Python 名称错误：名称'；urlpatterns'；没有定义

我正在尝试使用“ImageField”显示图像

settings.py：

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

---

您需要先初始化

urlpatterns

。像

urlpatterns = []

然后，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

设置.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/"

在您的URL中写入此代码。py

尝试以下操作：

from django.contrib.staticfiles.urls import staticfiles_urlpatterns
urlpatterns += staticfiles_urlpatterns()

---

这给了我这样一个信息：“django.core.exceptions.impropertlyconfigured:Empty static prefix not allowed”您得到了什么错误？编辑我的ans，试试看

from django.contrib import admin
from django.conf.urls import include, url


urlpatterns=[
url(r'^admin/', include(admin.site.urls))
]
urlpatterns += static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)
urlpatterns += static(settings.STATIC_URL, document_root=settings.STATIC_ROOT)

from django.contrib.staticfiles.urls import staticfiles_urlpatterns
urlpatterns += staticfiles_urlpatterns()
