The user have to pay to use this app. At the beginning you can use the app for free for some days . You can get and use Egg coins in this app. Egg is the sole of the app. The Egg is the relationship between two friends. It's interesting.

Convert float values into indexes for user-specified buckets. Bucket is useful for creating group values, which can be passed to GROUP as input; Examples: my_group = bucket(rank(volume), range="0.1,1,0.1"); group_neutralize(sales/assets, my_group) my_group = bucket(rank(volume), buckets ="0.2,0.5,0.7", skipBoth=True, NANGroup=True); group_neutralize(sales/assets, my_group)

def current_user
@current_user ||= User.find(logged_in_user_id)；
def shipped?(order_id) @status ||= begin file = fetch_confirmation_file ; file? parse_confirmation_file(file) : {} end @status[order_id] == :shipped end
返回的是true or false； 而current_user 返回的是变异对象；如果不希望调用者修改缓存的变量，那应该考虑让被记忆化的方法返回冻结对象。

Enumerable模块的类，可对集合进行过滤，遍历和转化。map和select；还有个可以管理一切的方法 reduce(or inject), reduce可以转换结构；接受者，每个元素被调用一次，并产生返回值，累加器。 enum.reduce(0){|accumulator, element| accumulator + element} 0初始值；建议你总是使用一个带有起始值的累加器。 enum.reduce(0, :+);
数组转成Hash; array.reduce({}) {|hash, element| hash.update(element => true)}
users.select{|u| u.age>=21}.map(&:name) 获取大于等于21的names数组。比较低效；
User.reduce([]) {|names, user| names << user.name if user.age >=21 ; names}

And there's a default configuration file in config/deploy.yml that we can use, it's prefilled a little bit, it has the service name of the name of reaction, but we need to rename, for example, your user,the name of the image to go to my name of where I store this on Docker Hub. You can see we change that down in the registry as well and the name of the container image.
