How do I search within an array of hashes by hash values in ruby?

Question

I have an array of hashes, @fathers.

a_father = { \"father\" => \"Bob\", \"age\" =>  40 }
@fathers << a_father
a_father = { \"father\" => \"Da         


        

Answer 1

(Adding to previous answers (hope that helps someone):)

Age is simpler but in case of string and with ignoring case:

• Just to verify the presence:

@fathers.any? { |father| father[:name].casecmp("john") == 0 } should work for any case in start or anywhere in the string i.e. for "John", "john" or "JoHn" and so on.

• To find first instance/index:

@fathers.find { |father| father[:name].casecmp("john") == 0 }

• To select all such indices:

@fathers.select { |father| father[:name].casecmp("john") == 0 }
