Question

我正在制作一个简单的应用程序（Django版本1.11 + python3.5 +）。我想在Django模型的主页（网络应用程序）上显示图像。我可以从Django管理面板成功上传。但图像无法正常呈现。图像未显示在主页中。这是我的HTML文件。

{% extends "shop/base.html" %}
{% block content_area %}
{% for name in products %}
<div class="col-lg-3 col-md-3">
    <div class="main_content_sidebar">
        <div class="content_title">
            <h2>{{name.product_name}}</h2>
        </div>
        <div class="image_space">
            <img src="{{name.product_image.url}}" class="img-thumbnail" alt="">
        </div>
        <div class="content_p">
            <p>Retail Price:{{name.product_retail_price}}</p>
            <p>Quantity: {{name.product_quantity}}</p>
            <p>Date: {{name.product_sell_date}}</p>
        </div>
    </div>
</div>
{% endfor %}
{% endblock %}

这是mysite（项目）＆gt;＆gt; urls.py

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

from django.conf import settings
urlpatterns = [
    url(r'^shop/',include('shop.urls')),
    url(r'^admin/', admin.site.urls),
]
if settings.DEBUG:
    urlpatterns += static(settings.MEDIA_URL,
                          document_root=settings.MEDIA_ROOT)

这是我的models.py文件。

class ProductsName(models.Model):
    product_name=models.CharField('name', max_length=50)
    product_retail_price=models.IntegerField('retail price TAKA')
    product_quantity = models.IntegerField('quantity')
    product_sell_date=models.DateTimeField('buy date', auto_now_add=True)
    product_image = models.ImageField(upload_to='upload/', blank=True, null=True)

    def __str__(self):
        return self.product_name

当我访问我的主页时，我看不到任何图像。但我看到图像链接如果我打开我的浏览器开发工具。 chrome dev tool

如果我点击chrome dev工具中的图片链接。我收到django doesn/t found that image url错误。

我的文件夹结构也是：

mysite的店 manage.py path_to db.sqlite3

问题是您的MEDIA_ROOT未被提供，Django无法附加正确的网址。在您的项目中，urls.py在最后添加以下内容：

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

在setttings.py中添加正确的路径：

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

从Django模型
