无法将关键字“distance_gte”解析为字段。 选项有：Shop_category、address、distance、id、name、shop_location、user、user_id

Question

我有两个model店和客户

店铺

class Shop(models.Model):
     address = models.CharField(max_length=70, null=True)
    Shop_category = models.CharField(max_length=200, null=True, ) 
    Name=models.CharField(max_length=70)
     distance = models.PositiveIntegerField(null=True)
     shop_location = models.PointField(null=True, default=Point(28.49, 77.33))

顾客

class Customer(models.Model):
        user = models.OneToOneField(User, null=True, 
           on_delete=models.CASCADE)
    customer_location = models.PointField(null=True, default=Point(28.49, 77.33))

我想在商店里设置过滤器。 店铺与顾客的距离是否低于 shop.distance 和 my views.py 给出的距离，店铺会显示给顾客

from django.contrib.gis.db.models.functions import Distance
  Shop_list = Shop.objects.filter(
    distance_gte=Distance('shop_location',    
    request.user.customer.customer_location)
)

我收到错误无法将关键字“distance_gte”解析到字段中。 选择是：Shop_category、address、distance、id、name、shop_location、user、user_id

Answer 1

您需要使用双下划线进行查找，因此：

from django.contrib.gis.db.models.functions import Distance

Shop_list = Shop.objects.filter(
    distance__gte=Distance(
        'shop_location',    
        request.user.customer.customer_location
    )
)
