在Django中从direct_to_template移到新的TemplateView

传递extra_context的唯一方法是子类TemplateView并提供自己的get_context_data方法。这是我想出的

DirectTemplateView

extra_context

direct_to_template

from django.views.generic import TemplateViewclass DirectTemplateView(TemplateView):    extra_context = None    def get_context_data(self, **kwargs):        context = super(self.__class__, self).get_context_data(**kwargs)        if self.extra_context is not None: for key, value in self.extra_context.items():     if callable(value):         context[key] = value()     else:         context[key] = value        return context

使用此类，你将替换：

(r'^$', direct_to_template, { 'template': 'index.html', 'extra_context': {     'form': CodeAddForm,     'topStores': get_topStores,     'newsStories': get_dealStories,     'latestCodes': get_latestCode,     'tags':get_topTags,     'bios':get_bios}},  'index'),

与：

(r'^$', DirectTemplateView.as_view(template_name='index.html', extra_context={     'form': CodeAddForm,     'topStores': get_topStores,     'newsStories': get_dealStories,     'latestCodes': get_latestCode,     'tags':get_topTags,     'bios':get_bios}), 'index'),
