提问by hln
Can someone help me with this issue: I have a Django porject,
有人能帮我解决这个问题吗：我有一个 Django 项目，
in settings.py
在设置.py
MEDIA_ROOT = 'C:/Users/hl/workspace/beer/media'
MEDIA_URL = '/media/'
STATICFILES_DIRS = (
'C:/Users/hl/workspace/beer/media'
)
and in models.py
并在models.py中
image1= models.ImageField(upload_to=settings.MEDIA_ROOT)
and in url.py
并在 url.py
(r'^media/(?P<path>.*)$', 'django.views.static.serve',{'document_root': settings.MEDIA_ROOT}),
in views
在视图中
def allBeer(request):
beers=Beer.objects.all().order_by("name")
context={'beers': beers}
return render_to_response('AllBeers.html',context,context_instance=RequestContext(request))
and in html
并在 html
{%for beer in beers %}
<p>
<a href="/beers/{{beer.slug}}/">
<img scr="{{beer.image1.url}}">{{beer}}
</a>
</p>
{% endfor%}
It has not problem to load images, but images wont show in html file. I have searched and read a lot from internet but I still couldn't figure out.
加载图像没有问题，但图像不会显示在 html 文件中。我已经从互联网上搜索并阅读了很多内容，但我仍然无法弄清楚。

# Always use forward slashes, even on Windows.
# Don't forget to use absolute paths, not relative paths.
os.path.join(SITE_ROOT, 'templates'),

You're messing with the srcattribute of the image. It should just be -
你搞乱src了图像的属性。应该只是——
<img src="{{beer.image1.url}}" /> <!-- from the media url -->
Don't add anything to the end - django know's the url to serve the image from - that's what the ImageField on the model does.
不要在最后添加任何内容 - django 知道提供图像的 url - 这就是模型上的 ImageField 所做的。
I don't know that there's actually anything wrong with your url conf, but the pattern recommended in the docsis -
我不知道你的 url conf 实际上有什么问题，但文档中推荐的模式是 -
from django.conf import settings
from django.conf.urls.static import static
urlpatterns = patterns('',
# ... the rest of your URLconf goes here ...
) + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)

the location of your images are important. it has to be in the static folder and that has to be defined in the settings.
图片的位置很重要。它必须在静态文件夹中，并且必须在设置中定义。
