Ruby根据属性在数组中查找并返回对象 [英] Ruby find and return objects in an array based on an attribute

问题描述

如果某个属性正确，如何遍历对象数组并返回整个对象?

How can you iterate through an array of objects and return the entire object if a certain attribute is correct?

我的Rails应用程序中有以下内容

I have the following in my rails app

array_of_objects.each { |favor| favor.completed == false }

array_of_objects.each { |favor| favor.completed }

但是由于某种原因，这两个返回相同的结果！我试图用collect，map，keep_if以及!favor.completed而不是favor.completed == false替换each，但它们都不起作用！

but for some reason these two return the same result! I have tried to replace each with collect, map, keep_if as well as !favor.completed instead of favor.completed == false and none of them worked!

我们非常感谢您的帮助！

Any help is highly appreciated!

推荐答案

array_of_objects.select { |favor| favor.completed == false }

将返回所有已完成的对象为false.

Will return all the objects that's completed is false.

您也可以使用find_all代替select.
