Question

如果这是重复，我道歉。我一直在网上搜索并尝试了多种解决方案。我已经构建了一个图像上传器，将图像上传到正确的位置但是，我想我的urls.py中有一些东西让我无法显示图像。

评论的线条是我的尝试，但我没有运气。 urls.py：

from django.conf.urls import url
from . import views
from django.conf import settings
from django.conf.urls.static import static
app_name = 'orders'
urlpatterns = [
url(r'^$',views.index,name='index'),
url(r'^invoice/$', views.invoice, name='invoice'),

url(r'^photo/$', views.UploadView.as_view()),
#static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT),
#static(r'^media/', document_root=settings.MEDIA_ROOT),
#url("^media/(?P<path>.*)$","django.views.static.serve",{"document_root": settings.MEDIA_ROOT}),


url(r'^catalog/$', views.catalog, name='catalog'),
url(r'^postStampsShipments/$', views.postStampsShipments, name='postStampsShipments'),
url(r'^catalog/(?P<SKU>[^/]+)/$', views.catalogDetail, name='catalogDetail'),
url(r'^catalogchange/(?P<SKU>[^/]+)/$', views.catalogChange, name='catalogChange'),
url(r'^updateOSTKCat/$', views.updateCatalogOSTK, name='OSTKCat'),

url(r'^items/$', views.item, name='items'),
url(r'^items/(?P<SKU>[^/]+)/$', views.itemDetail, name='itemDetail'),

url(r'^inventory/$', views.inventory, name='inventory'),
url(r'^inventoryChange/$', views.inventoryChange, name = 'inventoryChange'),

url(r'^test/$', views.test, name='test'),
url(r'^genBarcode/$', views.genBarcode, name='genBarcode'),
url(r'^barcode/$', views.barcode, name='barcode'),

url(r'^(?P<retailOrderNumber>[^/]+)/', views.orderDetail,name = 'Detail'),
url(r'^(?P<retailOrderNumber>[^/]+)/shipments/', views.shipments, name='shipments'),]

查看：

def itemDetail(request,SKU):
    edit = request.GET.get('edit','')
    itm = Item.objects.filter(SKU=SKU)[0]
    vendors = Vendor.objects.all()
    cat = Category.objects.all()
    template = loader.get_template('orders/itemDetail.html')
    context = {
        'itemDetail':itm,'SKU':SKU,'edit':edit,'vendors':vendors,'cat':cat
    }
return HttpResponse(template.render(context, request))

settings.py：

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

模板中的代码：

               <td>{% load static %}
                   {{ img.image.url }}
                   <img src="{{ img.image.url }}">
               </td>

我看到的常见错误：

仔细查看错误堆栈跟踪：

url(r'^media/(.*)$', 'django.views.static.serve',{'document_root':os.path.join(os.path.dirname(__file__), 'static')})

TypeError：对于include()，视图必须是可调用或列表/元组。

Django 1.10不再允许您在网址格式中将视图指定为字符串（例如'django.views.static.serve'）。

解决方案是更新您的urls.py以包含可调用的视图。这意味着您必须导入urls.py中的视图：

from django.views.static import serve

urlpatterns = [
    url(r'^media/(.*)$', serve, {'document_root':os.path.join(os.path.dirname(__file__), 'static')}),
    # ...
]

这也在the Django docs中说明。
