This restores functionality that has been broken since the introduction of
XModuleDescriptor/XModule proxying (part of the XBlock transition). It generates
a CSV of all answers for all content of type "problem" in a given course, with a
row per (problem part, answer). The format is:
url_name, display name, answer id, answer, count
Example values:
url_name = "7f1b1523a55848cd9f5c93eb8cbabcf7"
display name = "Problem 1: Something Hard"
answer id = i4x-JediAcdmy-LTSB304-problem-7f1b1523a55848cd9f5c93eb8cbabcf7_2_1
answer = "Use the Force"
count = 1138
Since it only grabs things of type "problem", it will not return results for
things like self/peer-assessments. Any Loncapa problem types will show up (so
multiple choice, text input, numeric, etc.)
Instead of crawling the course tree and instantiating the appropriate CapaModule
objects to grab state, this version draws directly from StudentModule. This lets
us skip a lot of processing and most importantly lets us generate the answer
distribution without causing side-effects (since XBlocks auto-save state). It
also lets us take advantage of a read-replica database if one is available, to
minimize locking concerns.
There are minor changes to the legacy dashboard around CSV charset encoding and
a change to OptionResponseXMLFactory to make it more unicode friendly. Answer
distribution output is now also sorted, to group together answers for the same
content piece.
Note that this does not introduce celery into the process. Answer distributions
are still only available for small courses.
This was originally created to fix [LMS-922], but it also addresses [LMS-811] and
possibly other areas in the legacy dashboard where CSV downloads break due to
character encoding issues.
Refactored stub services for style and DRY
Added unit tests for stub implementations
Updated acceptance tests that depend on stubs.
Updated Studio acceptance tests to use YouTube stub server; fixed failing tests in devstack.
Several templates used a variable set by the user (the request host header). This led to a vulnerability where an attacker could inject their domain name into these templates (i.e., activation emails). This patch fixes this vulnerability.
LMS-532
For seeing overview of system status, for deleting and loading
courses, for seeing log of git imports of courseware. Includes command
for importing course XML from git repositories.
Added a lot of tests for additional coverage with some minor fixes
those tests discovered
Replaced existing test_none_user_index_access_with_startdate_fails
test with new test now that the tested function has changed and
was causing the original test to fail.
