JSON QUERY INSIDE WHERE RAILS UPDATE
# app/controllers/books_controller.rb class BooksController < ApplicationController def update UpdateBookPayload. It is as simple as any other column types. Let's start our journey! (I use Rails API-only as example, but this article can be implemented in normal Rails as well) The advantage of using jsonb is that you can easily integrate relational and non-relation data, with performance that can be better than most non-relational databases like MongoDB. I recommend to use JSONB instead of JSON, as JSONB column type is the upgraded version of JSON. They are look the same, but there are many differences, especially in functionality. PostgreSQL has JSON and JSONB column type. This is the first time I'll deep dive into a topic. I have to read many articles before I can perform well. Besides, we still want to clump all objects together into a list of JSON objects, not a list of Strings representing JSON objects. Even the existing articles did not cover in details. Adding a cast to the view query, changing the column type to text or varchar, is a possible solution, yet it's useful to have the data as a structured object in Rails. If you continue to read this article, I assume that you know Ruby, OOP in Ruby, RoR, and Active Record.
