to_struct method for Ruby hashes

 / Published in: Ruby
 

URL: http://rubyforge.org/snippet/detail.php?type=snippet&id=1

A very useful snippet found in this thread.

However it does not do deep conversion, that is, for a hash of hashes, you will get back a struct of hashes.

  1. class Hash
  2.    def to_struct
  3.       Struct.new(*keys).new(*values)
  4.    end
  5. end
  6.  
  7.  
  8. # then use it like this
  9.  
  10. h = {:foo => 'bar', :baz => 'boz'}
  11.  
  12. s = h.to_struct("NameOfMyStruct")
