0daf31e5ad removed un-i18n-ed text extension. 
At least in case of Python the output is wrong anyway in quite a lot of cases.

41a61a8507 Fixed the destroy session logic. 
1. an exercise_id is provided ==> only the LtiParameter object for the current user, consumer, and exercise is deleted.
2. no exercise_id is provided ==> external user and consumer are removed from the session, all LtiParameter objects for this user and consumer are deleted.

This enables users to have several tabs with exercises open and submitting the results to the tool consumer.
When an exercise has been submitted, the user cannot use the back button to get back to CodeOcean and work on the submitted or any other exercise.
For now a warning has been added to the info text to tell users not to do this. (As the LtiParameters have been deleted, the points can no more be submitted to the consumer.)
@TODO disable/redirect back button?

edb813ab14 added separate value for the actual external_id of the external user. 2016-12-31 00:58:36 +01:00

f318c62818 session[:external_user_id] has a somewhat misleading name. 
As the tests fail however, when the value that  fits the name is entered, I switched it back to the old version.

TODO: migration /Users/groucho/Documents/HPI/workspace/Xikolo-CodeOcean/codeocean/db/migrate/20160204111716_add_user_to_code_harbor_link.rb
is broken. A reference is made to table users which does not exist.
Workaround: run rake db:schema:load before running db:migrate. Still this should be fixed.
