How to sort an array of hashes in ruby

Question

I have an array, each of whose elements is a hash with three key/value pairs:

:phone => \"2130001111\", :zip => \"12345\", :city => \"sometown\"
         


        

Answer 1

If you have Nested Hash (Hash inside a hash format) as Array elements (a structure like the following) and want to sort it by key (date here)

data =  [
    {
        "2018-11-13": {
            "avg_score": 4,
            "avg_duration": 29.24
        }
    },
    {
         "2017-03-13": {
            "avg_score": 4,
            "avg_duration": 40.24
        }
    },
    {
         "2018-03-13": {
            "avg_score": 4,
            "avg_duration": 39.24
        }
    }
]

Use Array 'sort_by' method as

data.sort_by { |element| element.keys.first }
