Can't disable validation of email in devise-auth-token - ruby-on-rails

Question

I am using devise-auth-token and want to sign in with field another than email.
So I used phone_number instead and everything is working properly but I can't remove validation on email, here are my codes
user.rb
class User < ActiveRecord::Base
include DeviseTokenAuth::Concerns::User
devise :database_authenticatable, :confirmable, authentication_keys: [:phone_number]
mount_uploader :avatar, AvatarUploader
validates :first_name, presence: true,format: {with: /[[:word:]]/}
validates :last_name , presence: true,format: {with: /[[:word:]]/}
validates :email , format: { with: /\A([^#\s]+)#((?:[-a-z0-9]+\.)+[a-z]{2,})\z/i, on: :create }, uniqueness: true
validates :phone_number, presence: true, uniqueness: true
validate :birthdate_in_the_future_invalid
validates :country_code, presence: true
validates :birthdate, presence: true
validates :gender, presence: true
# validates :file, presence: true
validates :phone_number, phone: { possible: true, types: [:mobile], country_specifier: -> phone { phone.country_code.try(:upcase) } }
validate :e164_phone_number
after_create :set_provider_uid
def email_required?
false
end
def email_changed?
false
end
def password_required?
super if confirmed?
end
def password_match(password, password_confirmation)
self.errors[:password] << "can't be blank" if password.blank?
self.errors[:password_confirmation] << "can't be blank" if password_confirmation.blank?
self.errors[:password_confirmation] << "does not match password" if password != password_confirmation
password == password_confirmation && !password.blank?
end
private
def birthdate_in_the_future_invalid
begin
if Date.strptime(birthdate, '%d-%m-%Y') > Date.today
errors.add(:birthdate, "in_the_future")
end
rescue
errors.add(:birthdate, "invalid format")
end
end
def e164_phone_number
if phone_number[0] != '+'
errors.add(:phone_number, "invalid format")
end
end
def set_provider_uid
self.update_column(:uid, phone_number)
self.update_column(:provider, "phone_number")
end
end
and this is my initializers/devise.rb
Devise.setup do |config|
config.mailer_sender = 'aliabdelrahmanweka74#gmail.com'
require 'devise/orm/active_record'
config.authentication_keys = [:phone_number]
config.case_insensitive_keys = [:phone_number]
config.strip_whitespace_keys = [:phone_number]
config.skip_session_storage = [:http_auth]
config.stretches = Rails.env.test? ? 1 : 11
config.reconfirmable = false
config.expire_all_remember_me_on_sign_out = true
config.password_length = 6..128
config.email_regexp = /\A[^#\s]+#[^#\s]+\z/
config.reset_password_within = 6.hours
config.sign_out_via = :delete
end
I used funciton email_required? and make it return false but nothing happens
I call localhost:3000/users , Method Post
params:
{
"user": {
"first_name": "ali",
"last_name": "weka",
"gender": "male",
"birthdate": "25-06-2016",
"email": "",
"phone_number": "[phone]",
"country_code": "EG",
"uid": "[phone]",
"provider": "phone_number"
}
}
and here's the response
{"status":"error","data":{"id":null,"first_name":"ali","last_name":"ali","country_code":"EG","phone_number":"[phone]","gender":"male","birthdate":"25-06-2016","created_at":null,"updated_at":null,"provider":"email","uid":"[phone]","avatar":{"url":null},"email":""},"errors":{"email":["can't be blank","is invalid"],"full_messages":["Email can't be blank","Email is invalid"]}}
so any help, please?

Answer 1

I had the same problem. I wanted some users with email, and some without.
Solution
You should first remove the null: false restriction from users table with a migration. Should you want to remove the default "", do it to. Don't remove the index, so it still validates that emails are unique (in case you still use emails sometimes). Null values won't have a problem with the unique constraint.
If you are using devise validatable, add this method in your User model:
def email_required?
false
end
After doing the previous part, you should do one of the following:
Option 1:
Going deep into devise_token_auth gem, at least in my case, I realized that this concern was being included.
It's included by default unless you modify the DeviseTokenAuth initializer with
config.default_callbacks = false
But maybe you don't want that.
Option 2:
If you check the code in the concern I linked, you can see that it validates email in case the provider of the user is 'email'.
The fix in my case was to change the provider field to something else for the users that didn't have email.
With any of those 2 changes, your email won't be validated anymore.
For somebody who needs email sometimes:
Of course, do what Devise wiki says
apart from the other field include email in case_insensitive_keys, strip_whitespace_keys
and you can have a method in the User model with:
def email_required?
true unless phone_number?
end
