django-views

问题 I would like to dynamically change the form_class of an UpdateView CBV in Django 1.6. I've tried to do this using the get_context_data(), but that didn't help since the form is already initialized. So it will need to happen during __init__ , I guess. Here's what I've tried on __init__ : class UpdatePersonView(generic.UpdateView): model = Person form_class = "" def __init__(self, *args, **kwargs): super(UpdatePersonView, self).__init__(*args, **kwargs) person = Person.objects.get(id=self.get

问题 How do I add extra context to all admin webpages? I use default Django Admin for my admin part of a site. Here is an url entry for admin: urlpatterns = [ url(r'^admin/', admin.site.urls), ] And my apps register their standard view models using: admin.site.register(Tag, TagAdmin) My problem, is that I want to display an extra field in admin template header bar and I have no idea how to add this extra context. My first bet was adding it in url patterns like below: urlpatterns = [ url(r'^admin/'

问题 I'm trying to scrape a web page using BeautifulSoup and Django.
