python - 名称错误 : name 'urlpatterns' is not defined

Question

我正在尝试使用“ImageField”显示图像

from django.conf.urls.static import static
from django.conf import settings
urlpatterns += static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)

设置.py:

STATIC_URL = '/static/'
STATICFILES_DIRS = (
    os.path.join(BASE_DIR, "static"),
    )
MEDIA_ROOT = ''
MEDIA_URL = "/media/"

Answer 1

您需要首先初始化urlpatterns。就像，

urlpatterns = []

那么，你可以这样做，

urlpatterns += static(settings.STATIC_URL, document_root=settings.STATIC_ROOT)
urlpatterns += static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)

像这样设置你的settings.py，

STATIC_URL = '/static/'
STATICFILES_DIRS = (
    os.path.join(BASE_DIR, "static"),
    )
STATIC_ROOT = os.path.join(BASE_DIR, 'static/')
MEDIA_ROOT = os.path.join(BASE_DIR, 'media/')
MEDIA_URL = "/media/"
