This adds request caching to the following places:
* course expiration wrapper (displayed in Units)
* offer banner generation (displayed in Units)
* get_enrollment
* user_by_anonymous_id
* youtube_disabled_for_course
On a sample course with edx-val enabled, this reduced the queries
for a large sequence from 450 to 155.
This is a follow up from MST-16, which was commited
in 3858036a4e.
Changes:
* Enrich course teams_configuration from a plain Dict
to a custom XBlock field that uses the new TeamsConfig
wrapper class.
* Remove teams_conf property from course, as the previous
change made it redundant.
* Update teams_enabled implementation.
* Remove teams_max_size field from course, which is
no longer semantically correct, as max team size
is now defined on a teamset level.
* Remove teams_topics in order to discourage use of raw
teams config dict.
* Add convenience properties teamsets and teamsets_by_id
to course.
* Allow periods and spaces in teamset IDs to avoid breaking
existing course teams.
Some parts of the code still use the old raw config data
(identifiable by searching "cleaned_data_old_format"),
which we expect to be slowly factored away as we build
new teams features. MST-40 has been created to remove any
remaining references if necessary.
MST-18
* fix: bokchoy test
* fix: remove pdb break
* For all files, from __future__ import unicode_literals.
* Add @python_2_unicode_compatible to both models.
* Test six.string_type(obj) for both models.
Also, fix some new pylint warnings and improve model repr methods.
MST-24
Develop the capability to allow instructors to designate teams to have private discussions. This way, so non-teammembers cannot view discussion. And the intend is for course teams to manage the team membership as well.
MST-10
Request object was mocked but mocked value was never assigned.
In py2 moked object call is always successful. But in py3 if
value is not properly assigned it returns None. Causing the test
to fail. Removing the mocked object also fails the test so
removing it as broken test.
This reverts commit 3d2617983b.
The change was not quite right because the method six provides needs to
have `self` be passed in as well. See the docs here:
https://six.readthedocs.io/#unittest-assertions
Reverting for now and we can fix it in smaller chunks later.
