ActiveRecord

# app/models/user.rb
class User < ApplicationRecord

  include RailsJwtAuthOmniath::Omniauthable

  validates :email, presence: true,
                    uniqueness: true,

  validates :email, presence: true,
                    uniqueness: true,
                    format: URI::MailTo::EMAIL_REGEXP
end

Omniauth

Allow you to use omniauth providers to login in the platform. Rails_jwt_auth_omniauth will not save auth_token from providers and only will create a jwt session.

To configure omniauth clients:

Select a provider and define it in your Gemfile and install:

# Gemfile
gem 'omniauth' # Required if omniauth is not dependency in your provider gem
gem 'omniauth-google-oauth2'

Configuration providers:

# config/initialize/rails_jwt_auth_omniauth.rb
RailsJwtAuthOmniauth.setup do |config|
  # ...
  config.omniauth :google_oauth2, ENV['GOOGLE_CLIENT_ID'], ENV['GOOGLE_CLIENT_SECRET'], {
    provider_ignores_state: true, # this is neccesary for CSRF in extenals requests
    scope: 'userinfo.email, userinfo.profile'
  }
  # You can add multiple omniauth configurations of each provider
end

In router:

#cofig/router.rb
post '/auth/:provider/callback', to: 'rails_jwt_auth_omniauth/omniauths#callback' # If not use generator

In model:

include RailsJwtAuthOmniauth::Omniauthable
def self.from_omniauth(auth)
  # Define logic to search or create User. This method should return a user to be logged
  # auth.provider: provider that has processed request
  # auth['info']: User data from provider
end

In js you will need a library to get auth_code from provider to pass the code to the backend:

  // Ej: vue-google-oauth2
  const authCode = await this.$gAuth.getAuthCode()
  const response = await this.$http.post(
    'http://yout-backend-server-api/auth/google_oauth2/callback',
    { code: authCode }
  )

Locales

Copy config/locales/en.yml into your project config/locales folder and edit it.
