    copied!<p>I'm trying to use django, and mongoengine to provide the storage backend only with GridFS. I still have a MySQL database.</p> <p>I'm running into a strange (to me) error when I'm deleting from the django admin and am wondering if I am doing something incorrectly.</p> <p>my code looks like this: </p> <pre><code># settings.py from mongoengine import connect connect("mongo_storage") # models.py from mongoengine.django.storage import GridFSStorage class MyFile(models.Model): name = models.CharField(max_length=50) content = models.FileField(upload_to="appsfiles", storage=GridFSStorage()) creation_time = models.DateTimeField(auto_now_add=True) last_update_time = models.DateTimeField(auto_now=True) </code></pre> <p>I am able to upload files just fine, but when I delete them, something seems to break and the mongo database seems to get in an unworkable state until I manually delete all FileDocument.objects. When this happens I can't upload files or delete them from the django interface.</p> <p>From the stack trace I have: </p> <pre><code>/home/projects/vector/src/mongoengine/django/storage.py in _get_doc_with_name doc = [d for d in docs if getattr(d, self.field).name == name] ... ▼ Local vars Variable Value _[1] [] d docs Error in formatting: cannot set options after executing query name u'testfile.pdf' self /home/projects/vector/src/mongoengine/fields.py in __getattr__ raise AttributeError </code></pre> <p>Am I using this feature incorrectly?</p> <h1><strong>UPDATE:</strong></h1> <p>thanks to @zeekay's answer I was able to get a working gridfs storage plugin to work. I ended up not using mongoengine at all. I put my adapted solution on <a href="https://github.com/madisona/django-mongo-storage" rel="noreferrer">github</a>. There is a clear sample project showing how to use it. I also uploaded the project to <a href="http://pypi.python.org/pypi/django-mongo-storage/" rel="noreferrer">pypi</a>.</p> <h1><strong>Another Update:</strong></h1> <p>I'd highly recommend the <a href="http://code.welldev.org/django-storages" rel="noreferrer">django-storages</a> project. It has lots of storage backed options and is used by many more people than my original proposed solution.</p>
