django 开发遇到的问题

错误1：跨域请求
[22/Dec/2024 15:51:00] “POST /the_4/post_test/ HTTP/1.1” 403 2855

#原因 post操作时,暂时注释掉跨域请求
#需要注释掉中间件CsrfViewMiddleware 跨域请求
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',
]

错误2：模版渲染和模型应用需要注册APPS

#在settings中注册子应用
INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'the_5', #注册子应用
]

错误3：模版文件找不到
django.template.exceptions.TemplateDoesNotExist: templates.html

#在settings中添加模版文件路径
TEMPLATES = [
    {
        'BACKEND': 'django.template.backends.django.DjangoTemplates',
        'DIRS': [os.path.join(BASE_DIR,"templates")],#添加模版的路径
        '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',
            ],
        },
    },
]
