please send me the code
Let me clear my reqt once again. I have three tables users, orders and line_items. Orders table have user_id and line_items have order_id. Now the following code is giving error: uninitialized constant UserController::Line_items
def search @orders = Order.find :all
this is horribly inefficient
session[:query] = params[:query].strip if params[:query] if session[:query] and request.xhr? @users = User.find(:all, :conditions => ["first_name LIKE ?", "%#{session[:query]}%"], :order => "first_name ASC") @product=Array.new @users.each do |user| @orders.each do |order| if user.id == order.user_id @id = order.id @var = Line_items.find_by_order_id(@id)
find_by_x is like a find :first. You probably want find_all_by_x The class name is LineItem (if you're adhering to the usual conventions). If you've defined your relationships properly, you could do something along the lines of
@product = @users.collect {|u| u.orders.collect(&:line_items)}.flatten
(eager loading those associations might be a good idea)
You seem to be stumbling over some really basic rails stuff. Find a good book on rails and read and understand it. AWDWR is a popular favourite, and there's a book you can get for free at http://www.sitepoint.com/books/rails1/freebook.php
