django外部キーの外部キーですが、管理ページに表示できません

Question

models.pyとviews.pyに問題があります。 コメントに返信を追加すると、「Dish_comment_reply_post」には何も表示されません。管理ページで自分で選択する必要があります。

class Dish_comment(models.Model): 
    Dish_comment_post=models.ForeignKey('dish.Dish_post', related_name='comments') 
    Your_name=models.CharField(max_length=200) 
    Content=models.TextField() 
    Dish_comment_created_date=models.DateField(default=timezone.now) 
    Dish_comment_approved=models.BooleanField(default=False) 

    def approve(self): 
     self.Dish_comment_approved=True 
     self.save() 

    def __str__(self): 
     return self.Content 

    def Dish_approved_comments(self): 
     return self.Dish_comment.filter(Dish_comment_approved=True) 

class Dish_comment_reply(models.Model): 
    Dish_comment_reply_post=models.ForeignKey('dish.Dish_comment', related_name='replies', null=True) 
    Your_name=models.CharField(max_length=200, default='abcd12345') 
    Content=models.TextField() 
    Dish_comment_reply_created_date=models.DateField(default=timezone.now) 

    def __str__(self): 
     return self.Content 

views.py：

def dish_add_comment_to_post(request,pk): 
    dish_post_from_db=get_object_or_404(Dish_post, pk=pk) 
    if request.method=="POST": 
     dish_comment_form=DishCommentForm(request.POST) 
     if dish_comment_form.is_valid(): 
      dish_comment_from_admin=dish_comment_form.save(commit=False) 
      dish_comment_from_admin.Dish_comment_post=dish_post_from_db 
      dish_comment_from_admin.save() 
      return redirect('dish.views.dish_detail', pk=dish_post_from_db.pk) 
    else: 
     dish_comment_form=DishCommentForm() 
    return render(request, 'dish/dish_add_comment_to_post.html', {'dish_comment_form': dish_comment_form})

    dish_comment_from_db.delete() 
    return redirect('dish.views.dish_detail', pk=dish_post_pk) 

def dish_add_reply_to_comment(request, pk1, pk2): 
    dish_post_from_db=get_object_or_404(Dish_post, pk=pk1) 
    dish_comment_from_db=get_object_or_404(Dish_comment, pk=pk2) 
    if request.method=="POST": 
     dish_reply_form=DishCommentReplyForm(request.POST) 
     if dish_reply_form.is_valid(): 
      dish_reply_from_admin=dish_reply_form.save(commit=False) 
      dish_reply_from_admin.Dish_comment_reply_post=dish_comment_from_db

    else: 
     dish_reply_form=DishCommentReplyForm() 
    return render(request, 'dish/dish_add_reply_to_comment.html', {'dish_reply_form': dish_reply_form})

変更 Dish_comment_post=models.ForeignKey('dish.Dish_post', related_name='comments') Dish_comment_reply_post=models.ForeignKey('dish.Dish_comment', related_name='replies', null=True)感謝
