Django窗體將不呈現（不反向匹配）

我試圖用Django 1.10創建一個窗體來創建一個任務對象的評論。當我想打開窗體，沒有現場，當我嘗試提交，我得到這個錯誤：Django窗體將不呈現（不反向匹配）

NoReverseMatch在/任務/ 29 /評論/ 反向與參數「create_comment」「（ ''，）' 未找到。 1個模式嘗試：[u'tasks /（？P [0-9] +）/ comment/$']

如何在我的模板上呈現我的表單並返回到我的「細節「提交後查看？

forms.py

class CreateCommentForm(forms.Form): 
    commentary = forms.CharField(label='Commentary', widget=forms.Textarea, required=True)

models.py

class Comment(models.Model): 
    user = models.ForeignKey(User, on_delete=models.CASCADE) 
    task = models.ForeignKey(Task, on_delete=models.CASCADE) 
    commentary = models.TextField(blank=True, max_length=5000) 
    created_at = models.DateTimeField(auto_now_add=True) 

def __str__(self): 
    return self.commentary

views.py

class CommentCreateView(SuperuserRequiredMixin, FormView): 
    template_name = 'tasks/create_comment_modal.html' 
    form_class = CreateCommentForm 

def form_valid(self, form): 
    user = self.request.user 
    task = Task.objects.get(id=self.kwargs['pk']) 
    commentary = form.cleaned_data['commentary'] 
    comment = Comment(user=user, task=task, commentary=commentary) 
    comment.save() 
    return HttpResponseRedirect(reverse('tasks:detail', kwargs={'pk': task.id}))

urls.py

url(r'^(?P<pk>[0-9]+)/$', views.DetailView.as_view(), name='detail'), 
url(r'^(?P<pk>[0-9]+)/comment/$', views.CommentCreateView.as_view(), name='create_comment'),

create_comment_modal.html

{% load widget_tweaks %} 
<form role="form" id="comment-create-form" name="comment-create-form" method="post" action="{% url 'tasks:create_comment' task.id %}"> 
<div class="modal-header"> 
    <button type="button" class="close" data-dismiss="modal">&times;</button> 
    <h4 class="modal-title">Add comment in task #{{ task.id }} - {{ task.title }}</h4> 
</div> 
<div class="modal-body"> 
    {% csrf_token %} 
    <div class="row"> 
     <div class="col-lg-12"> 
      <div class="form-group"> 
       <label class="control-label" for="{{ form.commentary.id_for_label }}">Commentary</label> 
       {% render_field form.commentary class+="form-control" %} 
      </div> 
     </div> 
    </div> 
    <div class="row"> 
     <div class="col-lg-12"> 
      <div id="current_user"> 
       Comment by : {{ user.first_name }} {{ user.last_name }} 
      </div> 
     </div> 
    </div> 
</div> 
<div class="modal-footer"> 
    <button type="button" class="btn btn-default" data-dismiss="modal">Cancel</button> 
    <button type="submit" class="btn btn-primary" value="deploy">Submit</button> 
</div> 
</form>

嘗試：高清get_success_url（個體經營）：回反向（ '任務：細節'，kwargs = { 'PK'：self.task.id}）在CommentCreateView –

的{% url 'tasks:create_comment' task.id %}表單裏面看起來很可疑。

您是否將task添加到CommentCreateView的上下文中？

以下行添加到您的CommentCreateView：

def get_context_data(self, **kwargs): 
    context = super().get_context_data(**kwargs) 
    context.update({'task': Task.objects.get(id=self.kwargs['pk'])}) 
    return context

謝謝你完美的作品！我用：context = super（CommentCreateView，self）.get_context_data（** kwargs） – dxtr69
