Hi, I am glad to introduce SQLAlchemy-ImageAttach, a new extension for attaching images to entity objects. It provides the following features:
- Storage backend interface: Yu can use file system backend on your local development box, and switch it to AWS S3 when it’s deployed to the production box. Or you can add a new backend implementation by yourself. - Maintaining multiple image sizes: Any size of thumbnails can be generated from the original size without assuming the fixed set of sizes. You can generate a thumbnail of a particular size if it doesn't exist yet when the size is requested. Use RRS (Reduced Redundancy Storage) for reproducible thumbnails on S3. - Every image has its URL: Attached images can be exposed as a URL. - SQLAlchemy transaction aware: Saved file are removed when the ongoing transaction has been rolled back. - Tested on various environments: Python 2.6, 2.7, 3.2, 3.3, PyPy / PostgreSQL, MySQL, SQLite / SQLAlchemy 0.8 or higher On the other hand, it does not provide: - General file attachment: It only supports images. - BLOB storage: It doesn’t use BLOB data type at all. - Image preprocessing: It simply does resizing, but any other image processings like crop aren’t provided. (Although you can do such things using Wand, SQLAlchemy-ImageAttach depends on.) Today I released SQLAlchemy-ImageAttach 0.8.0 which is its first stable version. You can install it using pip or easy_install: $ pip install SQLAlchemy-ImageAttach Docs and repository can be found at the following urls: https://sqlalchemy-imageattach.readthedocs.org/ https://github.com/crosspop/sqlalchemy-imageattach Please try it out and give me feedback! Thanks, Hong Minhee
