django - 时区 它在本地工作，但在 pythonanywhere (DJango) 中不起作用

Question

我有一个查询集来列出今天的销售额

from django.utils import timezone

class VentaToday(ListView):
    queryset = Venta.objects.filter(fecha=timezone.now()).order_by('-id')
    template_name = 'venta/venta_today.html'

在本地，这可以正常工作，但在生产环境 (Pythonanywhere) 中，前一天的销售额不断出现。要修复它，我必须转到 pythonanywhere 面板并单击 ** reload ** 按钮来解决问题。

我更改了服务器时间:

django项目的配置:

LANGUAGE_CODE = 'es-pe'

TIME_ZONE = 'America/Lima'

USE_I18N = True

USE_L10N = True

USE_TZ = True

是不是服务器缓存问题？或者我做错了什么？

更新 配置 WSGI:

# +++++++++++ DJANGO +++++++++++
# To use your own django app use code like this:
import os
import sys

os.environ["TZ"] = "America/Lima"
#
## assuming your django settings file is at '/home/dnicosventas/mysite/mysite/settings.py'
## and your manage.py is is at '/home/dnicosventas/mysite/manage.py'
path = '/home/dnicosventas/dnicos-ventas'
if path not in sys.path:
    sys.path.append(path)
#
os.environ['DJANGO_SETTINGS_MODULE'] = 'DnicosVentas.settings'
#
## then, for django >=1.5:
from django.core.wsgi import get_wsgi_application
application = get_wsgi_application()
## or, for older django <=1.4
import django.core.handlers.wsgi
application = django.core.handlers.wsgi.WSGIHandler()

和我的控制台:

export TZ="/usr/share/zoneinfo/America/Lima"

即便如此，在中午 12 点之后，昨天的销售情况一直出现，直到我单击 pythonanywhere 面板中的重新加载按钮。

Views.py:

class VentaToday(ListView):
    today = datetime.now(pytz.timezone('America/Lima'))
    queryset = Venta.objects.filter(fecha=today).order_by('-id')
    template_name = 'venta/venta_today.html'

Giles Thomas 的解决方案:

class VentaToday(ListView):
template_name = 'venta/venta_today.html'
    def get_queryset(self):
        return Venta.objects.filter(fecha=datetime.now(pytz.timezone('America/Lima'))).order_by('-id')
