问题 I have a C# program that inserts a pdf inside a MySQL database. Now I want to retrieve that pdf via django but django's models.FileField needs an "Upload To" parameter which means behind the scenes it actually stores the File on the file system rather than in the database. Is there any way I can set up a django model so that I can store the pdf directly inside MySQL? Regards 回答1: I have been dealing with this same issue, writing a pdf to a mediumblob field in mysql and retrieving via django.

Does anyone know if there's an out-of-the box way of storing images directly in the database vs. using ImageField model type that simply uploads it to the MEDIA_ROOT. And if there is, how does one serve those images then? Cheers No, there isn't. And for good reason. It's horribly inefficient to store and serve images from the database. Store them on the filesystem, and serve them directly from Apache. There is a nice solution here: http://djangosnippets.org/snippets/1305/ it stores content in a database blob. It seems there is no built-in BlobField in Django. However, there is one available

How do you store a "blob" of binary data using Django's ORM, with a PostgreSQL backend? Yes, I know Django frowns upon that sort of thing, and yes, I know they prefer you use the ImageField or FileField for that, but suffice it to say, that's impractical for my application. I've tried hacking it by using a TextField, but I get occassional errors when my binary data doesn't strictly confirm to the models encoding type, which is unicode by default. e.g. psycopg2.DataError: invalid byte sequence for encoding "UTF8": 0xe22665 Spacedman This snippet any good: http://djangosnippets.org/snippets/1597
