I have an array, each of whose elements is a hash with three key/value pairs:
:phone => "2130001111", :zip => "12345", :city => "sometown"
I'd like to sort the data by zip
so all the phone
s in the same area are together. Does Ruby have an easy way to do that? Can will_paginate
paginate data in an array?

Simples:
Note:
When using
sort_by
you need to assign the result to a new variable:array_of_hashes = array_of_hashes.sort_by{}
otherwise you can use the "bang" method to modify in place:array_of_hashes.sort_by!{}
