 Dear developers,

 Django 1.8 introduced the `TestCase.setUpTestData()` class method as a
 mean to
 speed up test fixtures initialization as compared to using `setUp()`[0].

 As I've come to use this feature and review changes from peers using it
 in
 different projects the fact that test data assigned during its execution
 couldn't be safely altered by test methods without compromising test
 isolation
 has often be the source of confusion and frustration.

 While the `setUpTestData` documentation mentions this limitation[1] and
 ways to
 work around it by using `refresh_from_db()` in `setUp()` I believe it
 defeats

select quantity for each items selected in many to many field

[hunar techie]

hi there i'm working on an restaurant ordering system , when someone order
more than one product with different quantities for each product , be able
to select its quantities
it may order 3 Pizza with 2 sandwich , how to let the customer to define
the quantities of each product , and then calculate with its prices
 class Restaurant(models.Model):

name = models.CharField(max_length=50)
price = models.PositiveIntegerField(default=1)


def __str__(self):
return self.name
class Topping(models.Model):
name = models.CharField(max_length=50)
product_names = models.ManyToManyField(Restaurant, blank=True)
quantity = models.PositiveIntegerField(default=1)


total price of orders , for one product for example : one pizza with
one sandwich however they order more than one pizza and sandwich

@property
def total(self):
return self.product_names.aggregate(Sum('price'))['price__sum']

I expected to provide a quantity field for each selected items : pizza : 3
, sandwich:2 , then calculate them (3*pizza price , 2*sandwich price)

thanks for advice
