The third sample is quite similar to the first Basic sample. It builds upon that sample to demonstrate how to make a series of Valence Learning Framework API calls and do some processing to accomplish a task that joins data together from several sources.

The sample assumes the calling user context is an instructor (and that in all course offering enrollments, the calling user is enrolled in an instructor role).

It uses the get my enrollments route to retrieve all the course offerings in which the calling user is enrolled. It then gets all the students enrolled in those course offerings with the get enrolled users for orgunit route. Finally, it retrieves all the final grades for all those enrolled students using the get final grades for user in orgunit route.

This sample shows you:

Walk-through. This sample provides new functionality built on a framework very similar to the first sample: through a simple-web form, you can authenticate and then wait a moment to retrieve and process all the students’ final grade values for the calling instructor user. Deploy the sample appropriate for the platform you want, and run it, and use it in the same fashion you did for the first sample:

  1. Click the Authenticate button.

    • The form redirects your browser to the D2L login page hosted on http://lms.valence.desire2learn.com.

    • Fill out your test user name and password for the service (authenticating yourself as a user), and click Login.

    • The service redirects you back to your sample web-form.

    • The form makes the calls and processing required to show you the aggregated final grade values for your calling user’s courses.

Python

This sample for the Python platform has the same requirements as the Python client library. You will also require the Bottle and Beaker Python packages, as the sample is implemented as a simple web services application in a Bottle framework using Beaker to manage session state data.

To install. First download the latest version of the Python sample. Then, unzip the contents into a temporary folder.

To run the sample. Run the finalGrades.py script within the appropriate sub-directory in the samples folder to start the Bottle web-service application. Then, in a web-browser, navigate to http://localhost:8080/start.
