I am new to Ruby and to Rails (using Ruby 1.9.3 and Rails 3.2.3) so I picked up the Agile Web Development book and have been working through it (apologies if this isn't the correct place for this question but the pragprog forums don't seem to work for me). I am currently working through the book and have reached the point where I am adding functionality to an "Add to Cart" button. Here is the code that was provided for the 'create' method in the line_item_controller:
def create @cart = current_cart product = Product.find(params[:product_id]) @line_item = @cart.line_items.build(product: product) ... end This results in the following error when I click "Add to Cart" Can't mass-assign protected attributes: product Can anyone shed some light on what is going on here (my search-fu has failed me)? The only way that I have been able to get this to work is by changing the code (starting at @line_item) to: @line_item = @cart.line_items.build @line_item.product = product Is this correct or is it just a band-aid fix that may cause issues going forward?
