<div class="my-6">
<p>Como ya saben, una de las funcionalidades nuevas de Rails 8 es el <strong>nuevo generador básico de autenticación</strong> que viene a demostrar que no es tan complejo desarrollar todo lo que respecta a autenticación en una aplicación con Rails y que muchas veces no es necesario depender de terceros (gemas). La discusión comenzó <a href="https://github.com/rails/rails/issues/50446">aquí</a>.</p>
<p>Dicho esto, veamos que pasa usando el generador en una aplicación API-Only:</p>
<div class="language-bash highlighter-rouge"><div class="highlight"><pre class="highlight"><code> rails <span class="nt">-v</span>

</code></pre></div></div>
<p>Y ejecutamos el nuevo comando:</p>
<div class="language-bash highlighter-rouge"><div class="highlight"><pre class="highlight"><code> rails g authentication

</code></pre></div></div>
<p>Ok, ahora por ejemplo, si revisamos <code class="language-plaintext highlighter-rouge">SessionsController</code> veremos que el método de <code class="language-plaintext highlighter-rouge">Login</code> se ve de la siguiente forma:</p>
<div class="language-ruby highlighter-rouge"><div class="highlight"><pre class="highlight"><code> <span class="k">def</span> <span class="nf">create</span>
<span class="k">if</span> <span class="n">user</span> <span class="o">=</span> <span class="no">User</span><span class="p">.</span><span class="nf">authenticate_by</span><span class="p">(</span><span class="n">params</span><span class="p">.</span><span class="nf">permit</span><span class="p">(</span><span class="ss">:email_address</span><span class="p">,</span> <span class="ss">:password</span><span class="p">))</span>
<span class="n">start_new_session_for</span> <span class="n">user</span>
<span class="n">redirect_to</span> <span class="n">after_authentication_url</span>
<span class="k">else</span>
<span class="n">redirect_to</span> <span class="n">new_session_url</span><span class="p">,</span> <span class="ss">alert: </span><span class="s2">"Try another email address or password."</span>
<span class="k">end</span>
<span class="k">end</span>
</code></pre></div></div>
<p>O sea, redirecciona a rutas y/o vistas que en nuestra API no existen ni hacen sentido, y además si inspeccionamos el metodo <code class="language-plaintext highlighter-rouge">start_new_session_for</code> nos daremos cuenta de que el sistema está basado 100% en <strong>autenticación mediante cookies</strong>. Entonces, ¿qué hacemos?</p>
<p>Mi propuesta es la siguiente: el generador crea las bases para la autenticación y creo que funciona bastante bien, por lo que con unas pequeñas modificaciones podemos dejar funcionando una <strong>autenticación Bearer</strong> (Token Authentication) rápidamente en nuestra API con Rails 8 más los archivos ya generados.</p>
<p>El primer paso será agregar <strong>persistencia para nuestro token</strong>, para esto modificaremos la migración que crea las sessiones y agregaremos un nuevo campo llamado <code class="language-plaintext highlighter-rouge">token</code>:</p>
<div class="language-ruby highlighter-rouge"><div class="highlight"><pre class="highlight"><code> <span class="n">create_table</span> <span class="ss">:sessions</span> <span class="k">do</span> <span class="o">|</span><span class="n">t</span><span class="o">|</span>
<span class="n">t</span><span class="p">.</span><span class="nf">references</span> <span class="ss">:user</span><span class="p">,</span> <span class="ss">null: </span><span class="kp">false</span><span class="p">,</span> <span class="ss">foreign_key: </span><span class="kp">true</span>
<span class="n">t</span><span class="p">.</span><span class="nf">string</span> <span class="ss">:ip_address</span>
<span class="n">t</span><span class="p">.</span><span class="nf">string</span> <span class="ss">:user_agent</span>
<span class="n">t</span><span class="p">.</span><span class="nf">string</span> <span class="ss">:token</span> <span class="c1"># HERE</span>
<span class="n">t</span><span class="p">.</span><span class="nf">timestamps</span>
<span class="k">end</span>
</code></pre></div></div>
<p>Ahora simplemente ejecuta <code class="language-plaintext highlighter-rouge">rails db:migrate</code> y create un usuario de prueba por consola, yo lo haré con esta línea <code class="language-plaintext highlighter-rouge">User.create(email_address: "<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="a6d3d5c3d4e6d2c3d5d288c5c9cb">[email&#160;protected]</a>", password: "123456789")</code> (Lo utilizaremos más tarde). Luego debemos crear un nuevo token para cada sesión nueva de un usuario, para esto lo más simple es usar un callback en el modelo <code class="language-plaintext highlighter-rouge">Session</code>:</p>
