获取订购菜肴(Django ORM)中所有使用的配料的数量，以创建购物清单

from django.db import models

class Ingredient(models.Model):
    name = models.CharField(max_length=100)
    # 其他配料属性...

class Dish(models.Model):
    name = models.CharField(max_length=100)
    ingredients = models.ManyToManyField(Ingredient)
    # 其他菜肴属性...

from django.db.models import Count

def get_shopping_list(request):
    # 获取所有菜肴使用的配料，并按照配料的数量进行分组统计
    ingredient_counts = Ingredient.objects.annotate(count=Count('dish')).order_by('-count')

    # 创建购物清单
    shopping_list = []
    for ingredient in ingredient_counts:
        shopping_list.append({
            'ingredient': ingredient,
            'quantity': ingredient.count
        })

    # 返回购物清单数据
    return shopping_list
