无法在 html 页面上显示来自数据库的图像

Question

我只看到带有 /media/image.jpg 等 url 的图标。我认为问题在 urls.py，但我不知道如何解决。有人可以帮助我吗？

settings.py:

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

models.py:

....
class Image(models.Model):
    product = models.OneToOneField(Product)
    top_image = models.ImageField(upload_to='media/', verbose_name ="Главное изображение")
    second_image = models.ImageField(blank = True, verbose_name = "Изображение 2")
    third_image = models.ImageField(blank = True, verbose_name = "Изображение 3")
    fourth_image = models.ImageField(blank = True, verbose_name = "Изображение 4")
    fifth_image = models.ImageField(blank = True, verbose_name = "Изображение 5")

    def __unicode__(self):
        return u'%s' % self.product

    class Meta():
        db_table = "Image"
...

articles.html

...
 {% for image in product_images %}
         <div>
            <img src="{{ image.top_image.url }}">
         </div>
         {% endfor %}
...

urls.py

from django.conf.urls import patterns, include, url

urlpatterns = patterns('',
    # Examples:
    # url(r'^$', 'mypoject.views.home', name='home'),
    url(r'^', 'article.views.articles'),
    )

Answer 1

/media/image.jpg是亲戚url。

要获得绝对 uri 你需要这样的东西 request.build_absolute_uri(obj.image.url)

您可以阅读更多信息here in the django docs

Answer 2

我认为您必须将此添加到您的 urls.py 文件中：

urlpatterns = patterns('',
    # ... the rest of your URLconf goes here ...
) + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)

请注意，您只能将其用于开发人员：Django doc