<div class="language-ruby highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="c1"># app/models/sessions.rb</span>
<span class="k">class</span> <span class="nc">Session</span> <span class="o">&lt;</span> <span class="no">ApplicationRecord</span>
<span class="n">belongs_to</span> <span class="ss">:user</span>
<span class="n">before_create</span> <span class="ss">:generate_token</span> <span class="c1"># Here call</span>
<span class="kp">private</span>
<span class="k">def</span> <span class="nf">generate_token</span> <span class="c1"># Here implement, generate the token as you wish.</span>
<span class="nb">self</span><span class="p">.</span><span class="nf">token</span> <span class="o">=</span> <span class="no">Digest</span><span class="o">::</span><span class="no">SHA1</span><span class="p">.</span><span class="nf">hexdigest</span><span class="p">([</span> <span class="no">Time</span><span class="p">.</span><span class="nf">now</span><span class="p">,</span> <span class="nb">rand</span> <span class="p">].</span><span class="nf">join</span><span class="p">)</span>
<span class="k">end</span>
<span class="k">end</span>
</code></pre></div></div>
<p>Ahora volviendo al metodo <code class="language-plaintext highlighter-rouge">start_new_session_for</code> en el concern <code class="language-plaintext highlighter-rouge">Authentication</code>, no es necesario que creemos una cookie, asi que debemos remover esa linea y dejar el metodo de la siguiente forma:</p>
<div class="language-ruby highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="c1"># app/controllers/concerns/authentication.rb</span>
<span class="k">def</span> <span class="nf">start_new_session_for</span><span class="p">(</span><span class="n">user</span><span class="p">)</span>
<span class="n">user</span><span class="p">.</span><span class="nf">sessions</span><span class="p">.</span><span class="nf">create!</span><span class="p">(</span><span class="ss">user_agent: </span><span class="n">request</span><span class="p">.</span><span class="nf">user_agent</span><span class="p">,</span> <span class="ss">ip_address: </span><span class="n">request</span><span class="p">.</span><span class="nf">remote_ip</span><span class="p">).</span><span class="nf">tap</span> <span class="k">do</span> <span class="o">|</span><span class="n">session</span><span class="o">|</span>
<span class="no">Current</span><span class="p">.</span><span class="nf">session</span> <span class="o">=</span> <span class="n">session</span>
<span class="k">end</span>
<span class="k">end</span>
</code></pre></div></div>
<p>Y modificaremos el <code class="language-plaintext highlighter-rouge">create</code> de <code class="language-plaintext highlighter-rouge">SessionsController</code> para que las respuestas sean en formato json y no redirecciones:</p>
<div class="language-ruby highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="c1"># app/controllers/sessions_controller.rb</span>
<span class="k">def</span> <span class="nf">create</span>
<span class="k">if</span> <span class="n">user</span> <span class="o">=</span> <span class="no">User</span><span class="p">.</span><span class="nf">authenticate_by</span><span class="p">(</span><span class="n">params</span><span class="p">.</span><span class="nf">permit</span><span class="p">(</span><span class="ss">:email_address</span><span class="p">,</span> <span class="ss">:password</span><span class="p">))</span>
<span class="n">start_new_session_for</span> <span class="n">user</span>
<span class="n">render</span> <span class="ss">json: </span><span class="p">{</span> <span class="ss">data: </span><span class="p">{</span> <span class="ss">token: </span><span class="no">Current</span><span class="p">.</span><span class="nf">session</span><span class="p">.</span><span class="nf">token</span> <span class="p">}</span> <span class="p">}</span>
<span class="k">else</span>
<span class="n">render</span> <span class="ss">json: </span><span class="p">{},</span> <span class="ss">status: :unauthorized</span>
<span class="k">end</span>
<span class="k">end</span>
</code></pre></div></div>
<p><strong>Para hacer que todo esto funcione debemos hacer dos cosas:</strong></p>
<ol>
<li>
