Ruby Rails User's Email Being overwritten - ruby-on-rails

Question

Playing around with authentication from scratch and for some reason my users email address is not being saved to the DB. When I fire up the console and pull a random user, their email is always nil, but have validations set for the presence of email and am get a successful user created message. This was working before and not sure what broke it. I know this is something super simple but it has got me for the last few hours and am hoping a second pair of eyes can tell me what I'm doing wrong. GitHub link below

Answer 1

Remove the email from the attr_acessor (here).
attr_accessor creates the getters and setters for all attributes listed there. So, basically, you're overriding these methods for the email attribute.
About the validation, use this:
validates :email, presence: true, uniqueness: true
