python之如何在 Django 中使用来自数据库的路径在网页上呈现图像

所以我试图在网页上显示图像，我将数据库中的图像路径保存为 media/imagename 并在我的 html 页面中我这样做:

{% for stuff in profile %} 
    <div class="alert alert-success" role="alert"> {{ stuff.text }} </div> 
 
    <img scr='/Users/Username/PycharmProjects/social-django-1.9/mysite/media/media/{{ stuff.thumbnail }}' width="200"> 
 
{% endfor %} 

在我的 settings.py 中我这样做:

MEDIA_ROOT = os.path.join(PROJECT_ROOT, '/Users/Username/PycharmProjects/social-django-1.9/mysite/media/media') 

但是图像不显示。我在这里做错了什么？谢谢!

编辑:

#urls.py 
 from django.conf.urls import patterns, url 
 from django.conf import settings 
 
 from social import views 
 
 
 urlpatterns = [ 
 
 
# main page 
url(r'^$', views.index, name='index'), 
# signup page 
url(r'^signup/$', views.signup, name='signup'), 
# register new user 
url(r'^register/$', views.register, name='register'), 
# login page 
url(r'^login/$', views.login, name='login'), 
# user doesnt exist webpage 
url(r'^user-doesnt-exist/$', views.login, name='user-doesnt-exist'), 
#page to show that the password is incorrect 
url(r'^wrongpass/$', views.login, name='wrongpass'), 
#webpage to show an error when a user tries to input nothing in the fields when signing up 
url(r'^novalues/$', views.register, name='novalues'), 
# logout page 
url(r'^logout/$', views.logout, name='logout'), 
# members page 
url(r'^members/$', views.members, name='members'), 
#invites page 
url(r'^invites/$', views.invites, name='invites'), 
# friends page 
url(r'^friends/$', views.friends, name='friends'), 
# user profile edit page 
url(r'^profile/$', views.profile, name='profile'), 
# messages page 
url(r'^messages/$', views.messages, name='messages'), 
# Ajax: check if user exists 
url(r'^checkuser/$', views.checkuser, name='checkuser'), 
#commiting again 
 
 
] 
 
 
if settings.DEBUG: 
urlpatterns += patterns(''(r'^media/(P<path>.*)$','django.views.static.serve', 
                         {'document_root':settings.MEDIA_ROOT,'show_indexes':True})), 

请您参考如下方法:

尝试将您的 MEDIA_ROOT 设置为:

MEDIA_ROOT = os.path.join(BASE_DIR, 'social/static/social/media') 
 
MEDIA_URL = '/media/' 

并在你的项目urls.py文件中添加:

from django.conf import settings 
from django.conf.urls import patterns 
 
if settings.DEBUG: 
    urlpatterns += patterns('', (r'^media/(?P<path>.*)$', 'django.views.static.serve', {'document_root': settings.MEDIA_ROOT, 'show_indexes': True})) 

然后，在您的模板中像这样调用图像:

{% if stuff.thumbnail %} 
    <img src="{{ object.thumbnail.url  }}"> 
{% endif %} 

在 models.py 中:

image = models.ImageField(upload_to='images/')
