在我的页面上,我需要显示帖子详细信息和评论表单以供查看者发表评论。我创建了 2 个通用视图:
# views.py
class PostDetailView (DetailView):
model = Post
context_object_name = 'post'
template_name = 'post.html'
def get_context_data(self, **kwargs):
context = super(PostDetailView, self).get_context_data(**kwargs)
context['comment_form'] = CommentForm()
return context
class AddCommentView(FormView):
template_name = 'post.html'
form_class = CommentForm
success_url = '/'
def form_valid(self, form):
form.save()
return super(AddCommentView, self).form_valid(form)
def form_invalid(self, form):
return self.render_to_response(self.get_context_data(form=form))
detail = PostDetailView.as_view()
add_comment = AddCommentView.as_view()
# urls.py
....
url(r'^(?P<pk>\d+)/$', view='detail'),
url(r'^(?P<post_id>\d+)/add_comment/$', view='add_comment'),
....
AddCommentView 中会出现错误,因为我没有为评论指定帖子的 ID。如何访问 AddCommentView 中的 post_id?
