Flask Framework Cookbook - Second Edition

How to do it...

First, manually create a database in MongoDB using the command line. Let's name this database my_catalog:

>>> mongoMongoDB shell version: v4.0.4> use my_catalogswitched to db my_catalog

The following is an application that is a rewrite of our catalog application using MongoDB.

The first change comes to our configuration file, my_app/__init__.py:

from flask import Flask 
from flask_mongoengine import MongoEngine 
from redis import Redis 
 
 
app = Flask(__name__) 
app.config['MONGODB_SETTINGS'] = {'DB': 'my_catalog'} 
app.debug = True 
db = MongoEngine(app) 
 
redis = Redis() 
 
from my_app.catalog.views import catalog 
app.register_blueprint(catalog) 

Note that instead of the usual SQLAlchemy-centric settings, we now have MONGODB_SETTINGS ...
