How to insert rows in a many-to-many relationship
- by GSound
Hello,
I am having an issue trying to save into an intermediate table. I am new on Rails and I have spent a couple of hours on this but can't make it work, maybe I am doing wrong the whole thing. Any help will be appreciated. =)
The app is a simple book store, where a logged-in user picks books and then create an order.
This error is displayed:
NameError in OrderController#create
uninitialized constant Order::Orderlist
These are my models:
class Book < ActiveRecord::Base
has_many :orderlists
has_many :orders, :through => :orderlists
end
class Order < ActiveRecord::Base
belongs_to :user
has_many :orderlists
has_many :books, :through => :orderlists
end
class OrderList < ActiveRecord::Base
belongs_to :book
belongs_to :order
end
This is my Order controller:
class OrderController < ApplicationController
def add
if session[:user]
book = Book.find(:first, :conditions => ["id = #{params[:id]}"])
if book
session[:list].push(book)
end
redirect_to :controller => "book"
else
redirect_to :controller => "user"
end
end
def create
if session[:user]
@order = Order.new
if @order.save
session[:list].each do |b|
@order.orderlists.create(:book => b) # <-- here is my prob I cant make it work
end
end
end
redirect_to :controller => "book"
end
end
Thnx in advance!
