As we move toward a question bank model for questions, this relaxes the question belongs to a course idea by first simply searching for the question by name. If there is only one match then no problem. If there is more than one then the base course of the current user should be preferred to ensure backward compatibility.
first try to just get the question by name.
if there is more than one then use the course_id
prefer to use the assignment if it is there, but when adding a question by name it will not be in the assignment so this will fail and we fall back to using the course.

Create LTI Keys¶
Generate a consumer and a secret key. Store them in the database and associate this key with the course of the instructor. The course_lti_mamp may look a little superflous now, but I think it will grow. There is no real magic about the keys so using a UUID seems like just as good a solution as anything.
This API is triggered by the generateLTIKeys() function in admin.js and is one panel of the main admin page.
- Returns:
JSON: A JSON object with the keys
consumer = auth.user.course_name + "-" + str(uuid.uuid1())
secret = str(uuid.uuid4())
ltid = db.lti_keys.insert(consumer=consumer, secret=secret, application="runestone")

This displays the table that collects tickets across workers
for this to work you will need to add a row to auth_group with the role admins
In addition any user that you want to have access to these tracebacks will need
to have their user_id and the group id for admins added to the auth_membership table.
This will require some manual sql manipulation.
