Django 配置404页面

修改settings.py

DEBUG = False  # 开发环境下为True，此时我们改为False
ALLOWED_HOSTS = ['*']  # 访问地址，127.0.0.1，自己的ip，如172.21.21.21（随便写的），...

静态文件配置

STATIC_URL = '/static/'
STATIC_ROOT = os.path.join(BASE_DIR, 'static').replace('\', '/')

在settings.py文件目录中，添加文件view.py

# 404
def page_not_found(request, exception):
    return render(request, '404.html')

# 500
def page_error(request):
    return render(request, '500.html')

在settings.py文件目录中，修改文件urls.py

from django.conf.urls import url
from . import view

urlpatterns = [
    ...
]
handler404 = view.page_not_found
handler500 = view.page_error

可能会报错

ERRORS:
?: (urls.E007) The custom handler404 view 'index.views.page_not_found' 
does not take the correct number of arguments (request, exception).

System check identified 1 issue (0 silenced).
