitem = OrderItem.find(:all)...>> @lineitem.order_item_id = @orderitem.id@orderitem is an Array!

Thank you for your reply Everton. I will look into HABTM and HABTM checkboxes. I''m still confused about the negative id. Everything I try either produces the same result or makes the order_item_id NULL. Can you give a hint on what I should be adding/subtracting from the code? What should @orderitem be instead of an array?> The answer about the negative id is on: >>> @orderitem = OrderItem.find(:all) > ... >>> @lineitem.order_item_id = @orderitem.id > > @orderitem is an Array!-- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

I think that what you need is just a checkbox like: <%= check_box_tag "line_item[orderitem_ids][]", orderitem.id %> And so, @lineitem = LineItem.new(params[:line_item]) @lineitem.save will works fine! P.S.: the problem about the negative Array id, is because the Array id is the Ruby object id, not an ActiveRecord id.

OK, when I try <%= check_box_tag "line_item[orderitem_ids][]", orderitem.id %> it shows the error: "NoMethodError in OrdersController#create undefined method `orderitem_ids='' for #<LineItem:0xb69024e4>" When I try <%= check_box_tag "line_item[orderitem_ids][]" it shows: "ActiveRecord::StatementInvalid in OrdersController#create Mysql::Error: Table ''databasename.line_items_order_items'' doesn''t exist: SHOW FIELDS FROM line_items_order_items" Yes, Thufir, HABTM looks very promising. I haven''t had much time to look into it yet though. Everton J.

Your OrderItem model has not the belongs_to :line_items, but this is not the problem. I can''t understand why method missing, because you have has_many :order_items... Well, sory, but i can''t help more. On Dec 27, 2007 12:15 AM, Mr. Bill <rails-mailing-list-ARtvInVfO7ksV2N9l4h3zg@public.gmane.org> wrote:> > Everton J.

It seems contentious, but to my understanding it would be: class Order class Item class ItemOrder corresponding to: table orders table items table items_orders or, perhaps it''s item_orders, or order_items for the table name. That part seems contentious. Oh, I find "item" to be kinda vague as it could be any kind of item. How about "dish", "entree" or "food"? -Thufir --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

items_orders is correct, as HABTM join tables need to be in alphabetical order. Well, apparently.
