Convert Array / Hash in YAML to Ruby on Rails

Question

I want to build the following YAML formatting from an array / hash:

Name: gender: - female nationality: - german - danish 

Now I have such an array:

 names = ["Abbie", "Abeline", "Abelone"] 

What would be the easiest way to get from this array to YAML?

I tried converting it to a hash by adding values ​​for gender and nationality:

 names.each do |name| (META_HASH ||= Hash.new) = name => { gender: 'female', nationality: ['german', 'danish'] } end 

This, however, just gives me a syntax error. Any help in converting this would be much appreciated!
