Question

我正在尝试添加注释部分，以便使用Django在我的博客详细信息中添加注释部分，但是当我运行服务器时，开发服务器中没有出现错误，并且注释未显示。我从我的管理站点添加了评论。我的代码段如下。

views.py

from .models import Post
from django.utils import timezone
from .forms import PostForm, CommentsForm
from  django.contrib.auth.decorators import user_passes_test
# Create your views here.


def home(request):
    return render (request, 'blogapp/home.html')

def blog_list(request):
    post = Post.objects.order_by('-published_date')
    context = {
        'posts':post
    }
    return render(request, 'blogapp/blog_list.html', context)

def blog_detail(request, pk=None):
    detail = Post.objects.get(pk=pk)
    context = {
        'detail': detail
    }
    return render(request, 'blogapp/blog_detail.html', context)


def add_post(request, pk=None):

    if request.method == "POST":
        form = PostForm(request.POST)
        if form.is_valid:
            body = form.save(commit=False)
            body.published_date = timezone.now()
            body.save()
            return redirect('blog_list')
        form = PostForm()
    else:
        form = PostForm()

    context = {
        'form': form
    }
    return render(request, 'blogapp/add_post.html', context)

def add_comments(request, pk=None):
    if request.method == "POST":
        form = CommentsForm(request.POST)
        if form.is_valid:
            comment = form.save(commit=False)
            comment.date_added = timezone.now()
            comment.save()
            return redirect('blog_detail')
        form = CommentsForm()
    else:

Answer 1

在您使用的模板中 {% for comment in post.comments.all %} 但是在模板上下文中没有post变量您应该使用{% for comment in detail.comments.all %}
