不幸的是这是真的。Django-ckeditor 没有为该问题提供任何内置解决方案。有关上传文件的信息不会存储在任何地方。

如果你想保留它们 - 你必须自己做！

使用覆盖的删除方法创建适当的数据模型（或使用任何现成的“智能字段”，它可以为您处理文件的删除，Django删除FileField）：

from django.db import models

class UploadedFile(models.Model):
    uploaded_file = models.FileField(upload_to=u"storage/")
    uploaded_at = models.DateField(editable=False, auto_now_add=True)

    def __str__(self):
        return os.path.basename(self.uploaded_file.path)

    def url(self):
        return self.uploaded_file.url

    def delete(self, *args, **kwargs):
        file_storage, file_path = self.uploaded_file.storage, self.uploaded_file.path
        super(UploadedFile, self).delete(*args, **kwargs)
        file_storage.delete(file_path)

提供您自己的“上传”（和可选的“浏览”）视图的实现，该视图将用于记住交易：

from django.conf import settings
from django.contrib.admin.views.decorators import staff_member_required
from django.views.decorators.cache import never_cache
from django.views.decorators.csrf import csrf_exempt
from ckeditor_uploader.views import upload, browse
from .models import UploadedFile
import re

@staff_member_required
@csrf_exempt
def ckeditor_upload_wrapper(request, *args, **kwargs):
    response = upload(request, *args, **kwargs)

    if b"Invalid" not in response.content:
        try:
            matched_regex = re.search("callFunction\(\d, '(.*)'\);", str(response.content))
            file_location = matched_regex.group(1).lstrip(settings.MEDIA_URL)
            UploadedFile(uploaded_file=file_location).save()
        except Exception:
            pass
    return response

@staff_member_required
@csrf_exempt
@never_cache
def ckeditor_browse_wrapper(request, *args, **kwargs):
    return browse(request, *args, **kwargs)

更改urls.py中的默认重定向：

...
from app.views import ckeditor_upload_wrapper, ckeditor_browse_wrapper

urlpatterns = [
    url(r'^admin/', admin.site.urls),

    #url(r'^ckeditor/', include('ckeditor_uploader.urls')),
    url(r'^ckeditor/upload/', ckeditor_upload_wrapper, name='ckeditor_upload'),
    url(r'^ckeditor/browse/', ckeditor_browse_wrapper, name='ckeditor_browse'),
    ...
]

就这样... 现在，如果您注册新的UploadedFile模型，您将能够直接从 Django 管理面板浏览、搜索和删除任何上传的图片。

（此解决方案是针对带有扩展名 django-ckeditor 5.3 的Django 1.10实现的）
