Question

我认为这很简单，但我根本找不到错误。 for循环中的代码没有执行。当我查找数据库和管理站点时，内容显示正常，但尝试在HTML上显示不起作用：

浏览

    from django.shortcuts import render
    from django.utils import timezone
    from .models import Post
    def post_list(request):
        posts = Post.objects.filter(published_date__lte=timezone.now())
        return render(request, "blog/bloglist.html", {'posts': posts})

的url：

    from django.conf.urls import url
    import views

    urlpatterns = [
        url(r'^blog/$', views.post_list),

    ]

base.html文件

<!DOCTYPE html>
<html lang="en">
<head>
   <meta charset="UTF-8">
   <title>Blog</title>
</head>
<body>

    <h1>Base</h1>

            {% block content %}

            {% endblock  %}

 </body>
 </html>

bloglist.html

{% extends "base.html" %}

{% block content %}

    <h1>Blog </h1>
    {% for post in posts %}


            <h3>{{ post.title }}</h3>



    {% endfor %}
{% endblock %}

并确保模型也包含在内机型：

from django.db import models
from django.utils import timezone


# Create your models here.
class Post(models.Model):
    author = models.ForeignKey('auth.User')
    title = models.CharField(max_length=200)
    content = models.TextField()
    created_date = models.DateTimeField(default=timezone.now)
    published_date = models.DateTimeField(blank=True, null=True)

    def publish(self):
        self.published_date = timezone.now()
        self.save()

    def __str__(self):
        return self.title

我知道它非常简单，但我找不到错误。提前致谢
