If we will do more abstraction as you suggest, we should rename its name first of all. :smile: Frankly I’ve been asked the same needs several times before, but currently have no idea how to achieve that.
I was thinking the same thing about the name change, but what you have going is nice and I didn't think it would be too hard to pull out the image specific functions of the Image
model/entity.
+1 for this

One way to implement this could be:
index
integer primary key column to File
, which the default query will be ordered by.Alright if I do this and submit a pull request?

@mwhite Yay, I’ll be pleased and review the patch if you submit it. Though the project name should be changed, too.
On second thought, maybe it would be better to have separate Video
and Document
classes which extend File
/Image
and have a ms
and page
integer property, respectively, to be more explicit.
Then a question would be whether to use joined table inheritance or one of the other inheritance schemes.
Another issue is if we include the ability to generate thumbnails for different types of videos and documents, which ones should have the external libraries be hard dependencies vs optional dependencies, and how to handle that.
Also, generating thumbnails might be something that should be a background task independent of the save transaction, so perhaps there should be a way to configure sqlalchemy-imageattach to do that with a task queue.
Michael,
that is way better. There's a lot of meta information that only makes sense for a given doc type. It could have a superclass that has no met info (beyond mime type) for those people who just want to attach files. (Dropbox use case)

+1 for this. I would love a generic file implementation.
I no longer have a need for this in my project so I probably won't be doing it like I said.
This library looks great and I was just thinking that it might be useful to abstract things a bit to allow for generic file attachments to a particular SQLAlchemy model/entity. Perhaps this can be achieved with the current API but I'm having a hard time seeing if its possible given the focus on images.
