我正在做一个培训项目，遇到了一个问题。我尝试在主页面显示 "事件 "块和 "新闻 "块，但是当我运行循环周期时，只显示一个块，第二个块不显示。解释一下，谁知道我做错了什么。这个问题我已经解决了三天了。先谢谢谁能回复帮助
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
{% if post %}
{% for post in post %}
{{ post.title }}
{% endfor %}
{% else %}
<p>У вас нет материала</p>
{% endif %}
{% if event %}
{% for event in event %}
{{ event.name }}
{% endfor %}
{% else %}
<p>У вас нет материала</p>
{% endif %}
</body>

模型。
from django.db import models
from datetime import date
# Create your models here.
class Blog(models.Model):
"""Новости"""
title = models.CharField("Заголовок", max_length=100)
description = models.TextField("Описание")
descriptionTwo = models.TextField("Описание (второй абзац)", blank=True, default="")

def __str__(self):
return self.title
class Meta:

verbose_name_plural = "Новости"
class Event(models.Model):
"""События"""

管理员。
from django.contrib import admin
from .models import Blog, Event
# Register your models here.
admin.site.register(Event)
admin.site.register(Blog)
你需要一个包含上下文的视图，其中包含了 events 蚂蚁 posts
class EventView(View):
def get(self, request):
events = Event.objects.all()
posts = Blog.objects.all()
return render(request, "home/home_list.html", {"events": events, "posts":posts})
在模板中，在这两个地方循环
{% if posts %}
{% for p in posts %}
{{ p.title }}
{% endfor %}
{% else %}
<p>У вас нет материала</p>
{% endif %}
{% if events %}
{% for e in events %}
{{ e.name }}
{% endfor %}
{% else %}
<p>У вас нет материала</p>
{% endif %}
在每个循环中，为 "循环对象 "和你正在循环的listdictionary使用不同的名称。就像这样。
{% if post %}
{% for p in post %}
{{ p.title }}
{% endfor %}
{% else %}
<p>У вас нет материала</p>
{% endif %}
{% if event %}
{% for e in event %}
{{ e.name }}
{% endfor %}
{% else %}
<p>У вас нет материала</p>
{% endif %}
