在我的Django應用程序，一個登錄的用戶可以創建一個Entry它具有以下屬性在Django使用高速緩存 - 如何創建密鑰
from django.db import models
from datetime import date
from django.contrib.auth.models import User
class Entry(models.Model):
creationdate=models.DateField(default=date.today)
description=models.TextField()
author=models.ForeignKey(User,null=True)
在我看來，用戶可以檢索所有Entry S代表特定日期
def entries_on_ a_day(request,year,month,day):
#month as 'jan','feb' etc
...
entries_for_date = Entry.objects.filter(creationdate__year=year,creationdate__month=get_month_as_number(month),creationdate__day=day,author=request.user).order_by('-creationdate')
...
現在，我需要使用cache這一點，而不是做一個數據庫的命中每次用戶希望看到我應該設置緩存鍵day.How的Entry個上市？我是否應該使用由username+creationdate組成的字符串作爲關鍵字？
from django.core.cache import cache
def entries_on_ a_day(request,year,month,day):
creationdate=new date(year,get_month_as_number(month),day)
key = request.user.username+ str(creationdate)
if key not in cache:
entries_for_date = Entry.objects.filter(creationdate__year=year,creationdate__month=get_month_as_number(month),creationdate__day=day,author=request.user).order_by('-creationdate')
cache.set(key,entries_for_date)
entries = cache.get(key)
....
