让 Django 管理员在发布后记住我的参数

我有一个问题困扰了我一段时间。我想使用 django admin 中的日期来查看特定日期之间的条目。为此，我为此模型定制了changelist.html，并在其中放置了一个表单。当发布时，我重写了这样的查询集方法，

def queryset(self, request):
    qs = super(ModelAdmin, self).queryset(request)

    if request.POST.has_key('date1'):
        return qs.filter(startdate__gte=request.POST['date1']).filter(startdate__lte=request.POST['date2'])               
    return qs

这很好用，但只有一个小问题。例如，如果我选择以任何方式对结果进行排序，则参数会被忘记。

如果我不直接在浏览器中输入网址，那么它看起来像这样

http//localhost/admin/some/model/?startdate__gte=2010-01-01&startdate__lte=2010-12-30

我可以排序之后想要因为他们会像这样粘在一起 http//localhost/admin/some/model/?o=5&ot=asc&startdate__lte=2010-12-30&startdate__gte=2010-01-01

我需要使用filterspec来解决这个问题吗？

多谢多谢！

I have a problems thats been bugging me for a while. I want to use dates in django admin to view entries between certain dates.
To do this I have customized my changelist.html for this model and put a form in there. When posted I override the queryset method like this

def queryset(self, request):
    qs = super(ModelAdmin, self).queryset(request)

    if request.POST.has_key('date1'):
        return qs.filter(startdate__gte=request.POST['date1']).filter(startdate__lte=request.POST['date2'])               
    return qs

This works great but its only one little problem. The parameters are forgotten if I for example choose to sort the result in any way.

If I instead of this type in the url straight into the browser so it looks like this

http//localhost/admin/some/model/?startdate__gte=2010-01-01&startdate__lte=2010-12-30

I can sort however I want to afterwards because they´ll stick just like this
http//localhost/admin/some/model/?o=5&ot=asc&startdate__lte=2010-12-30&startdate__gte=2010-01-01

Do I need to use a filterspec to solve this?

Thanks heaps!
