在帖子详细信息页面上插入评论表单。Django博客应用程序

Question

我已经试了2-3天了。我想在帖子详细信息页面上插入我的评论表单。 我的表格没有显示在那页上。 我遵循了本教程的注释模型。 我有另一个帐户应用程序，用于注册目的。 model.py

        class Post(models.Model):
        author = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE)
        title = models.CharField(max_length=200)
        text = models.TextField()
        created_date = models.DateTimeField(default=timezone.now)
        published_date = models.DateTimeField(blank=True, null=True)
        def __str__(self):
                return self.title
        def publish(self):
                self.published_date = timezone.now()
                self.save()
        def approved_comments(self):
            return self.comments.filter(approved_comment=True)       

class Comment(models.Model):
        post = models.ForeignKey('Post', on_delete=models.CASCADE, related_name='comments')
        author = models.CharField(verbose_name ='Username',max_length=200)
        text = models.TextField(verbose_name ='Comment')
        email = models.EmailField(default='')
        created_date = models.DateTimeField(default=timezone.now)
        approved_comment = models.BooleanField(default=False)

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

        def __str__(self):
            return self.text

view.py

def post_detail(request, pk):

    post = get_object_or_404(Post, pk=pk)
    return render(request, 'blog/post_detail.html', {'post': post})  


def add_comment_to_post(request, pk):
    post = get_object_or_404(Post, pk=pk)
    if request.method == "POST":
        form = CommentForm(request.POST)
        if form.is_valid():
            comment = form.save(commit=False)
            comment.post = post
            comment.save()
            return redirect('post_detail', pk=post.pk)
    else:
        form = CommentForm()
    return render(request, 'blog/add_comment_to_post.html', {'form': form})

@login_required
def comment_approve(request, pk):
    comment = get_object_or_404(Comment, pk=pk)
    comment.approve()
    return redirect('post_detail', pk=comment.post.pk)

@login_required
def comment_remove(request, pk):
    comment = get_object_or_404(Comment, pk=pk)
    comment.delete()
    return redirect('post_detail', pk=comment.post.pk)

url.py

path('post/<int:pk>/comment/', views.add_comment_to_post, name='add_comment_to_post'),
    path('comment/<int:pk>/approve/', views.comment_approve, name='comment_approve'),
    path('comment/<int:pk>/remove/', views.comment_remove, name='comment_remove'),
    path('post/<int:pk>/', views.post_detail, name='post_detail'),

请帮助我找到一种方法，将其插入我的post_deatil.html

如果您希望同一页面看到文章并添加评论，您只需要一个视图，如：

def post_details(request, pk):
post = get_object_or_404(Post, pk=pk)
if request.method == "POST":
    form = CommentForm(request.POST)
    if form.is_valid():
        comment = form.save(commit=False)
        comment.post = post
        comment.save()
        return redirect('post_detail', pk=post.pk)
else:
    form = CommentForm()
return render(request, 'blog/post_details.html', {'form': form, 'post': post})

然后，您的url将如下所示：

path('post/<int:pk>/', views.post_details, name='post-details'),

最后，您必须混合使用这两种模板，首先显示帖子的信息，然后在底部添加表单

这样，您就可以删除add_comment_to_post视图和url
