红宝石 - 插入数组基于百分比 [英] Ruby - insert into an array based on a percentage

问题描述

我有一个名为 TestSubject ，我可以用它来访问以下数据的对象，名称和百分比我想根据百分比来插入名字，到一个数组。因此，例如，

arr.push（TestSubject.name）基于TestSubject的百分比，在这种情况下，它的提出TestSubject.percent＃=＆GT; 90

这意味着这个特定的名称有被推到阵列的90％的机会。我并不怎么过知道如何写在Ruby中的语法。

任何想法？

解决方案

  arr.push（TestSubject.name）如​​果兰特（100）LT = TestSubject.percent
 

I have an object called TestSubject which I can use to access the following data, name and percent I want to insert the name based on the percent, into an array. so for example,

arr.push(TestSubject.name) based on the percentage of TestSubject, in this case its puts TestSubject.percent #=> 90

This means that this specific name has a 90% chance of being pushed to the array. How ever I am not sure how to write that in ruby syntax.

Any ideas?

解决方案

arr.push(TestSubject.name) if rand(100) <= TestSubject.percent
