如何将表单传递给 get_context_data function？

Question

如何在这里获取表单变量？

def get_context_data(self, **kwargs):

    context = super().get_context_data(**kwargs)
    context['form'] = kwargs['form']
    return context

注释 model 代码：

class Comment(models.Model):
author = models.ForeignKey(User, on_delete=models.CASCADE)
post = models.ForeignKey(Post, on_delete=models.CASCADE)

text = models.TextField()
date_posted = models.DateTimeField(auto_now_add=True)

def __str__(self):
    return str(self.id)

查看 class：

class CommentCreate(LoginRequiredMixin, CreateView):
model = Comment
fields = ('text', )
template_name = 'post/details.html'

def form_valid(self, form):
    form.instance.author = self.request.user
    return super().form_valid(form)

def get_context_data(self, **kwargs):

    context = super().get_context_data(**kwargs)
    context['form'] = kwargs['form']
    return context

详细视图：

class PostDetailView(DetailView):
model = Post
context_object_name = 'post'
template_name = 'post/details.html'

def get_context_data(self, **kwargs):
    context = super().get_context_data(**kwargs)
    return context
