在Rails中按字母顺序排序 [英] Sort alphabetically in Rails

问题描述

如何按Rails(字母顺序)对数组进行排序.我已经尝试过:

How do I sort an array in Rails (alphabetical order). I have tried:

sort_by(&:field_name) 

这给了我一个包含大写字母顺序和小写字母顺序的数组.我已经尝试过:

which that gives me an array with capital letter order and then lower case order. I have tried:

array.sort! { |x,y| x.field_name.downcase <=> y.field_name.downcase }

有什么办法解决这个问题?

Is there any way to solve this?

推荐答案

您应该首先将每个字符串都转换为小写字母，然后进行如下排序:

You should first downcase every string and then sort like:

array = ["john", "Alice", "Joseph", "anna", "Zilhan"]
array.sort_by!{ |e| e.downcase }
=> ["Alice", "anna", "john", "Joseph", "Zilhan"]
