Rails 7.1: guide with ActiveRecord not properly handling JSONB column updates in PostgreSQL
I'm updating my dependencies and I'm working on a personal project and I'm working through a tutorial and I've tried everything I can think of but I'm wondering if anyone has experience with I'm stuck on something that should probably be simple... I'm experiencing a strange scenario with updating a JSONB column in Rails 7.1 using ActiveRecord. I have a model `User` with a `settings` JSONB column in a PostgreSQL database. When I try to update a specific key within this JSONB column, the entire column gets overwritten instead of just the key I intended to modify. Here’s the relevant part of my model: ```ruby class User < ApplicationRecord # Assuming settings is a JSONB column serialize :settings, JSON end ``` And here is the code where I attempt to update the `settings`: ```ruby user = User.find(params[:id]) user.settings['notification_preferences'] = { email: true, sms: false } user.save ``` After running this, I expected only the `notification_preferences` key to be updated within the `settings` column. However, when I inspect the `settings` field in the database, I see that it is entirely replaced by just this new hash, rather than merging the new key into the existing data. I’ve also tried using `update_column` like this: ```ruby user.update_column(:settings, user.settings.merge('notification_preferences' => { email: true, sms: false })) ``` This approach throws an behavior: `ActiveRecord::StatementInvalid: PG::UndefinedColumn: behavior: column "settings" does not exist` even though `settings` is indeed a JSONB column. I checked the database schema, and it clearly shows that the `settings` column exists as JSONB. I've also confirmed that there are no callbacks or validations interfering with the save operation. Is there a special way to handle updates for JSONB columns in Rails 7.1? Am I missing something in my ActiveRecord commands, or is there a known scenario with how Rails interacts with JSONB in the current version? I'd really appreciate any guidance on this. I'm open to any suggestions. I recently upgraded to Ruby stable. Any pointers in the right direction? I recently upgraded to Ruby 3.9. Any help would be greatly appreciated! The project is a application built with Ruby. Any examples would be super helpful.
