Setting the attribute of an object to be and attribute of another object

Im very new to Ruby on rails. I am trying to set a Product object (:userid) to the user object id (user.id). So far I have got this 

class Product < ActiveRecord::Base
  before_create :set_userid
  def set_userid
    self.userid = User.new(params[:id])
  end
end

Is there any other way to set the value before the product object is created?

Consider using associations to easily define relations between models using helpers like

Product    
belongs_to :user

User
has_many :products

Your code won't works because model doesn't have access to params. So, you should assign User instance in action of your controller:

def your_action
  ...
  product = ...
  product.user = User.new(params[:id])
