User_id and user_type is NULL using gem audited

Question

I have a problem with an audited gem. It's two problems in one. I installed and configured the audited gem in my application, but when I delete the database and run migrate and seed again, the user_id and user_type fields in the database are NULL in addition, when I register a user through devise sign_up (new_registration_path) the user_id and user_type are also registered as NULL in the database, which causes an error, as can be seen in the image or here:

undefined method `name' for nil:NilClass

The error line is this:

<%= f.select :user_name_cont, Audity.all.map { |u| [u.user.name] }.uniq, include_blank: true %>

I already put in my Audity model a belongs_to optional: true, but still the error continues.

My application is on my github: https://github.com/eltonsantos/auth-rails

How do I resolve this error? The solution I think is when running the seed or registering a new user, run an after_save or an after_create putting some default id in the user_id field (maybe his own id), but I'm not sure if it's the best solution.

Answer 1

I pulled your rails app and ran the database seed. The error disappeared for me after fixing a typo in your user.rb file.

class User < ApplicationRecord

  audited
  # Include default devise modules. Others available are:
  # :confirmable, :lockable, :timeoutable, :trackable and :omniauthable
  devise :database_authenticatable, :registerable,
         :recoverable, :rememberable, :validatable

  enum role: { superadmin: 0, auditor: 1, manager: 2, registred: 3 }

  has_many :cars

  has_one_attached :avatar # removed a comma here

end

Let me know if that resolves the issue for you also.

Boa sorte!
