我的看法

from django.shortcuts import render
from django.views import generic
from .models import Post


# Create your views here.
class PostList(generic.ListView):
    queryset = Post.objects.filter(status=1).order_by('-created')
    template_name = 'index.html'

class PostDetail(generic.DetailView):
    model = Post
    template_name = 'post_detail.html'

我的博客/网址

from . import views
from django.urls import path


urlpatterns = [
    path('', views.PostList.as_view(), name='home'),
    path('<slug:slug>/', views.PostDetail.as_view(), name='post_detail')
]

网址

from django.contrib import admin
from django.urls import path
from django.contrib import admin
from django.urls import path, include

urlpatterns = [
    path('admin/', admin.site.urls),
    path('', include('blog.urls')),
]

如果未在视图中提供上下文，则在使用基于类的视图时，object_list是默认上下文。因此您可以将查询集迭代为object_list

           {% for post in object_list %}
            <div class="card mb-4">
                <div class="card-body">
                    <h2 class="card-title">{{ post.title }}</h2>
                    <p class="card-text text-muted h6"> {{ post.created}} </p>
                    <p class="card-text">{{post.content|slice:":200" }}</p>
                    <a href="{% url 'post_detail' post.slug  %}" class="btn btn-primary">Read More &rarr;</a>
                </div>
            </div>
            {% endfor %}
