RoR 3將用戶限制爲每天2帖子

Question

我正在尋找客戶，限制我的用戶每天發帖超過兩次，每週發帖量不超過5篇。我有一個用戶和帖子模型/控制器。

我一直在看這些問題，但他們不是我正在尋找的。

Rails 3.1 limit user created objects

How do I validate a time in Rails? Limiting a user to post once a day

錯誤@ 20:44 13/03/2012從KandadaBoggu

NoMethodError in PostsController#create 

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

Answer 1

代碼試試這個：

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
