Python SQL with NoSQL
NOTE: DreamFactory Python scripting requires 'bunch' package to be installed on server.
sudo pip install bunch
This script runs after a GET on the service db at db/_table/contact. For each record in the response, it queries MongoDB to get another field, the Twitter handle for the contact. It adds that to the response as a field named 'from_mongo_twitter'. For this change to take effect, you have to enable modification of response in the Admin Console script editor. Check the box 'Allow script to modify request (pre-process) or response (post-process)'.
content = event.response.content; if content.resource != "": records = content.resource; for (i, record) in enumerate(records): # filter by email filter = "filter=" + "email=" + record.email; # get matching record from MongoDB service result = platform.api.get('/mongodb/_table/contact?'+filter); # convert json string -> dict -> bunch data = bunchify(json.loads(result.read())); # from_mongo_twitter can be a field in MySQL schema, but it doesn't have to be record.from_mongo_twitter = data.resource.twitter.encode('utf-8'); records[i] = record; event.response.content = records;
