飞天使-template模版相关知识

遇到报错django.template.exceptions.TemplateSyntaxError: ‘staticfiles’ is not a registered tag library. Must

ROOT_URLCONF = ''TEMPLATES = [{'BACKEND': 'django.template.backends.django.DjangoTemplates','DIRS': [os.path.join(BASE_DIR, 'templates')],'APP_DIRS': True,'OPTIONS': {'context_processors': ['django.template.context_processors.debug','django.template.context_processors.request','django.contrib.auth.context_processors.auth','django.contrib.messages.context_processors.messages',],#添加下面内容'libraries': { # Adding this section should work around the issue.'staticfiles' : 'django.templatetags.static',},},},
]
解决办法参考链接：https://www.cnblogs.com/yizhipanghu/p/15346297.html

html 模版中新增一个图片

    <div id="title"><div><img src="{% static "imgs/stu04.jpg" %}"></div><div>学生信息</div></div>
#STATICFILES_DIRS --- 全局变量定义了存储静态文件集合
STATICFILES_DIRS = [os.path.join(BASE_DIR, 'static'),os.path.join(BASE_DIR, 'abc'),os.path.join(BASE_DIR, 'app01', 'static')
]

url 跳转-A标签（链接）

        <div><div><a href="/"><img src="{% static "yk-logo-1220.png" %}"></a></div><div id="detail">综艺首页</div></div>```####  redirect 关键字处理跳转用户没有登陆直接跳转到登陆页面from django.shortcuts import render
from django.shortcuts import redirect# Create your views here.def index(request): # 首页# url记录登录名 --- ? username=aliceusername = request.GET.get("username")# 如果获取到username值，直接显示首页，获取不到；调到登录页if username:return render(request, 'index.html')else:# 跳转到登录页return redirect("/login/")

多app下的templates 环境准备

setting 里面设置
INSTALLED_APPS = ['django.contrib.admin','django.contrib.auth','django.contrib.contenttypes','django.contrib.sessions','django.contrib.messages','django.contrib.staticfiles','home','tv','movie',
]

多app下模块的应用

每个app 会有一个index.html ,多个app会出现重复情况
则每个app下面可以建立一个相同app名字，比如tv ，tv/index.html ,xx ，xx/index.html
