From 509e7db7c487c20aeeac29eb644073fc628b447d Mon Sep 17 00:00:00 2001 From: John Baldwin Date: Wed, 9 Dec 2020 12:44:54 +0100 Subject: [PATCH 01/24] 0.4 LPO performance update - figures.compat This is some groundwork to improving the "learner-metrics" API endpoint. Added new function, 'course_grade_from_course_id' to figures.compat to simplify and abstract retrieving the course grade structure from CoureGradeFactory. Also started with moving edx-platform imports into compat from other modules to centralize the dependency on the platform to a single module. The goal is for figures.compat to serve as an adapter to direct access to platform code --- figures/compat.py | 17 +++++++++++++++++ figures/metrics.py | 1 - 2 files changed, 17 insertions(+), 1 deletion(-) diff --git a/figures/compat.py b/figures/compat.py index 1bcb29fe..a611afe8 100644 --- a/figures/compat.py +++ b/figures/compat.py @@ -11,6 +11,7 @@ # pylint: disable=ungrouped-imports,useless-suppression from __future__ import absolute_import +from figures.helpers import as_course_key class UnsuportedOpenedXRelease(Exception): @@ -52,6 +53,12 @@ class UnsuportedOpenedXRelease(Exception): from opaque_keys.edx.django.models import CourseKeyField # noqa pylint: disable=unused-import,import-error +# preemptive addition.

This model collects a snapshot of a learner's progress for a given course (an "enrollment"). It forms the foundation to speed up the 'learner-metrics' API endpoint by reducing the queries needed to collect data. Prior to this work, 'learner-metrics' needed to query the platform's CourseEnrollment model and find the most recent instance of Figures LearnerCourseGradeMetrics model (if it exists: The learner needs to make course progress for it to exist) for the course. All this is quite expensive. Included in this commit is the model, migration, admin update, EnrollmentDataFactory for tests and the most barebones of test cases specifically for the model.
