django显示用户上传的图片

Question

我有 ImageUploadField 我将图像保存在my_project/forum_attachments 目录中。

但是当我尝试显示它们并通过此链接查看时：http://127.0.0.1:8000/forum_attachments/1466786056166112161_Nrns2WL.jpg 我收到一个错误

找不到页面 (404) 请求方法：GET 请求 网址：http://127.0.0.1:8000/forum_attachments/1466786056166112161_Nrns2WL.jpg

我该怎么办？

UPD：urls.py：

urlpatterns = [
    url(r'^polls/', include('some_app.urls')),
    url(r'^$', views.index, name='index'),
    url(r'^admin/', admin.site.urls),
    url(r'^about/', views.about, name='about'),
    url(r'^login/$', auth_views.login, name='login'),

    url(r'^user_logout/$', views.user_logout, name='user_logout'),
    url(r'^index_old/', views.index_old, name='index_old'),
    url(r'^forum/', views.forum, name='forum'),
    url(r'^vip/', views.vip, name='vip'),
    url(r'^test/', views.test, name='test'),
    url(r'^forum_new/', views.forum_new, name='forum_new'),
]

Answer 1

第一次设置在settings.py：

MEDIA_URL = '/forum_attachments/'

然后在您的主要urls.py 中添加以下代码：

from django.conf.urls.static import static
from django.conf import settings

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

Answer 2

如果您没有在设置或本地设置文件中设置您的 MEDIA_URL 和 MEDIA ROOT，您应该按照以下步骤操作。

Settings.py

import os

BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))

PROJECT_PATH = os.path.abspath(os.path.dirname(__file__))

MEDIA_ROOT = os.path.join(PROJECT_PATH,'../media/')

MEDIA_URL = '/media/'

STATICFILES_DIRS = (
     os.path.join(BASE_DIR, 'static'),
)

STATIC_ROOT = os.path.join(os.path.dirname(BASE_DIR), 'static')

STATIC_URL = '/static/' 

现在在您的 Urls.py 中，执行以下操作：

from django.conf.urls.static import static

urlpatterns = [
    url(r'^polls/', include('some_app.urls')),
    url(r'^$', views.index, name='index'),
    url(r'^admin/', admin.site.urls),
    url(r'^about/', views.about, name='about'),
    url(r'^login/$', auth_views.login, name='login'),

    url(r'^user_logout/$', views.user_logout, name='user_logout'),
    url(r'^index_old/', views.index_old, name='index_old'),
    url(r'^forum/', views.forum, name='forum'),
    url(r'^vip/', views.vip, name='vip'),
    url(r'^test/', views.test, name='test'),
    url(r'^forum_new/', views.forum_new, name='forum_new'),
]+ static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)

'static' 被附加到 urlpatterns 中，因为您的 DEBUG 可能在 settings.py 中设置为 True。
