Django：如何在基于类的视图中获取昨天的查询集？

http://ccbv.co.uk/projects/Django/1.4/django.views.generic.dates/TodayArchiveView/

我使用 TodayArchiveView。

顺便说一句，如果 TodayArchiveView 得到 None，TodayArchiveView.as_view() 会引发 Http404。

在这种情况下，我想在当前模型（表）中推送昨天的数据......

我应该怎么办？

一些代码在这里：

网址.py

from django.conf.urls import patterns, include, url
from crm.views import *

urlpatterns = patterns('',
    (r'^workDailyRecord/$', workDailyRecord),
)

视图.py

from django.views.generic import TodayArchiveView
from django.http import Http404
from crm.models import *

def workDailyRecord(request):
    if request.method === 'GET':
        tView.as_view() # I want call class-based generic views at this line.
    elif:
        try:
            return tView.as_view()(request)
        except Http404:
            # I want to push data at yesterday in 'WorkDailyRecord' model
            pass

class tView(TodayArchiveView):
    model = WorkDailyRecord
    context_object_name = 'workDailyRecord'
    date_field = 'date'
    template_name = "workDailyRecord.html"

模型.py

from django.db import models

class WorkDailyRecord(models.Model):
    date = models.DateTimeField(auto_now_add=True)
    contents = models.TextField()
