Convert nested JSON object to nested OpenStructs

If you are parsing a nested JSON string such as this:

{
   "vendor": {
       "company_name": "Basket Clowns Inc",
       "website": "www.basketthecloon.com"
 }

And want to access it with dot notation, simply doing:

OpenStruct.new(JSON.parse(json_str))

will not do!

Turns out there is a cool option on JSON.parse called object_class:

JSON.parse(json_str, object_class: OpenStruct)

Now you can access the resulting object with dot notation all the way down:

obj.vendor.website #=> "www.basketthecloon.com"
