attr_json VS store_attribute

https://github.com/jrochkind/attr_json (by me)

I myself maintain one solution meant for rails attributes stored in a json column, at https://github.com/jrochkind/attr_json

One of these two should do the trick: https://github.com/jrochkind/attr_json https://github.com/DmitryTsepelev/store_model

I also have a similar "competing" in some ways gem at: https://github.com/jrochkind/attr_json

Some relational databases like Postgres and MySQL support JSON columns. This is useful if, for example, you want to create an ecommerce application with a products table with many variations - what is called Single Table Inheritance (STI). You can have some regular columns for the common attributes, and a JSON column for the specific ones.

If your app is built with Rails, you can use this library to help you on that (I'm not affiliated with it): https://github.com/jrochkind/attr_json

There are some other gems that can do similar things (each with somewhat different design and possibilities) including https://github.com/madeintandem/jsonb_accessor , https://github.com/DmitryTsepelev/store_model , and https://github.com/palkan/store_attribute

There is a store_accessor extension which adds types and works similar to Rails' attribute: https://github.com/palkan/store_attribute
