If we have to don our wizarding hat and take out our crystal balls, we would still be harping that Ruby on Rails is going to be hot in 2026 too! 2026 is also going to bring in only 24 hours a day (how we wish, we could stretch the time) and time would still spell money for businesspeople. When time is money, anything which can save time is gold! And that\u2019s where Ruby on Rails come in picture. What could take other programming languages months to complete, takes only weeks, sometimes just days for Ruby on Rails. Shaping ideas into applications was never so easy. With Ruby on Rails, agility is the norm and convention over configuration the benchmark. And what make Ruby on Rails more powerful are the bunch of pre-packaged, categorized, reusable codes, named as gems. With gems, Rails is a super power to behold. One of the most popular gems is called as Devise Gems, which is a complete authentication package. Read on to know more about Devise gem.<\/p>\n

Introducing Devise for Ruby on Rails 8<\/b><\/h2>\n

Devise is a widely used authentication library for Ruby on Rails 8 applications, built on top of Warden<\/strong>, a Rack-based authentication framework.<\/p>\n

Warden manages user sessions by securely validating the identity of authenticated users. It also ensures that unauthenticated users are restricted from accessing protected routes and resources within a Rails application.<\/p>\n

Since Warden operates strictly at the Rack level, it does not provide Rails-specific features such as controllers, views, helpers, or configuration generators required for a complete authentication system. Devise bridges this gap by adding these Rails integrations, making it easier to implement a robust and production-ready authentication solution in Rails 8.<\/p>\n

A major advantage of Devise is its modular architecture. It includes around ten authentication modules that allow you to customize how authentication behaves in your application. You can enable only the modules you need\u2014such as Registerable, Omniauthable, Trackable, and others\u2014keeping your authentication setup clean and flexible.<\/p>\n

\u00a0<\/p>\n

With this understanding, we can now begin building our Tasks application and set up Devise in a Rails 8 environment.<\/p>\n

\u00bfQu\u00e9 es la gema 'Dise\u00f1ar'?<\/strong><\/h2>\n

<\/p>\n

<\/p>\n

    \n
  1. Devise es una soluci\u00f3n de autenticaci\u00f3n potente y flexible para Rails.<\/li>\n
  2. Est\u00e1 completamente basado en la estructura MVC.<\/li>\n
  3. Permite tener m\u00faltiples modelos registrados al mismo tiempo.<\/li>\n<\/ol>\n

    <\/p>\n

    <\/p>\n

    Diferentes m\u00f3dulos de dise\u00f1o<\/strong><\/h2>\n

    <\/p>\n

    <\/p>\n

    Devise se compone de 10 m\u00f3dulos importantes.<\/p>\n

    <\/p>\n

    <\/p>\n

      \n
    1. Base de datos autenticable: cifra y almacena contrase\u00f1as en la base de datos para que se pueda realizar la validaci\u00f3n de la autenticidad de un usuario en el momento de iniciar sesi\u00f3n. La autenticaci\u00f3n se puede realizar tanto a trav\u00e9s de solicitudes POST como de autenticaci\u00f3n b\u00e1sica HTTP.<\/li>\n
    2. Omniautable: Agregar\u00a0OmniAuth<\/a>\u00a0soporte, es decir, es posible configurar un inicio de sesi\u00f3n con OmniAuth.<\/li>\n
    3. Confirmable: env\u00eda correos electr\u00f3nicos con instrucciones de confirmaci\u00f3n y verifica si una cuenta ya est\u00e1 confirmada durante el inicio de sesi\u00f3n.<\/li>\n
    4. Recuperable: Restablece la contrase\u00f1a del usuario y env\u00eda instrucciones de restablecimiento.<\/li>\n
    5. Registrable: maneja el proceso de registro al registrar a los usuarios y tambi\u00e9n les permite editar y destruir su cuenta.<\/li>\n
    6. Recordable: como sugiere el nombre, ayuda a administrar, generar y borrar un token para recordar al usuario a trav\u00e9s de las cookies guardadas.<\/li>\n
    7. Rastreable: rastrea el recuento de inicios de sesi\u00f3n, las marcas de tiempo y la direcci\u00f3n IP.<\/li>\n
    8. Tiempo de espera<\/a>: caduca las sesiones que no han estado activas en un per\u00edodo de tiempo espec\u00edfico.<\/li>\n
    9. Validable: Proporciona validaciones de correo electr\u00f3nico y contrase\u00f1a. Es opcional y se puede personalizar, por lo que puede definir sus propias validaciones.<\/li>\n
    10. Bloqueable: ayuda a bloquear una cuenta despu\u00e9s de una cantidad espec\u00edfica de intentos fallidos de inicio de sesi\u00f3n. La cuenta se puede desbloquear por correo electr\u00f3nico o despu\u00e9s de un per\u00edodo de tiempo espec\u00edfico.<\/li>\n<\/ol>\n

      Instalar Devise, crear modelo, ver y configurar<\/strong><\/h2>\n

      <\/p>\n

      <\/p>\n

        \n
      1. Crea tu aplicaci\u00f3n Rails<\/li>\n
      2. Agregue la gema 'idear' a su Gemfile.<\/li>\n
      3. Ejecute la instalaci\u00f3n del paquete en su l\u00ednea de comando.<\/li>\n
      4. Ejecute Rails Genere Devise:install en su l\u00ednea de comando.<\/li>\n
      5. Execute rails generate devise <Model Name> in your command line to create model<\/li>\n<\/ol>\n
        \n
        Run the following command:<\/b><\/div>\n
        \u00a0<\/div>\n
        rails generate devise User<\/pre>\n
        After running this command, a user.rb model will be generated in the app\/models directory.<\/div>\n
        \u00a0<\/div>\n
        class User < ApplicationRecord\n  # Include default Devise modules.\n  # Other available modules are:\n  # :confirmable, :lockable, :timeoutable, and :omniauthable
        \u00a0 devise :database_authenticatable,
        \u00a0 \u00a0 \u00a0 \u00a0 \u00a0:registerable,
        \u00a0 \u00a0 \u00a0 \u00a0 \u00a0:recoverable,
        \u00a0 \u00a0 \u00a0 \u00a0 \u00a0:rememberable,
        \u00a0 \u00a0 \u00a0 \u00a0 \u00a0:trackable,
        \u00a0 \u00a0 \u00a0 \u00a0 \u00a0:validatable
        fin<\/pre>\n<\/div>\n
          \n
        1. Si lo desea, puede modificar su archivo de migraci\u00f3n para el usuario. Luego ejecuta rake db:migrate<\/li>\n
        2. Ejecute Rails y genere devise:views en su l\u00ednea de comando para crear vistas<\/li>\n
        3. debe configurar las opciones de URL predeterminadas para el correo de Devise en cada entorno. Ex- configuraci\u00f3n para config\/environments\/development.rb: config.action_mailer.default_url_options = { host: 'localhost', puerto: 3000 }<\/li>\n<\/ol>\n
          <\/p>\n
          <\/p>\n
          Puede personalizar modelos, controladores y vistas seg\u00fan los requisitos. Siga los documentos de github para obtener m\u00e1s detalles.<\/p>\n
