rememberable | Query caching for Laravel | Database library

Here is my user model

To start, I may be using the wrong callback for what I'm trying to do

and/or there may be a better "Rails Way" to accomplish this. If so, I'm all ears.

I've been referencing api.rubyonrails.org/v7.0.1/classes/ActiveRecord/Callbacks/ClassMethods

and

guides.rubyonrails.org/active_record_callbacks.html#creating-an-object

I need to implement:

"user sign up creates an account associated with user as owner"

(ultimately, user will belong_to account, and account will has_many users)

Accounts in database schema have name:string and owner_id:integer

Currently, I'm not able to access the newly created User, and the Account is not being created. I think I'm very close though.

current models/user.rb:

I am new to development on rails. I need help with customizing the device. I have user with polymorphic association - profilable. When registering, I need to fill in the profilable depending on the selected radio button.

I use Windows10+Ubuntu18.04

I set "has_many" in a model, but an error message appears when I start the rails console:

CONTEXT

I'm using devise_invitable to allow a user (with an admin role) to register another user in my app.

User objects have an email, password, token (random string), role (also string) and an associated HealthRecord object which has name, last name, dni (personal id) plus some extra info

PROBLEM

For some reason, when I input an existing email, I get an error (which is intended validation) but it also destroys the HealthRecord associated with the user who has that existing email.

CODE

This is what my console shows upon trying to create the user with existing email

So I have a devise model User, and I added some fields to it like username, address, and so on. The model looks like this:

In my app I created friend list for User. Inside Friend model I have validations for unique connection between users. Everything works good, but I don't know how to write tests for this model. It's looks like that:

Friend.rb

I am trying to learn Ruby on Rails by building a small web application. My first step was to start with OAuth login so users could login using Facebook, Google etc. But when I go to the /users/sign_up devise page on my localhost and click on Sign in with GoogleOauth2, it "does nothing" and the console tells me:

In a Rails 5 application, I have a shortlist model in a HABTM relationship with a user model, with the users controlled by Devise. This is all working as expected, where each User can see their own Shortlists (only).
