DeviseVerifiable

DeviseVerifiable adds a second step to registration process.

This is useful to register users with additional information or verify the users identity through a third-party service such as BlockScore.

Simply add DeviseVerifiable to your application's Gemfile:

gem 'devise'
gem 'devise-verifiable'

DeviseVerifiable adds a configuration variable called fields_for_verification. It configures which fields will be filled in the verification step:

Devise.setup do |config|
  config.fields_for_verification = [:full_name, :address]
end

To include DeviseVerifiable in a model, add the verifiable module to Devise modules:

class User < ActiveRecord::Base
  devise :database_authenticatable, :registerable, :verifiable
end

If you have multiple models configured with devise, define the fields for verification individually using the verify_fields method:

class User < ActiveRecord::Base
  devise :database_authenticatable, :registerable, :verifiable

  verify_fields :full_name, :address
end

To restrict unverified users from access certain pages, use the helper :authenticate_verified_user!:

class HomeController < ApplicationController
  # Only verified users will have access to home controller actions
  before_action :authenticate_verified_user!

  # ...
end

DeviseVerifiable will add some methods to your model:

#verified? -> this method will check if all fields used for verification are filled.

user = User.new

user.verified? # => false

user.full_name = 'Rodrigo Ra'
user.address = '555, Atomic Avenue'

user.verified? # => true

#valid_for_verification? -> this method will validate all fields used for verification and add errors messages for invalid fields. By default, it verifies if the fields are blank?

user = User.new

user.valid_for_verification? # => false
user.errors # => # <ActiveModel::Errors:0x007fe372bcc200 @base=...,
                 # @messages={:full_name=>["can't be blank"],
                 #            :address=>["can't be blank"]}>

user.full_name = 'Rodrigo Ra'
user.address = '555, Atomic Avenue'

user.valid_for_verification? # => true
user.errors.empty? # => true

#validate_for_verification -> You can customize the validation for fields.

Let's say that you need validate the zip_code:

class User < ActiveRecord::Base
  devise :database_authenticatable, :registerable, :verifiable

  verify_fields :full_name, :address, :zip_code

  protected
    def validate_for_verification(field)
      if field == :zip_code
        # custom validation for zip_code
      else
        super
      end
    end
end

To use a third-party service to verify the user identity.

To customize the verification view, following the devise conventions, create a file in app/views/devise/verification called new.html.erb.

First, configure which controller you want to use in config/routes.rb:

devise_for :users, controllers: { verification: :custom_verification }

And create it (in this example, CustomVerificationController):

class CustomVerificationController << Devise::VerificationController

  def new
  end

  def create
  end

end

This app exemplifies the usage of this gem.
