Django的。干。获取请求中的相同上下文

Question

我正在尝试使用Django开发投票应用程序。 在此处显示投票的视图。

class DetailVoteView(View):
    """
    Displays the vote
    If vote is active allows to vote
    If vote is completed shows winners and top 5
    """
    vote = None
    vote_for_chars = None
    page_title = ''

    def dispatch(self, request, *args, **kwargs):
        self.vote = Vote.objects.get(id=kwargs['id'])
        self.vote_for_chars = self.vote.voteforcharacter_set.all()
        self.page_title = self.vote.title
        return super(DetailVoteView, self).dispatch(request, *args, **kwargs)

    def get(self, request, id):

        if is_active_vote(self.vote):
            nominates = self.vote_for_chars
            return render(request, 'vote_detail/active_vote_detail.html', context={
                'page_title': self.page_title,

                'vote': self.vote,
                'votes_name': self.page_title,

                'nominates': nominates,
            })
        else:
            winners = []
            top_fives = []
            if self.vote.voteforcharacter_set.count() != 0:
                sorted = self.vote.voteforcharacter_set.order_by('-votes_number')
                winner_number_votes = sorted[0].votes_number
                winners = self.vote_for_chars.filter(votes_number__exact=winner_number_votes)
                top_fives = sorted[winners.count():5 + winners.count()]
            return render(request, 'vote_detail/completed_vote_detail.html', context={
                    'page_title': self.page_title,

                    'vote': self.vote,
                    'votes_name': self.page_title,

                    'winners': winners,
                    'top_fives': top_fives
                })

    def post(self, request, id):
        vote_for_chars = self.vote_for_chars
        id_to_vote = request.POST.get("id_to_vote")
        char_to_vote = vote_for_chars.get(character__id=id_to_vote)
        char_to_vote.votes_number += 1
        char_to_vote.save()
        return HttpResponseRedirect('/')

代码不是我想的那样干。因为，在reuqest中存在相同的上下文。 我需要使用mixins功能吗？ 我该如何改善？谢谢。

已编辑。

添加了模板代码。

acvtive_vite_detail.html

{% extends 'base/base.html' %}
