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.
This is the main edX platform which consists of LMS and Studio.
