Question

我正在使用Django构建一个网站，我试图让用户上传要使用的图像，这是我的文件：

settings.py

# Absolute filesystem path to the directory that will hold user-uploaded files.
# Example: "/home2/media/media.lawrence.com/media/"
MEDIA_ROOT = os.path.join(BASE_DIR, 'static/media')

# URL that handles the media served from MEDIA_ROOT. Make sure to use a
# trailing slash.
# Examples: "http://media.lawrence.com/media/", "http://example.com/media/"
MEDIA_URL = '/media/'

models.py

class test1(models.Model):
    dress_name = models.CharField(max_length=250, default='dress')
    dress_size = models.CharField(max_length=50, default='5')
    docfile = models.FileField(upload_to='documents/%Y/%m/%d',default ='upload')

views.py

def home(request):
    all_dress = test1.objects.all()
    context = {
        'all_dress': all_dress,
    }
    return render(request, 'fostania/home.html', context)

以下是我在模板中使用它的方式

HTML

    {% for item in all_dress %}

        <div class="card" style="width: 18rem;">
  <img class="card-img-top" src="{{ item.docfile.url }}" alt="Card image cap">
  <div class="card-body">
    <h5 class="card-title">{{ item.dress_name }}</h5>
    <p class="card-text">{{ item.dress_size }}</p>
    <a href="#" class="btn btn-primary">Go somewhere</a>
  </div>
</div>
                              &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

      {% endfor %}

URLS.py

from django.contrib import admin
from django.template.context_processors import static
from django.urls import path
from django.contrib.auth import views as auth_views
from dress import settings
from fostania import views


urlpatterns = [
    path('admin/', admin.site.urls),
    path('login/', auth_views.login, name='login'),
    path('home/',views.home, name='home'),
    path('add/',views.add, name="add"),
] + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)

最后，图片永远不会显示..链接中始终是错误!!

请注意，图片在上传后会在静态/媒体文件中显示，所以我认为这是某种URL错误！

错误

错误是图像总是显示断开的链接，当我打开链接（打开图像链接）时，它会给我这个错误

Page not found (404)
Request Method: GET
Request URL:    http://127.0.0.1:8000/media/documents/2018/05/18/test_dress3.jpg

Answer 1

您需要将read()添加到项目的网址模式列表中：

MEDIA_URL

检查doc的相关部分。

Answer 2

<强>解决这是一个错误的导入参考，我使用from django.conf.urls.static import static而不是from django.template.context_processors import static并且它有效。

在Django中将图像添加到FileField
