Python 使用Django模型中的数据在我的主页上显示图像

希望简单地显示通过

Admin

在

UL

标记之间的模板文件中输入的模型数据中的多张图片。我无法渲染数据以显示图像。我不需要在

URL.py中发送任何东西，只需要先污染我主页上的图像。有人能帮我解决问题吗？谢谢大家!

这段代码中有一些奇怪的东西

首先，你想对所有的产品做点什么。那么，为什么要使用DetailView来选择和显示单个项目呢？您需要使用ListView，它将传递产品列表

第二，出于某种原因，您将
上下文\u对象\u名称
重写为“任务”。但是，在模板中，您迭代“产品”——一个没有提供的名称。如果您已将上下文对象称为“任务”，那么您应该迭代它。
了解我做错了什么

显然，我需要进入我的url并更改第一个
url元组中已经存在的
TemplateView
：

from django.conf.urls import patterns, include, url
from django.conf import settings
from django.conf.urls.static import static
from django.views.generic import TemplateView

from django.contrib import admin

urlpatterns = patterns('',
url(r"^$", TemplateView.as_view(template_name="homepage.html"), name="home"),

url(r'^admin/', include(admin.site.urls)),
url(r"^account/", include("account.urls")),
url(r'^likes/', include('likes.urls')),
)

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

并将
URL元组
更改为
列表视图
，以从我的django模型生成图像

from django.conf.urls import patterns, include, url
from django.conf import settings
from django.conf.urls.static import static
from django.views.generic import ListView
from products.models import Product

from django.contrib import admin


urlpatterns = patterns('',
    url(r"^$", ListView.as_view(
        template_name="homepage.html",
        model = Product,
        context_object_name = "products",
        ), name="home"),

    url(r'^admin/', include(admin.site.urls)),
    url(r"^account/", include("account.urls")),
    url(r'^likes/', include('likes.urls')),
)

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

谢谢你的更正！基于这个建议，我能够解决这个问题！
