How do I search within an array of hashes by hash values in ruby?
You're looking for Enumerable#select (also called find_all
):
@fathers.select {|father| father["age"] > 35 }# => [ { "age" => 40, "father" => "Bob" },# { "age" => 50, "father" => "Batman" } ]
Per the documentation, it "returns an array containing all elements of [the enumerable, in this case @fathers
] for which block is not false."
if your array looks like
array = [ {:name => "Hitesh" , :age => 27 , :place => "xyz"} , {:name => "John" , :age => 26 , :place => "xtz"} , {:name => "Anil" , :age => 26 , :place => "xsz"} ]
And you Want To know if some value is already present in your array. Use Find Method
array.find {|x| x[:name] == "Hitesh"}
This will return object if Hitesh is present in name otherwise return nil
