Mi opinión: ¿Qué pinta deberían de tener los Service objects en Rails?
¡Muy buenas a todos! Cuánto tiempo, ¿no?. Quizás te preguntes, ¿qué te ha pasado Alberto? La verdad es que llevo años (y lo digo en serio) queriendo acompañar mis posts con videos en YouTube y me prometí que el siguiente post llevaría un vídeo sí o sí… ¡lo que no anticipaba es que me costaría […]
My thoughts: How should service objects in Rails ideally look like?
Hi everybody! What a hiatus, right? If you are asking yourself, what happened to you Alberto? The reality is that for a long time I wanted to included YouTube videos in my post and I promised myself that the next post I published would have a video for sure… what I did not anticipate is […]

Phoenix: The request assembly line

Print Ruby objects internal state: puts vs p
Today I decided to make a short post about how to print an object’s internal state. puts Usually when we want to print out something in Ruby, the first method that comes to our mind is puts. The method puts prints all the arguments we pass in to it and inserts a new line after each […]
