      4. Add 3 questions to the quiz:
        • 1: Essay configured to use "HTML Editor" as response format, "Allow attachments" set to NO

        • 3: Numerical
      5. Access with the student user u1 to the site, go to the course and open the quiz
      6. Add some text in the first question, attach a file in the second question and reply the last question
      7. Click "Finish attempt" and nothing else, you will see the summary of the attempt
      8. In the browser URL you will see an URL like this: mod/quiz/summary.php?attempt=X&cmid=Y. You have to copy the X value somewhere because you will use it later
      9. Create a Token in the mobile app service for the user1 in the site (not an admin account)
        • Click on Site administration ► Plugins ► Web services ► Manage tokens
      10. Open the console an execute this new curl request, replacing wstoken with the token you just created and the site url with yours. the ATTEMPT_ID value has to be replaced with the attempt value (the X value) you annotated before

        curl 'http://localhost/m/stable_master/webservice/rest/server.php?moodlewsrestformat=json' --data 'wsfunction=mod_quiz_get_attempt_summary&wstoken=3af67232a7596ceb658df4db329e5ad6&attemptid=ATTEMPT_ID' | python -m "json.tool"

      11. Confirm that:
        • In the curl request response (that is huge) you will see that 3 questions are returned
        • For the first two questions, the essay ones, you will see a "settings" field (json formatted) containing an array of configuration options with different values
        • In the first question, the settings->responseformat will be set to editor

      This web service is used when rendering quiz questions in the mobile app. However, at present it just returns the rendered HTML of the question. It does not return any of the question options as structured data. (This was discussed, long ago, in https://moodle.org/mod/forum/discuss.php?d=382348.)

      For example, the essay question type is not returning the file extensions allowed to be submitted as part of the user's response.

      However, the was this web service is designed to work, it must only send data that the student is allowed to know. So, for example, it would be wrong to sent the entire question_definition object data, because that includes things such as the right answer, and all feedback, which the student should to be able to see until the question is finished.

      Therefore, in order to fix this, we need a new method on the question class, to return the important options for the question in its current state, but without giving away any inappropriate information to a student who accessed the raw data.
