django - 基于Django类的视图和注释(Django class based view and comments)

Question

I'm having trouble with adding comments to class based views, forms.py:

(我在向基于类的视图forms.py添加注释时遇到麻烦：)

  class RequestForm(ModelForm):
      class Meta:
          model = Request
          exclude = ('slug',)
  class RequestCommentForm(ModelForm):
      class Meta:
          model = RequestComment
          fields = ['body' ]

models.py:

(models.py：)

class Request(models.Model):
    title = models.CharField(max_length=250 )
    date = models.DateTimeField('Request date', default=timezone.now, editable=False )
    department = models.CharField(max_length=2, choices=DEPARTMENT)
    support_request = models.TextField('Request', max_length=2500, blank=True)
    owner = models.ForeignKey(User,)
    slug = models.SlugField(blank=True, editable=False)

    def __unicode__(self):
        return self.title

views.py:

(views.py：)

class RequestDetailView(ModelFormMixin, DetailView):
    model = Request
    form_class = RequestCommentForm

    def get_success_url(self):
        return reverse('request-detail', kwargs={'pk': self.object.pk})

    def get_context_data(self, **kwargs):
        context = super(RequestDetailView, self).get_context_data(**kwargs)
        context['form'] = self.get_form()
        return context

    def post(self, request, *args, **kwargs):
        self.object = self.get_object()
        form = self.get_form()
        if form.is_valid():
            return self.form_valid(form)
        else:
            return self.form_invalid(form)
    def form_valid(self, form):
        form.instance.author = self.request.user
        form.instance.request = Request.objects.get(pk=self.object.pk)
        form.instance.created = timezone.now
        form.save()
Also tried this part with:
        self.object = form.save(commit=False)
        self.object.author = self.request.user
        self.object.request = Request.objects.get(pk=self.object.pk)
        self.object.created = timezone.now
        self.object.save()
        return super(RequestDetailView, self).form_valid(form)

template: request_detail.html comments section .....

(模板：request_detail.html评论部分.....)

{% load bootstrap %}
<form action="{% url 'request-detail' object.id %}" method="post"> {% csrf_token %}
        <ul class="form-group">
        {{ form|bootstrap }}
        </ul>
        <input class="btn btn-primary" type="submit" value="Submit" />
</form>

.....

(.....)

Page renders correctly, but when I submit, no-go with saving comment.

(页面正确呈现，但是当我提交时，保存评论无法进行。)

Debug toolbar shows that sql queries are updating the request model, instead of request comment.

(调试工具栏显示sql查询正在更新请求模型，而不是请求注释。)

Can't figure out how to add simple comment form from different model to detail page.

(无法弄清楚如何从不同的模型向详细信息页面添加简单的注释表单。)

Any help would be appreciated.

(任何帮助，将不胜感激。)

Also, if there is more elegant way off adding comments form to class based view, would love to see it.

(另外，如果有更优雅的方法可以将注释表单添加到基于类的视图中，则希望看到它。)

My google-fu didn't help me to find anything.

Wish I could find a way to do this with CBV, but nope.. function view works great...

(希望我能找到一种使用CBV做到这一点的方法，但是不，..函数视图效果很好...)

class RequestDetailView(ModelFormMixin, DetailView):
    model = Request
    form_class = RequestCommentForm

    def get_success_url(self):
        return reverse('request-detail', kwargs={'pk': self.object.pk})

    def get_context_data(self, **kwargs):
        context = super(RequestDetailView, self).get_context_data(**kwargs)
        context['form'] = self.get_form()
        return context

    def comments(self):
        return RequestComment.objects.filter(request=Request.objects.get(pk=self.object.pk))


def RequestCommentAddView(request, pk):
    form = RequestCommentForm(request.POST or None)

    if form.is_valid() and pk:
        form.instance.author = request.user
        form.instance.request = Request.objects.get(pk=pk)
        form.save()
        return HttpResponseRedirect(reverse('request-detail', kwargs={'pk': pk}))
    return HttpResponseRedirect(reverse('request-detail', kwargs={'pk': pk}))
