Question

我正在尝试在我的主页上随机显示视频。用户能够上载视频，该视频将被保存到媒体/文档中的文档以及数据集中。我尝试了下面的代码，但它一直给我一个错误，

Exception Type: TemplateSyntaxError at /
Exception Value: 'media' is not a registered tag library. Must be one of:
admin_list
admin_modify
admin_static
admin_urls
cache
i18n
l10n
log
static
staticfiles
tz

我从urls.py中删除了settings.DEBUG:，并将.url添加到了{% media 'doc.document.url' %}，但这是行不通的。

home.html

{% load media %}
    {% for doc in document %}
     <video width='320' height= '240' controls>
      <source src="{% media 'doc.document.url' %}" type='video/mp4'>
      Your browser does not support the video tag.
     </video>
    {% endfor %}

models.py

from django.db import models
from datetime import datetime
from django.contrib.auth.models import User
from django.conf import settings
...
class Document(models.Model):
    title = models.CharField(max_length=100, default='NoTitle')
    description = models.CharField(max_length=255, blank=True)
    document = models.FileField(upload_to='documents/')
    uploaded_at = models.DateTimeField("date published")#(auto_now_add=True)

    creator = models.ForeignKey('auth.User', on_delete=models.CASCADE, blank=True, null=True)

    def __str__(self):
        return self.title

urls.py

urlpatterns = [
    path('admin/', admin.site.urls),
    path("", views.homepage, name="homepage"),
    path("myconta/", views.myconta, name="myconta"),
    path("upload/", views.model_form_upload, name="upload"),
    path("register/", views.register, name="register"),
    path('', include("django.contrib.auth.urls")),
]

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

views.py

def homepage(request):
    return render(request=request, template_name="main/home.html", context={"sites": Info.objects.all})
    return render(request=request, template_name="main/home.html", context={"document": Document.objects.all})

STATIC_URL = '/static/'

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

home.html

{% load media %}
    {% for doc in document %}
      <video width='320' height= '240' controls>
      <source src="{{ MEDIA_URL }} {{ doc.document.url }}" type='video/mp4'>
      Your browser does not support the video tag.
      </video>
    {% endfor %}

settings.py

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