将项目迁移至django2.X, 中间件提示错误为:
ERRORS:
?: (admin.E408) ‘django.contrib.auth.middleware.AuthenticationMiddleware‘ must be in MIDDLEWARE in order to use the admin application.
?: (admin.E409) ‘django.contrib.messages.middleware.MessageMiddleware‘ must be in MIDDLEWARE in order to use the admin application.
?: (admin.E410) ‘django.contrib.sessions.middleware.SessionMiddleware‘ must be in MIDDLEWARE in order to use the admin application.
以往django项目中settings的中间件默认书写格式为:
MIDDLEWARE_CLASSES = ( ‘django.contrib.sessions.middleware.SessionMiddleware‘, ‘django.middleware.common.CommonMiddleware‘, ‘django.middleware.csrf.CsrfViewMiddleware‘, ‘django.contrib.auth.middleware.AuthenticationMiddleware‘, ‘django.contrib.auth.middleware.SessionAuthenticationMiddleware‘, ‘django.contrib.messages.middleware.MessageMiddleware‘, ‘django.middleware.clickjacking.XFrameOptionsMiddleware‘, ‘django.middleware.security.SecurityMiddleware‘, )
使用新版Django创建一个新的项目, 中间件书写格式为:
MIDDLEWARE = [ ‘django.middleware.security.SecurityMiddleware‘, ‘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‘, ]
可以看到新版django修改了中间件的书写格式: 由元组转变为列表, 并移除了一个中间件, SessionAuthenticationMiddleware
修改书写格式以及变量名即可.
