Model.create ?

I have two models (Transaction and RentedItem).

Transaction.rb   has_many :rented_items   has_many :inventories, :through => :rented_items

  def add(inventory_id)     items = rented_items.find_all_by_inventory_id(inventory_id)     inventory = Inventory.find(inventory_id)     if items.size < 1       ri = rented_items.create(:inventory_id => inventory.id,                                :amount => 1,                                :price => inventory.price)     else       ri = items.first       ri.update_attribute(:amount, ri.amount + 1)     end     ri   end

Controller

def add     @inventory = Inventory.find(params[:id])     @item = @transaction.add(@inventory.id) <= where @transaction is set in a before_filter     flash[:notice] = "Added <em>#{@item.inventory.name}</em>"     redirect_to :controller => "inventory", :action => "list"   end

Problem I dont receive any errors and when list in rendered I see the correct flash[:notice]. In the add method inside Transaction.rb the object is created and return but when I look in the database no record was saved. I am completely lost on why the record wont save but is being created.

***I even tried RentedItem.create(...) in the controller to remove all confusion from the controller to model ... and it still wont work.***

Could someone point me in any direction? Thanks

Having an association called transaction is a bad idea as the accessor
methods generated will overwrite the transaction method (which is used
when saving)

I was just in the middle of renaming everything and creating new models to see if it would help. Good to know I am already on the right track.

Thanks a lot,
