django.template.exceptions.TemplateDoesNotExist: login.html 错误处理

登陆Login界面时候报错

Internal Server Error: /login/
Traceback (most recent call last):

django.template.exceptions.TemplateDoesNotExist: login.html

在setting.py下DIRS如下所示

TEMPLATES = [
    {
        'BACKEND': 'django.template.backends.django.DjangoTemplates',
        'DIRS': [],
        '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',
            ],
        },
    },
]

在setting.py重新设置下DIRS如下所示,则问题解决

TEMPLATES = [
    {
        'BACKEND': 'django.template.backends.django.DjangoTemplates',
#        'DIRS': [],
        'DIRS': ["%s/%s" %(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',
            ],
        },
    },
]

另外需要确保templates目录下确实是有login.html文件

[python@qinhan templates]$ pwd
/home/python/project/MyCrazyeyes/templates
[python@qinhan templates]$ ls
login.html
[python@qinhan templates]$
