Question

我正在关注构建Web应用程序的Django书。当我构建一个模板时，除了我的图像之外，我得到的结果与书的结果相同 - 它们不存在。

我想知道是什么导致了这个问题。图像具有正确的URL，但是当我尝试打开它们时，Django声明＆＃34; Page NOT 404 404＆＃34;。

我正在粘贴下面的相关代码。另外，我包含了我的目录树的屏幕截图。

店/ models.py：

class Product(models.Model):
    category = models.ForeignKey(Category,
                                 related_name='products')
    name = models.CharField(max_length=200, db_index=True)
    slug = models.SlugField(max_length=200, db_index=True)
    image = models.ImageField(upload_to='products/%Y/%m/%d',
                              blank=True)

    description = models.TextField(blank=True)
    price = models.DecimalField(max_digits=10, decimal_places=2)
    stock = models.PositiveIntegerField()
    available = models.BooleanField(default=True)
    created = models.DateTimeField(auto_now_add=True)
    updated = models.DateTimeField(auto_now=True)

模板：

<a href="{{ product.get_absolute_url }}">
                <img src="  {% if product.image %}
                                {{ product.image.url }}
                            {%else %}
                                {% static 'img/no_image.png' %}
                            {% endif %}
                ">
           </a>

views.py

def product_list(request, category_slug=None):
    category = None
    categories = Category.objects.all()
    products = Product.objects.filter(available=True)
    if category_slug:
        category = get_object_or_404(Category, slug=category_slug)
        products = products.filter(category=category)
    return render(request, 'shop/product/list.html',
                            {'category': category,
                            'categories': categories,
                            'products': products})

修改（settings.py和urls.py）：

# Static files (CSS, JavaScript, Images)
# https://docs.djangoproject.com/en/1.10/howto/static-files/

STATIC_URL = '/static/'

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

urls.py

from django.conf.urls import url, include
from django.contrib import admin
from django.conf import settings
from django.conf.urls.static import static

urlpatterns = [
    url(r'^admin/', admin.site.urls),
    url(r'^shop/', include('shop.urls', namespace='shop')),
    url(r'^cart/', include('cart.urls', namespace='cart')),

]

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

从Django中的应用程序提供静态图像
