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=alice
username = 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
