网址指向同一地址后:
Forbidden (403)
CSRF verification failed. Request aborted.
You are seeing this message because this site requires a CSRF cookie when submitting forms. This cookie is required for security reasons, to ensure that your browser is not being hijacked by third parties.

解决方法:
在设置文件下注释:
'django.contrib.sessions.middleware.SessionMiddleware',
'django.middleware.common.CommonMiddleware',
#'django.middleware.csrf.CsrfViewMiddleware',
'django.contrib.auth.middleware.AuthenticationMiddleware',
'django.contrib.messages.middleware.MessageMiddleware',
'django.middleware.clickjacking.XFrameOptionsMiddleware',
新手报错
RuntimeError at /index
You called this URL via POST, but the URL doesn't end in a slash and you have APPEND_SLASH set. Django can't redirect to the slash URL while maintaining POST data.
Change your form to point to 127.0.0.1:8000/index/ (note the trailing slash), or set APPEND_SLASH=False in your Django settings.
解决方法,路由访问和提交要一致
片断
<form action="/index" method="post">
片断
path('index/',views.index)
安装xadmin时 编码出错:
"UnicodeDecodeError: 'gbk' codec can't decode byte 0xa4 in position 3444"
解决方法,手工下载,xadmin
网上搜索了一下,说是 python3 不支持 xadmin,结果还是找到了解决的方法
从错误中可以看到,是文件README.rst 出现了 Unicode 解码错误,这个文件时没有什么用处的,可以新建一个同名的空白文件替换掉
然后安装:
C:\WINDOWS\system32>pip install xadmin-master.zip
搞定。。
继随用户表后 后台增加数据时 报错 问题三
1452,'无法添加或更新子行:外键约束失败(`mxonline` .django_admin_log`,CONSTRAINT`django_admin_log_user_id_c564eba6_fk_auth_user_id` FOREIGN KEY(`user_id`)REFERENCES` auth_user`(`id`))')
在设置数据配置那儿加入红色部份,,
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql',
'NAME': 'mxonline',
'USER': 'root',
'PASSWORD': '142857',
'HOST': '127.0.0.1',
'PORT': '3306',
'OPTIONS': {
"init_command": "SET foreign_key_checks = 0;",
}
}
}

git 无法下载东西,报错:
fatal: open /dev/null or dup failed: No such file or directory
C:\Windows\System32\drivers\null.sys 从其他系统上拷贝一个过来覆盖,再启动 null 服务就正常了:
如何确定null.sys是否正常,很简单。实行如下命令:


C:\Users\Administrator>sc start null SERVICE_NAME: null
TYPE : 1 KERNEL_DRIVER
STATE : 4 RUNNING
(STOPPABLE, NOT_PAUSABLE, IGNORES_SHUTDOWN)
WIN32_EXIT_CODE : 0 (0x0)
SERVICE_EXIT_CODE : 0 (0x0)
CHECKPOINT : 0x0
WAIT_HINT : 0x0
PID : 0
FLAGS :

有一个更特么烦的报错可以让人自杀
在线安装xadmin时不响应,无反应,,,用下面的那个地址顺利解决
build_attrs() takes from 1 to 2 positional arguments but 3 were given
解决方法,更新到最新版本即可
djanao报错:
Make sure you've included captcha.urls as explained in the INSTALLATION section on
http://readthedocs.org/docs/django-simple-captcha/en/latest/usage.html#installation
解决方法:
url 视图增加相路由
path("captcha/", include('captcha.urls'))
问题之:
The view users.views.RegisterView didn't return an HttpResponse object. It returned None instead.
可能没有对应函数,检查vivew视图逻辑
问题:模板解释不了,原样输出
{% else %} 解决方法{% 不能有空格
Django2.0异常:Specifying a namespace in include() without providing an app_name is not supported.
因为django2.0以上变化了好多,需要在分发的路由上面指定一下指定的是那个路由 示例代码:
主路由:
path("org/", include('organization.urls',namespace="org")),
分发路由:红色那儿是重点,指点引用的app 名字
urlpatterns = [
path("list/", OrgView.as_view(),name = "org_list"),
]
app_name = "organization"
