Model.create?


#1

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 #{@item.inventory.name}
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,
