Conditional key/value in a ruby hash

Question

Is there a nice (one line) way of writing a hash in ruby with some entry only there if a condition is fulfilled? I thought of

{:a => \'a\', :b => (\'b\         


        

Answer 1

My one-liner solution:

{:a => 'a'}.tap { |h| h.merge!(:b => 'b') if condition }
