Hi, I'm Chris. I'm the creator of GoRails, Hatchbox.io and Jumpstart. I spend my time creating tutorials and tools to help Ruby on Rails developers build apps better and faster.

About This Episode

When you receive a JSON response from an API endpoint, it's really easy to convert this to a Ruby hash. But hashes don't feel very Ruby-ish when you're working with them and you can't add methods and treat them like objects.


This is where OpenStruct comes in. We can parse the JSON and then create OpenStruct objects so users can interact with the API responses just like they're used to with database records and other objects.

Plus, OpenStruct allows us to handle changes for API version responses without modifying our code. Now that is a win in my book.
