json_serialize gives you the ability to JSON-encode data into ActiveRecord
model fields. JSON is a more compact but less robust serialization than YAML.
Only hashes, arrays, and primitives can be reliably encoded to database fields;
other types may not decode properly or at all.
Firstly, add the gem to your Rails project's Gemfile:
gem 'json_serialize'Then, include into your model the JsonSerialize module, and call the
json_serialize method to indicate which fields should be serialized:
class MyModel < ActiveRecord::Base
include JsonSerialize
json_serialize :favorites, :preferences
endMore information can be found at the {JsonSerialize::ClassMethods#json_serialize} method documentation.
