How To Convert A Hash To A Struct In Ruby

Posted by Weston Ganger on January 24, 2017

I needed a simple way to convert a hash into a Struct in my Rails app. It wasn’t readily obvious how to do so but the answer is pretty simple.

h = {name: 'Foobar', description: 'test'}


You could take this one step further and create a monkey patch like below if your using this method often:

Hash.class_eval do
  def to_struct(h)


My ruby gem rearmed-rb provides this monkey patch and many others. It is a collection for helpful methods and monkey patches that can be safely applied on an opt-in basis.
