How to modify data sent back to phone

[Alex Little]

Question from an email I received:

I wanted know how I can modify the data that is sent to the phone when a user logs in to oppia

And my reply:

For modifying the the data sent back to the phone after login, you can edit the UserResource API (see: https://github.com/DigitalCampus/django-oppia/blob/master/oppia/api/resources.py). Just to explain how this works for the points:

• Add an extra field in the class (see line 56 of the above code link)
• In the Meta section, under the "fields" list (line 66) add this new field
• Add a 'dehydrate_points' method (lines 106-108) - this determines what actual data is going to be sent back.
  

You can change the TrackerResource in a similar way if there is data you'd like to return every time a tracking activity is sent back to the server (this class starts at line 279 - and also sends back the points so they can be updated on the phone display)

Am posting here in case this info is useful to others,
Cheers,
