Develop and Production
Production
In production, you need to add media directory in you web server.
Develop
To service the uploaded files need a helper function, where /media/ your settings app.config['THUMBNAIL_MEDIA_URL']:
from flask import send_from_directory
@app.route('/media/<regex("([\w\d_/-]+)?.(?:jpe?g|gif|png)"):filename>')
def media_file(filename):
return send_from_directory(app.config['THUMBNAIL_MEDIA_THUMBNAIL_ROOT'], filename)Option settings
If you want to store the thumbnail in a folder other than the THUMBNAIL_MEDIA_THUMBNAIL_ROOT, you need to set it manually:
app.config['THUMBNAIL_MEDIA_THUMBNAIL_ROOT'] = '/home/www/media/cache'
app.config['THUMBNAIL_MEDIA_THUMBNAIL_URL'] = '/media/cache/'
app.config['THUMBNAIL_STORAGE_BACKEND'] = 'flask_thumbnails.storage_backends.FilesystemStorageBackend'
app.config['THUMBNAIL_DEFAULT_FORMAT'] = 'JPEG'Migrate 0.X to 1.X
Since version 1.X all settings have a prefix THUMBNAIL_. Example: MEDIA_ROOT -> THUMBNAIL_MEDIA_ROOT.
