Ok. This is quite strange or I am missing something fundamentally important in the looping objects business. I have three objects, let's say they are fruits, basket, and fruit basket. I also would like to record the action of putting or taking fruit from the basket. for models:
class BasketFruit(models.Model):
"""
A fruit within a basket.
"""
basket = models.ForeignKey(Basket, related_name='fruit_basket')
fruit = models.ForeignKey(Fruit)
number_owned = models.IntegerField()
class Meta:
unique_together = (("basket", "fruit"),)
class Fruit(models.Model):
name = models.CharField(max_length = 250)
class Basket(models.Model):
name = mdoels.CharField(max_length =250)
class Operation(models.Model):
expired = models.BooleanField()
The goal is to loop through all baskets and take out the a basket fruit and check if it is expired. I have a function to check def expired() which I know it is good. Now I want to record expired into class Operation while looping through each basket. In my views I have this:
def record_expiration():
baskets = list(Basket.objects.all())
for basket in baskets:
fruits_in_basket = basket.fruist_basket.all()
for fruits in fruits_in_basket:
numbers = fruits.number_owned
if numbers != 0:
names.append(fruit.fruit.name)
expired = map(lampda name:expired(name), names)
for expired in expired:
if expired ==True:
Operation.objects.create(fruitbasket = fruits, expired
= expired)
return fruits
Strangely only one basket and one basket fruit in it is returned when I run the code regardless how many baskets or basket fruit objects I have? TO Python expert, any idea why? `
