Affichage d'images dans Django - Configuration d'urls.py

Question

Je m'excuse si c'est un doublon. J'ai parcouru le web et essayé plusieurs solutions. J'ai construit un téléchargeur d'image qui télécharge les images au bon emplacement mais, je pense que j'ai quelque chose dans mon urls.py qui m'empêche d'afficher les images.

Les lignes commentées sont des tentatives que j'ai faites mais je n'ai pas de chance. 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'),] 

Vue:

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') 

code dans le modèle:

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

erreur habituelle je vois:

Answer 1

Regardez bien votre erreur stacktrace:

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

TypeError: vue doit être un appelable ou une liste/tuple dans le cas de include().

Django 1.10 ne vous permet de spécifier des vues sous forme de chaîne (par exemple 'django.views.static.serve') dans vos modèles d'URL.

La solution est de mettre à jour votre urls.py pour inclure la vue appelable. Cela signifie que vous devez importer la vue dans votre urls.py:

from django.views.static import serve 

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

Ceci est également indiqué dans the Django docs.
