How can I get top 5 inventory items from a django model which has lowest quantity?

Question

#This is my inventory model. I want to get the inventory items that have the lowest quantity in the model.

class Inventory(models.Model):
    name = models.CharField(max_length=100)
    purchase_date = models.DateTimeField()
    category = models.ForeignKey(Category, on_delete=models.CASCADE)
    
    quantity = models.CharField(max_length=50)
    purchase_price = models.FloatField(max_length=50)
    selling_price = models.FloatField(max_length=50)
    description = models.CharField(max_length=100)
    location = models.ForeignKey(Locations, on_delete=models.CASCADE)
    created_date = models.DateField(auto_now_add=True)

Answer 1

To get a number of results with the lowest or highest value you first order by that field order_by('quantity') so that the results you want will be first, then you can slice the queryset to limit the number of results

The quantity field should really be a PositiveIntegerField or IntegerField since it stores integers

top_five_least_quantity = Inventory.objects.order_by('quantity')[:5]
