Django 无法添加所见即所得

Question

我正在尝试通过此链接在我的页面上实现所见即所得：https://www.geeksforgeeks.org/adding-wysiwyg-editor-to-django-project/ 我目前处于第 5 点，他们希望我在下面添加：

# add condition in django urls file
if settings.DEBUG:
    urlpatterns += static(settings.MEDIA_URL, document_root = settings.MEDIA_ROOT)

但是当我在上面添加时，我收到以下错误消息

File "C:\Download\Development\NowaStrona_Django\mysite\my_site\my_site\urls.py", line 6, in <module>
    path('', include('blog.urls')),
  File "C:\Download\Development\NowaStrona_Django\lib\site-packages\django\urls\conf.py", line 34, in include
    urlconf_module = import_module(urlconf_module)
  File "C:\Download\Development\NowaStrona_Django\lib\importlib\__init__.py", line 127, in import_module
    return _bootstrap._gcd_import(name[level:], package, level)

    urlpatterns += static(settings.MEDIA_URL, document_root = settings.MEDIA_ROOT)
NameError: name 'static' is not defined

我正在附加 urls.py:

from . import views
from django.urls import path

urlpatterns = [
    path('', views.PostList.as_view(), name='home'),
    path('<slug:slug>/', views.PostDetail.as_view(), name='post_detail'),

    ]
# to jest dla wysiwyg
  # add condition in django urls file

from django.conf import settings


if settings.DEBUG:
    urlpatterns += static(settings.MEDIA_URL, document_root = settings.MEDIA_ROOT)

你知道为什么我会收到粘贴错误消息吗？

Answer 1

您缺少导入语句

from django.conf.urls.static import static
