# Flask-Download-Btn Flask-Download-Btn defines a [SQLALchemy Mixin](https://docs.sqlalchemy.org/en/13/orm/extensions/declarative/mixins.html) for creating [Bootstrap](https://getbootstrap.com/) download buttons in a [Flask](https://palletsprojects.com/p/flask/) application. Its key features are: 1. *Automatic enabling and disabling*: A download button is automatically disabled on click and re-enabling on download completion. 2. *Web form handling*: Applications can modify a download button on click based on web form responses. 3. *Progress bar*: Download buttons report progress using a progress bar updated with server-sent events. ## Example: Basic use Suppose we want to include a download button which downloads `hello_world.txt` accessible at `HELLO_WORLD_URL`. On click, we want to disable the button and re-enable it when the file finishes downloading. After setup, we can achieve this with the following: ```python @app.route('/') def index(): btn = get_btn('basic') if not btn: btn = DownloadBtn() btn.downloads = [(HELLO_WORLD_URL, 'hello_world.txt')] add_to_session(btn, 'basic') return render_template('index.html', download_btn=btn) ``` ## Documentation You can find the latest documentation at [https://dsbowen.github.io/flask-download-btn](https://dsbowen.github.io/flask-download-btn). ## License Publications which use this software should include the following citation for SQLAlchemy-Function and its dependencies, [SQLAlchemy-Function](https://dsbowen.github.io/sqlalchemy-function) and [SQLAlchemy-Mutable](https://dsbowen.github.io/sqlalchemy-mutable): Bowen, D.S.
