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

You could add a class method on Product with the user sent as an argument.

class Product < ActiveRecord::Base
  ...

  def self.for_user(user)
    user.admin? ? where({}) : where(:owner_id => user.id)
  end

Then you can call it like this:

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

PS: There's probably a better way to do the where({}).
