python - 使用srid 4326的GeoDjango距离查询返回＆＃39; SpatiaLite不支持使用大地坐标系的几何场上的距离查询。＆＃39;

我试图在距离给定纬度/长度4公里半径范围内的附近厨房。我的空间后端是空间和设置，


    INSTALLED_APPS = (
        'django.contrib.admin',
        'django.contrib.auth',
        'django.contrib.contenttypes',
        'django.contrib.sessions',
        'django.contrib.messages',
        'django.contrib.staticfiles',
        'django.contrib.gis',
        'rest_framework',
        'oauth2_provider',
        'kitchen',
    )

    DATABASES = {
        'default': {
            'ENGINE': 'django.contrib.gis.db.backends.spatialite',
            'NAME': os.path.join(BASE_DIR, 'db.sqlite3'),
        }
    }

这是我的模特


    from django.contrib.gis.db import models
    from django.contrib.gis.geos import Point

    class Kitchen(models.Model):
        id = models.CharField(max_length=100,primary_key=True)
        #id = models.AutoField(primary_key=True)
        name = models.CharField(max_length=100,blank=False)
        address = models.CharField(max_length=1000, blank=True, default='')
        contact_no = models.CharField(max_length=100,blank=True, default='')
        location = models.PointField(srid=4326, geography=True, blank=True, null=True)
        objects = models.GeoManager()

来自Django shell的查询是，


    from kitchen.models import Kitchen
    from django.contrib.gis import measure
    from django.contrib.gis import geos

    current_point = geos.fromstr('POINT(%s %s)' % (76.7698996, 17.338993), srid=4326)
    Kitchen.objects.filter(location__distanc

e_lte=(current_point, measure.D(km=4)))

返回以下值错误，


    SpatiaLite does not support distance queries on geometry fields with a geodetic coordinate system. Distance objects; use a numeric value of your distance in degrees instead.

在模型中设置不同的投影srid（例如3857,24381等）会返回不正确的结果。这里的一些帮助将不胜感激。
