Hello everyone,
Whenever I open a Learners Engagement page for any particular course in
Insights(*hawthorn.master*), it internally calls analytics-data-api
endpoint at */api/v0/course_learner_metadata/{course_id}* and endpoint
returns JSON response containing a “date_range” under a
“engagement_ranges”. (*Note:* I checked edx-analytics-api documentation (
https://edx.readthedocs.io/projects/edx-data-analytics-api/en/latest/) but,
I didn’t found API reference for same.)
So, If any learner engagement found during a week for a particular course,
it gives date_range object with a valid date as follows:
“engagement_ranges”: {
“date_range”: {
“start”: “2019-07-24”,
“end”: “2019-07-31”
},
…
}
But if there is no learners activity/engagement found during a week for any
particular course, it gives date_range objects with start_date and end_date
as a null value.
“engagement_ranges”: {
“date_range”: {
“start”: null,
“end”: null
},
…
}
Above response is parsed by backbone js located at
*edx-analytics-dashboard/analytics_dashboard/static/apps/learners/roster/views/activity-date-range.js*
and
if date_range has a *start* and *end* in response then data is parsed using
Utils.formatDate() so if the date is null it gives invalid date as a
response and final string is “*Activity between Invalid date - Invalid date*
”.

There should be a condition like, if “start” and “end” is available in
“date_range” dict and they have a valid date, then it should proceed to
parse, else it executes else condition from ternary expression and returns
“n/a” so final string should be “*Activity between n/a - n/a*” as per
backbone test cases.
Current Codebase:
return {
startDate: _(dateRange).has(‘start’) ?
Utils.formatDate(dateRange.start) : naText,
endDate: _(dateRange).has(‘end’) ? Utils.formatDate(dateRange.end) :
naText
};
It should be as following:
return {
startDate: _(dateRange).has(‘start’) and ! _.isNull(dateRange[‘start’])
? Utils.formatDate(dateRange.start) : naText,
endDate: _(dateRange).has(‘end’) and ! _.isNull(dateRange[‘end’]) ?
Utils.formatDate(dateRange.end) : naText
};
Please help me with this ASAP.
