Question

我需要创建基于月份的视图。我可以按月过滤我的输入项目，我可以在html页面上显示它们。我正在努力做的只是显示您从主页面选择的月份数据。例如，如果您点击11月，它会转到仅显示11月项目的页面，依此类推。我需要一个特定的url配置吗？我希望有一种更简单的方法来做到这一点，而不是每个月创建一个视图，然后创建每个月的网址...

urls.py

urlpatterns = [
    url(r'^$', views.IndexView.as_view(), name='index'),

    url(r'entry/list/?P<month_here>$', views.EntryListView.as_view(), name='entry-list'),

]

views.py

class EntryListView(generic.ListView):
    template_name = 'argent/index_list.html'
    context_object_name = 'object_list'

    def get_queryset(self):
        return Entry.objects.all()

    def get_context_data(self, **kwargs):
        mth = super(EntryListView, self).get_context_data(**kwargs)

        # ENTRY BY MONTH

        # January17
        mth['January17_qs'] = Entry.objects.filter(date__range=('2017-1-1', '2017-1-31'))

        # February17
        mth['February17_qs'] = Entry.objects.filter(date__range=('2017-2-1', '2017-2-28'))

        return ctx

您可以从url解析args。以上内容将在您的视图中添加一个名称＆＃34; month＆＃34;的查询参数，该单词应该是一个单词（\ w + regex）

month = self.kwargs.get('month')

然后在get_context_data中你应该在你的kwargs中有这个：

def get_context_data(self, **kwargs):
    mth = super(EntryListView, self).get_context_data(**kwargs)

    # ENTRY BY MONTH
    month = self.kwargs.get('month')

    # January17
    if month == 'january:
      mth['January17_qs'] = Entry.objects.filter(date__range=('2017-1-1', '2017-1-31'))
    elif month == 'february':
      # February17
      mth['February17_qs'] = Entry.objects.filter(date__range=('2017-2-1', '2017-2-28'))

    return mth

然后添加逻辑，解析你的args然后返回正确的查询集。

for year in range(2016, 2019):
    mth["{}{}_qs".format(month.title(), str(year)[-2:])] = Entry.objects.filter(date__range=("{}-1-1".format(year), "{}-1-31".format(year))
# this will add you a 'January16_qs', 'January17_qs', 'January18_qs' variables if month is 'january'

多年来你还可以添加一些for-clausule来构建你的参数：

Django url按数据组配置
