Manual Configuration

This plugin requires the creation of a dedicated Moodle user and role, as well as the setup of the Moodle webservices for the archive worker.

Warning

This is the manual configuration process which can be quite involved. Please only use the manual configuration if you consider yourself an advanced user / Moodle administrator.

Automatic Configuration     Most users want to use the automated configuration instead.

Create Moodle User and Role

At first, a new Moodle user and a global role need to be created for the Quiz Archiver. It will be used by the archive worker service to access quiz data.

Create a designated Moodle user for the quiz archiver webservice

  1. Navigate to Site Administration > Users (1) > Accounts > Add a new user (2)
  2. Set a username (e.g. quiz_archiver) (3), a password (4), first and lastname (5), and a hidden email address (6)
  3. Create the user (7)

Configure Plugin Settings

Once the user, role, and webservice are created, the last step is to configure the quiz archiver plugin to use the created webservice and user.

  1. Navigate to Site Administration > Plugins (1) > Activity modules > Quiz > Quiz Archiver (2)
  2. Set worker_url (3) to the URL under which the quiz archive worker can be reached (e.g., http://quiz-archive-worker:5000 or http://127.0.0.1:5000)
  3. Select the previously created quiz_archiver webservice for webservice_id (4) from the drop-down menu
  4. Enter the user ID of the previously created Moodle user for webservice_userid (5). It can easily be found by navigating to the users profile page and inspecting the page URL. It contains the user ID as the id query parameter.
  5. (Optional) Specify a custom job timeout in minutes
  6. (Optional) Specify a custom Moodle base URL2.
  7. Save all settings and create your first quiz archive (see Usage).
  8. (Optional) Adjust the default capability assignments.

Next Steps

You finished the initial configuration of the quiz archiver plugin. You now can either directly start archiving quizzes (see Usage) or adjust the default plugin settings (see Job Presets / Policies).

Usage       Job Presets

  1. You can check all capabilities prior to role creation in the next step or by manually inspecting the role definition XML file (res/moodle_role_quiz_archiver.xml). ↩

  2. This is only required if you run the quiz archive worker in an internal / private network, e.g., when using Docker. If this setting is present, the public Moodle $CFG->wwwroot will be replaced by the internal_wwwroot setting. Example: https://your.public.moodle/ will be replaced by http://moodle.local/. ↩
