How do I iterate over an array of hashes and return the values in a single string?

Question

Sorry if this obvious, I\'m just not getting it. If I have an array of hashes like:

people = [{:name => \"Bob\", :occupation=> \"Builder\"}, {:name =&         


        

Answer 1

Here you go:

puts people.collect { |p| "#{p[:name]}: #{p[:occupation]}" }

Or:

people.each do |person|
  puts "#{person[:name]}: #{person[:occupation]}"
end

In answer to the more general query about accessing the values in elements within the array, you need to know that people is an array of hashes. Hashes have a keys method and values method which return the keys and values respectively. With this in mind, a more general solution might look something like:

people.each do |person|
  puts person.values.join(': ')
end