<p>Incluir el modulo <code class="language-plaintext highlighter-rouge">Authentication</code> en <code class="language-plaintext highlighter-rouge">ApplicationController</code>:</p>
<div class="language-ruby highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="c1"># app/controllers/application_controller.rb</span>
<span class="k">class</span> <span class="nc">ApplicationController</span> <span class="o">&lt;</span> <span class="no">ActionController</span><span class="o">::</span><span class="no">API</span>
<span class="kp">include</span> <span class="no">Authentication</span>
<span class="k">end</span>
</code></pre></div> </div>
</li>
<li>
<p>Eliminar la linea numero 6 de este mismo concern:</p>
<div class="language-ruby highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="c1"># app/controllers/concerns/authentication.rb</span>
<span class="n">included</span> <span class="k">do</span>
<span class="n">before_action</span> <span class="ss">:require_authentication</span>
<span class="n">helper_method</span> <span class="ss">:authenticated?</span> <span class="c1"># This, we don't use helpers in APIs</span>
<span class="k">end</span>
</code></pre></div> </div>
</li>
</ol>
<p>Hasta este punto ya deberíamos tener el <strong>login funcionando</strong>. Para probar esto voy a agregar <a href="https://github.com/a-chacon/oas_rails">OasRails</a>, que a propósito <strong>ya está funcionando con Rails 8</strong> y voy a enviar un par de peticiones a ver como se comporta, no explicaré como implementar OasRails, para eso puedes ver el repositorio o leer más en <a href="/on rails/2024/07/25/documenting-rails-apis">este post</a>.</p>
<p>Inicio de sesión exitoso:</p>
<p><img src="/assets/images/rails8_success_login.png" alt="" /></p>
<p>Inicio de sesión fallido:</p>
<p><img src="/assets/images/rails8_fail_login.png" alt="" /></p>
<hr />
<p>Ya podemos generar tokens, ahora modificaremos el código para <strong>autenticarnos con ese mismo token</strong>. Para eso, cambiaremos la lógica de buscar la sesión actual del usuario con base en la cookie a buscarla basándonos en la cabecera <code class="language-plaintext highlighter-rouge">Authorization</code>:</p>
<div class="language-ruby highlighter-rouge"><div class="highlight"><pre class="highlight"><code>
<span class="c1"># app/controllers/concerns/authentication.rb</span>
<span class="k">def</span> <span class="nf">resume_session</span>
<span class="no">Current</span><span class="p">.</span><span class="nf">session</span> <span class="o">=</span> <span class="n">find_session_by_token</span>
<span class="k">end</span>
<span class="k">def</span> <span class="nf">find_session_by_cookie</span>
<span class="no">Session</span><span class="p">.</span><span class="nf">find_by</span><span class="p">(</span><span class="ss">token: </span><span class="n">request</span><span class="p">.</span><span class="nf">headers</span><span class="p">[</span><span class="ss">:authorization</span><span class="p">]</span><span class="o">&amp;</span><span class="p">.</span><span class="nf">split</span><span class="p">(</span><span class="s2">" "</span><span class="p">)[</span><span class="o">-</span><span class="mi">1</span><span class="p">])</span>
<span class="k">end</span>
</code></pre></div></div>
<p>Para probar esto creo que tendremos que hacer rápidamente un modelo que dependa de <code class="language-plaintext highlighter-rouge">User</code> y que requiera autenticación para utilizar. Intentemos con <code class="language-plaintext highlighter-rouge">rails g scaffold project title:string description:text user:references</code> y le agregamos al principio del controlador la línea de código <code class="language-plaintext highlighter-rouge">before_action :require_authentication</code>.</p>
<p>Aquí les dejo una pequeña prueba del index de Projects autenticado con el token que obtuve en las pruebas anteriores:</p>
<p><img src="/assets/images/rails8_projects.png" alt="" /></p>
<hr />
<p>Con esto ya tienes gran parte de la lógica de autenticación funcionando en la aplicación API-Only. Te queda continuar con las modificaciones en el resto de los endpoints para que las respuestas sean en formato json y no supuestas vistas que no existen en la aplicación.</p>
<p>Probablemente de aquí a que se lance la versión final de Rails 8 aparezca un <strong>PR solucionando esto y el generador funcione correctamente en modo API-Only</strong>. Hasta entonces, con estas pequeñas modificaciones ya puedes seguir construyendo tu API.</p>
