Test

Let's start 

Mongoose !

Let's start with mongoose !

Example : 

  1. // Include virtuals when converting documents to objects/JSON
  2. pizzaSchema.set("toObject", { virtuals: true });
  3. pizzaSchema.set("toJSON", { virtuals: true });

  4. // Virtual populate: connect Pizza -> Topping via Topping.pizzas (inverse relation)
  5. pizzaSchema.virtual("toppings", {
  6.   ref: "Topping",
  7.   localField: "_id",
  8.   foreignField: "pizzas",
  9.   justOne: false,
  10. });

  11. // Virtual total price (cents) includes toppings when `toppings` is populated
  12. pizzaSchema.virtual("totalPriceCents").get(function () {
  13.   // Compute total price from populated `toppings` only (no base pizza price)
  14.   if (
  15.     !this.toppings ||
  16.     !Array.isArray(this.toppings) ||
  17.     this.toppings.length === 0
  18.   )
  19.     return 0;
  20.   return this.toppings.reduce((acc, t) => acc + (t.priceCents || 0), 0);
  21. });

  22. pizzaSchema.virtual("totalPriceEur").get(function () {
  23.   return (this.totalPriceCents || 0) / 100;
  24. });

  25. export const Pizza = mongoose.model("Pizza", pizzaSchema);

🚩 PUT/DELETE how-to

 💡 Les navigateurs ne supportent que GET et POST en natif dans les formulaires. Découvrez comment gérer DELETE et PUT. 

Méthode CRUD

Support natif HTML

Solution avec Express

Create (POST)

✅ Oui

<form method="POST">

Read (GET)

✅ Oui

<form method="GET">

Update (PUT)

❌ Non

method-override + POST

Delete (DELETE)

❌ Non

method-override + POST




Delete/update

  • In this repository we keep things explicit and simple by using POST endpoints for update and delete actions (for example /posts/:id/update and /posts/:id/delete). Those endpoints accept normal POST form submissions and return normal redirects or rendered pages.

  • HTML forms only submit GET or POST. method-override is a middleware used to turn a POST into a PUT/DELETE on the server (usually by reading a hidden _method field or a query parameter).

  • This project was converted to an API-first, client-rendered demo where the server returns JSON and the frontend (in public/index.html and public/js/app.js) uses fetch() to perform CRUD operations.
