ruby rails activerecord validation

I just started working with I've spent hours debugging this and Quick question that's been bugging me - I'm experiencing an unexpected behavior when trying to implement custom validation callbacks in my Rails 7.1 application. I have a model, `User`, where I'm trying to validate the `email` field by checking its format and ensuring it is unique. However, my custom validation method seems to be bypassed entirely when I attempt to create a new user record with a valid email. Here’s the code snippet for the model: ```ruby class User < ApplicationRecord validates :email, presence: true, uniqueness: true, format: { with: URI::MailTo::EMAIL_REGEXP } validate :custom_email_validation private def custom_email_validation if email.present? && !email.end_with?('@example.com') errors.add(:email, 'must be from the example.com domain') end end end ``` Despite this, when I create a user like so: ```ruby User.create(email: 'test@domain.com') ``` I do not see any validation errors being raised, and the record is being saved to the database. I expect the `custom_email_validation` method to trigger and add an behavior, but it seems like the custom validation is never invoked. I’ve tried putting `puts` statements inside the `custom_email_validation` method, but they do not output anything when I run my tests. I've also checked for any callbacks that might interfere with the validation process, but I need to find any. To debug, I attempted to isolate the validation by temporarily removing the other validations, but the question continues. Am I missing something that could prevent this custom validation from executing? Any insights would be greatly appreciated! How would you solve this? I'd be grateful for any help. This is part of a larger microservice I'm building. Thanks for any help you can provide!
