问题描述

如何在Django的Createview中声明一个变量，所以我可以从它的模板中使用它？
例如我想在模板中使用{{place_slug}}。我从urls.py传递如下：

How do I declare a variable in Django's Createview, so I can use it from its template? For example I want to use {{ place_slug }} in the template. I pass that from urls.py like below:

urls.py：

urlpatterns = patterns('',
    (r'^new/(?P<place_slug>[\w\-\_]+)/?$', PictureCreateView.as_view(), {}, 'upload-new'),
)

views.py： p>

views.py:

class PictureCreateView(CreateView):
    model = Picture

    def dispatch(self, *args, **kwargs):
        self.place = get_object_or_404(Place, slug=kwargs['place_slug'])
        return super(PictureCreateView, self).dispatch(*args, **kwargs)

    def form_valid(self, form):

推荐答案

覆盖get_context_data并设置context_data ['place_slug'] = your_slug

Override get_context_data and set context_data['place_slug'] = your_slug

如下所示：

def get_context_data(self, **kwargs):
    context = super(PictureCreateView, self).get_context_data(**kwargs)
    context['place_slug'] = self.place.slug
    return context
