How Do I Make An "order" Products App Like This

My name is Federico I need to make a system for my company, we sell perfumes, in a first stage I only need an app where people can choose between 5 perfumes types, when they chose

Solution 1:

Looks like you've almost got it :)

The approach I would use would be:

classAroma(models.Model):
    nombre = models.CharField(max_length=30)

classLineaProducto(models.Model):
    nombre = models.CharField(max_length=40)

classTipoProducto(models.Model):
    nombre = models.CharField(max_length=20)
    linea_producto = models.ForeignKey(LineaProducto, on_delete=models.CASCADE)

classProducto(models.Model):
    nombre = models.CharField(max_length=20)
    aromas = models.ManyToManyField(Aroma)
    tipo_producto = models.ForeignKey(TipoProducto, on_delete=models.CASCADE)
    precio_mayorista = models.IntegerField(default=0)
    precio_final = models.IntegerField(default=0)

The LineaProducto would be the "Type", The TipoProducto would be the "Family" and the Producto would be the product.

Hopefully this sets you in the right direction!
