I have a json array that i get back from an api (sample below) . say I want to sort the data based on age, and also select first 5 of them, how can I do this in ruby?
[
{"name":"Richard", "email":"[email protected]", "age" : "32"},
{"name":"Bob", "email":"[email protected]", "age" : "52"},
....
]
Let's say your array
arr=[
{"name"=>"Richard", "email"=>"[email protected]", "age" => "32"},
{"name"=>"Bob", "email"=>"[email protected]", "age" => "52"},
{"name"=>"Bob", "email"=>"[email protected]", "age" => "21"},
{"name"=>"Bob", "email"=>"[email protected]", "age" => "58"},
{"name"=>"Bob", "email"=>"[email protected]", "age" => "45"},
{"name"=>"Bob", "email"=>"[email protected]", "age" => "67"},
{"name"=>"Bob", "email"=>"[email protected]", "age" => "92"}
]
Code
p arr.sort_by{|h|h['age']}.first(5)
#=>[{"name"=>"Bob", "email"=>"[email protected]", "age"=>"21"}, {"name"=>"Richard", "email"=>"[email protected]", "age"=>"32"}, {"name"=>"Bob", "email"=>"[email protected]", "age"=>"45"}, {"name"=>"Bob", "email"=>"[email protected]", "age"=>"52"}, {"name"=>"Bob", "email"=>"[email protected]", "age"=>"58"}]
