MEDIA_ROOT = os.path.join(BASE_DIR, "media")  # 多媒體文件存放處
MEDIA_URL = "/media/"  # 這個會自動加在FileField的upload_to的前面

urls

from django.conf.urls import url
from django.contrib import admin
from django.urls import path
from django.views.static import serve

from quotation import settings

urlpatterns = [
    url(r'^media/(?P<path>.+)$', serve, {'document_root': settings.MEDIA_ROOT}),
    path('admin/', admin.site.urls),
]

• re_path就是用正則表示定義路徑
