Rails 4.2 enum not working

I am trying to use rails enum fields for the user status functionality in my app however enums don't seem to be working(I have used Devise to manage the user login, registration .etc).
this is the result in my rails console where the status appears as

instead of

user = User.first User Load (1.6ms) SELECT "users".* FROM "users" ORDER BY "users"."id" ASC LIMIT 1
=> #<User id: 1, email: "", encrypted_password:
reset_password_token: nil, reset_password_sent_at: nil,
remember_created_at: nil, sign_in_count: 1, current_sign_in_at:
"2016-06-10 22:57:03", last_sign_in_at: "2016-06-10 22:57:03",
current_sign_in_ip: "::1", last_sign_in_ip: "::1", created_at:
"2016-06-10 22:57:03", updated_at: "2016-06-11 10:59:41", first_name:
"John", last_name: "Smith", phone: nil, **status: 0**>

but I have declared the status enum in my user.rb

class User < ActiveRecord::Base
# Include default devise modules. Others available are:
# :confirmable, :lockable, :timeoutable and :omniauthable
devise :database_authenticatable, :registerable,
:recoverable, :rememberable, :trackable, :validatable

enum status: [:pending, :active, :suspended]

and here is my migration

class AddStatusColumn < ActiveRecord::Migration
def change
add_column :users, :status, :integer, default: 0

Furthermore, when I use
(default) I get an error "undefined method `pending?'" for instance

irb(main):014:0> user.pending?
NoMethodError: undefined method `pending?' for #<User:0x315dba8>

from bin/rails:4:in `<main>'

how do I fix this issue with rails enum?

You need to reload or restart the Rails console when you change code in the application.

Depending on the type of change the faster reload might solve your problem:

> reload!

On bigger changes: When you added or removed gems or change code outside of the app folder (for example a initializer or something in the lib folder) you will need to exit and restart the console completely:

> exit
$ rails console
