推荐做ppt照片的网站seo怎么去优化

Django的一个优势就是有丰富的第三方包生态系统。这些由社区开发的包，可以用来快速扩展应用程序的功能集

1、安装Django Debug Toolbar

Django Debug Toolbar位于名列前三的第三方包之一
这是一个用于调试Debug Web应用程序的有用工具。该工具帮助我们了解应用的运行方式并发现问题。它通过提供面板来提供有关当前请求和响应的调试信息
在已激活的虚拟环境中运行以下命令来安装包

py -m pip install django-debug-toolbar

与django集成的第三方包需要一些安装后的设置，以将它们与我们的项目整合在一起。我们需要将包的Django应用程序添加到你的INSTALLED_APPS设置中。有些包需要其他更改，比如添加到我们的URL配置中。

在polls/settings中添加

在项目URLconf中添加：

添加中间件polls/settings

polls/settings

INTERNAL_IPS=["127.0.0.1",
]

如果要在项目中运行测试，则不应激活工具栏。你 可以通过添加另一个设置来执行此操作

polls/settings

TESTING="test"in sys.argv
if not TESTING:INSTALLED_APPS=[*INSTALLED_APPS,#* 符号用于将一个列表或元组中的所有元素解包，并将其插入到另一个列表或元组中"debug_toolbar",]MIDDLEWARE=["debug_toolbar.middleware.DebugToolbarMiddleware",*MIDDLEWARE,]

URLconf:

from django.conf import  settings
if not settings.TESTING:urlpatterns=[*urlpatterns,]+debug_toolbar_urls()

使用 * 将列表或元组中的元素作为单独的参数传递给函数：
def add(a, b, c): return a + b + c numbers = [1, 2, 3] result = add(*numbers) # 相当于 add(1, 2, 3) print(result) # 输出 6

使用 * 将一个列表或元组中的所有元素插入到另一个列表或元组中：
list1 = [1, 2, 3] list2 = [4, 5, 6] combined = [*list1, *list2] print(combined) # 输出 [1, 2, 3, 4, 5, 6]

总之最终的settings
