Question

我刚刚开始学习django，但我一直坚持为博客上的登录用户创建评论部分，并让用户能够回复该评论。我正在使用基于类的视图，我想将注释添加到DetailView（以我的情况为PostDetailView）。

models.py

from django.db import models
from django.utils import timezone
from django.contrib.auth.models import User
from django.urls import reverse

class Post (models.Model):
    title = models.CharField (max_length=100)
    content = models.TextField ()
    date_posted = models.DateTimeField (default=timezone.now)
    author = models.ForeignKey(User, on_delete=models.CASCADE)
    image = models.ImageField(default='default.jpg', upload_to='blog_images', blank=True)

    def __str__(self):
        return self.title

    def get_absolute_url(self):
        return reverse('post-detail', kwargs={'pk': self.pk})

class Comment(models.Model):
    post = models.ForeignKey('blog.Post', on_delete=models.CASCADE, related_name='comments')
    author = models.ForeignKey(User, on_delete=models.CASCADE)
    content = models.TextField()
    date_posted = 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.content        

    def get_absolute_url(self):
        return reverse('post-detail', kwargs={'pk': self.pk})

views.py

from django.shortcuts import render, get_object_or_404, redirect
from django.contrib.auth.mixins import LoginRequiredMixin, UserPassesTestMixin
from django.contrib.auth.models import User
from django.views.generic import ListView, DetailView, CreateView, UpdateView, DeleteView
from .models import Post, Comment
from .forms import CommentForm
#from django.http import HttpResponse


def home(request):
    context = {
        'posts': Post.objects.all()
    }
    return render (request, 'blog/home.html', context)

class UserPostListView(ListView):
    model = Post
    template_name = 'blog/user_posts.html' # <app>/<mode>_<view_type>.html
    context_object_name = 'posts'
    paginate_by = 5

    def get_queryset(self):
        user = get_object_or_404(User, username=self.kwargs.get('username'))
        return Post.objects.filter(author=user).order_by('-date_posted')

class PostListView(ListView):
    model = Post
    template_name = 'blog/home.html' # <app>/<mode>_<view_type>.html
    context_object_name = 'posts'
    ordering = ['-date_posted']
    paginate_by = 5

class PostDetailView(DetailView):
    model = Post

class PostCreateView(LoginRequiredMixin, CreateView):
    model = Post
    fields = ['title', 'content', 'image']

    def form_valid(self, form):
        form.instance.author = self.request.user
        return super().form_valid(form)

class PostUpdateView(LoginRequiredMixin, UserPassesTestMixin, UpdateView):
    model = Post
    fields = ['title', 'content', 'image']

    def form_valid(self, form):
        form.instance.author = self.request.user
        return super().form_valid(form)

    def test_func(self):
        post = self.get_object()
        if self.request.user == post.author:
            return True
        return False    

class PostDeleteView(LoginRequiredMixin, UserPassesTestMixin, DeleteView):
    model = Post
    success_url = '/'

    def test_func(self):
        post = self.get_object()
        if self.request.user == post.author:
            return True
        return False        

def about(request):
    return render (request, 'blog/about.html', {'title': 'About'})

如果有人可以帮助我，我将不胜感激。谢谢
