无法将关键字'distance_gte'解析为字段。选项包括：Shop_category，地址，距离，id，名称，shop_location，用户，user_id

Question

我有两个样板店和客户

商店

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))

客户

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))

我想在商店设置过滤器。如果商店与顾客之间的距离小于商店给出的距离，商店将向顾客显示。和我的views.py

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

我遇到错误，无法将关键字'distance_gte'解析为字段。选择是：商店类别，地址，距离，ID，名称，商店位置，用户，用户ID

Answer 1

您需要使用双下划线进行查找，所以：

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

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