User session isn't being created, any idea why not? - ruby-on-rails

Question

I'm using a customised devise sessions controller to manage my user sessions, however whenever I try sign in as an existing user, my log in functionality doesnt work, it just returns the sign in form, and the server returns this message:

My Sessions Controller looks like this:
class Users::SessionsController < Devise::SessionsController
before_action :configure_sign_in_parameters
def new
super
end
def create
#user = User.find_by(cell_number: params[:user][:cell_number])
super
end
private
def after_sign_in_path_for(resource)
root_path
end
def configure_sign_in_parameters
devise_parameter_sanitizer.for(:sign_in).push(:cell_number, :password)
end
end
My routes look like this:
Rails.application.routes.draw do
### Admin
devise_for :admin_users, ActiveAdmin::Devise.config
ActiveAdmin.routes(self)
### User
devise_for :users, controllers: { :registrations => "users/registrations",
:sessions => "users/sessions",
:passwords => "users/passwords" }
devise_scope :user do
namespace :vodacom do
namespace :users do
get "/register", to: 'registrations#new'
get "/create", to: 'registrations#create'
end
end
end
end
And my sign in form looks like this:
h2 Normal Log in
= simple_form_for #user, url: user_session_path(#user) do |f|
div class="form-inputs"
= f.input :cell_number, required: true, autofocus: true
= f.input :password, required: true
= f.input :remember_me, as: :boolean if devise_mapping.rememberable?
div class="form-actions"
= f.button :submit, "Log in"
Any clue what i'm doing wrong? My application controller specifies that a user should be authenticated before any action.

Answer 1

I figured out what I was doing wrong, my user model does not have an email attribute, rather it has a cell_number attribute. So since i'm using devise, devise defaults "email" as the authentication key for the model. In order to fix this i had to specify cell_number as an authentication key in my User model:
devise :database_authenticatable,
:registerable,
:recoverable,
:rememberable,
:registerable,
:authentication_keys => [:cell_number]
