Flask Framework Cookbook - Second Edition

How to do it...

Integrating Whoosh with Flask using SQLAlchemy is pretty straightforward. Let's take a look:

1. First, provide the path to the Whoosh base directory where the index for our models will be created. This should be done in the application's configuration, that is, my_app/__init__.py:

app.config['WHOOSH_BASE'] = '/tmp/whoosh' 

You can choose any path you prefer, and it can be absolute or relative.

2. Next, make small changes to the my_app/catalog/models.py file to make the string/text fields searchable:

import flask_whooshalchemy from my_app import app class Product(db.Model): __searchable__ = ['name', 'company'] # ... Rest of code as before ... # class Category(db.Model): __searchable__ = ['name'] # ... Rest of code as before ... ...
