Form data is not stored in DB - ruby

Question

My models:
class LineItem < ActiveRecord::Base
attr_accessible :itemable, :adults, :children
belongs_to :itemable, polymorphic: true
belongs_to :lead
belongs_to :cart
end
class Lead < ActiveRecord::Base
has_many :line_items, dependent: :destroy
def add_line_items_from_cart(cart)
cart.line_items.each do |item|
item.cart_id = nil
line_items << item
end
end
end
class House < ActiveRecord::Base
has_many :line_items, :as => :itemable
end
class Appartment < ActiveRecord::Base
has_many :line_items, :as => :itemable
end
item_controller
def create
#line_item = #cart.line_items.build itemable: #object
respond_to do |format|
if #line_item.save
format.html { redirect_to #line_item.cart,
notice: 'Vakantiehuis toegevoegd in lijst.' }
format.json { render action: 'show',
status: :created, location: #line_item }
else
format.html { render action: 'new' }
format.json { render json: #line_item.errors,
status: :unprocessable_entity }
end
end
end
private
def create_object
id = params[:house_id] || params[:appartment_id]
model = "House" if params[:house_id]
model = "Apartment" if params[:appartment_id]
model = model.constantize
#object = model.find(id)
end
lead_controller
def create
#lead = Lead.new(lead_params)
#lead.add_line_items_from_cart(#cart)
#lead.save
end
cart_controller
def create
#cart = Cart.new(cart_params)
end
private
def cart_params
params[:cart]
end
When the items are added from the house and aparment page..the visitor goes to the cart show template. The visitor can fill in number of adutls and children by a form (select).
- #cart.line_items.each do |item|
%tr.CartProduct
%td
.CartDescription
%p
= link_to item.itemable.name, polymorphic_url([item.itemable.country, item.itemable.region, item.itemable])
%td.CartProductThumb
%div
- item.itemable.attachments.take(1).each do |a|
= link_to(image_tag(a.file.url(:thumb)))
%td
.col-md-10
= form_for(item) do |f|
= f.select :adults, ['1', '2', '3', '4', '5'], :class => 'form-control'
%td
.col-md-10
= form_for(item) do |f|
= f.select :children, ['1', '2', '3', '4', '5'], :class => 'form-control'
= button_to "Checkout", new_lead_path, method: :get
The [cart_id] and the polymorphic [itemable_type][itemable_id]values are correctly stored in the line_items table, but not the form data :adults and children. What am i doing wrong ? Thanks remco
