Flask-Download-Btn
Flask-Download-Btn defines a SQLALchemy Mixin for creating Bootstrap download buttons in a Flask application.
Its key features are:
- Automatic enabling and disabling: A download button is automatically disabled on click and re-enabling on download completion.
- Web form handling: Applications can modify a download button on click based on web form responses.
- 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. 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:
@app.route('/')
def index():
btn = DownloadBtn.query.filter_by(name='example1').first()
if not btn:
btn = DownloadBtn()
btn.name = 'example1'
btn.text = 'Download Example 1'
btn.filenames = ['hello_world.txt']
db.session.add(btn)
db.session.commit()
return render_template('index.html', download_btn=btn)
