You can pass an object_class to JSON.parse which will use that class to create an object. Can pass OpenStruct to create a simple object or something like an ActiveRecord class.

json_data = '{"id": 1,"name": "A green door","price": 12.50,"tags": ["home", "green"]}'

parsed_json = JSON.parse(json_data, object_class: OpenStruct)

p parsed_json.name
# "A green door"

.find_by will return a nil when record isn’t found. .find_by! will return ActiveRecord::RecordNotFound.
