Using with Mongoid

My example use mongoid and custom sms provider. For my case I had to make it more in JS with manual validations so this may not be for you. Take a closer look to Model and Controller on how active_model_otp is used.

Model

  require "active_model_otp"
  class User
    include Mongoid::Document
    ...
    include ActiveModel::OneTimePassword 
    ...
    has_one_time_password
    ...
    field :email
    field :otp_secret_key 

##Controller def check_verification_code data = {:result => false} if current_user.authenticate_otp(params[:verification_code], drift: 200) #drift enough for old users data = {:result => true} session[:mobile_verified] = true end respond_to do |format| format.json { render :json => data} end end

    def sendverification
      data = {:result => false} 
      phone = validate_phone(params[:verification_phone])
      if phone.present?
        sms = Sms.new       
        if sms.send_sms([phone],APP_CONFIG.sms_from, t('verification_message') + current_user.otp_code.to_s)
          data = {:result => true} 
        end
      end
      respond_to do |format|
        format.json  { render :json => data} 
      end
    end
    
    
    
    def create 
    ...
    if session[:mobile_verified] = true
      @provider.mobile_verified = true
      @provider.business_phone = validate_phone( params[:provider][:business_phone])
      session[:mobile_verified] = false
    else
    ...

##View(in HAML)

  = bootstrap_form_for @provider, id: @provider.id,  validate: true  do |f|
    .span{style: 'text-align: center'} 
      %h4= t('.provider_exp')
      %h5= t('.provider_exp1')
      #phone_details
        = f.label :mobile_phone, class: 'control-label', id: 'verify_phone_label'
        = f.default_tag :text_field, :verification_phone, placeholder: '05XX XXXXXXX', id: 'verification_phone' ,:class => "{mask:'(0569) 9999999'}", :alt=> "(0569) 9999999'"     
        = button_to t('.send_code'), "#", :id=> 'sendverification', :class=> 'btn btn-medium btn-success'
        = f.label :error_mobile_label, class: 'control-label', id: 'error_mobile_label' 
      %hr
      #verification_details
        = f.label :info_label, class: 'control-label', id: 'verify_code_label' , style:"display:none"
        = f.default_tag :text_field, :verification_code, placeholder: 'XXXXXX', id: 'verification_code' ,:class => "{mask:'999999'}", :alt=> "999999'" 
        = f.label :error_label, class: 'control-label', id: 'error_code_label' 
        = f.label :success_label, class: 'control-label', id: 'success_code_label'
