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

hash, ruby

Solution

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

Problem

Sorry if this obvious, I'm just not getting it. If I have an array of hashes like: ``` people = [{:name => "Bob", :occupation=> "Builder"}, {:name => "Jim", :occupation => "Coder"}] ``` And I want to iterate over the array and output strings like: "Bob: Builder". How would I do it? I understand how to iterate, but I'm still a little lost. Right now, I have: ``` people.each do |person| person.each do |k,v| puts "#{v}" end end ``` My problem is that I don't understand how to return both values, only each value separately. What am I missing? Thank you for your help.
