Rails scope find with current user

Question

I\'m using Rails 3 with Devise for user auth. Let\'s say I have a User model, with Devise enabled, and a Product model, and that a User has_many Products.

In my Products

Answer 1

I like to do this as follows:

class Product

  scope :by_user, lambda { |user|
    where(:owner_id => user.id) unless user.admin?
  }

end

this allows you to write the following in your controller:

Product.by_user(current_user).find(params[:id])
