NoMethodError in PostsController#create

undefined method `beginnning_of_day' for 2012-03-13 20:36:11 +0000:Time

Answer 1

试试这个:

class User
  has_many :posts do

    def today
      where(:created_at => (Time.zone.now.beginning_of_day..Time.zone.now))
    end

    def this_week
      where(:created_at => (Time.zone.now.beginning_of_week..Time.zone.now))
    end
  end    
end


class Post
  belongs_to :user

  validate :user_quota, :on => :create  

private 
  def user_quota
   if user.posts.today.count >= 2
     errors.add(:base, "Exceeds daily limit")
   elsif user.posts.this_week.count >= 5
     errors.add(:base, "Exceeds weekly limit")
   end
  end

end
