Check if student submitted assignment via Moodle web services - moodle

Question

I am trying to use the Moodle API (web services) to get information about (my) assignment submissions. I want to know whether I submitted an attempt for the assignment already or not. I am using the mod_assign_get_assignments function (which doesn't have too much documentation) and the results I get (when looking at the assignments portion of each course) are:
{
"id": 25960,
"cmid": 350053,
"course": 8013502,
"name": "\u05d4\u05d2\u05e9\u05ea \u05ea\u05e8\u05d2\u05d9\u05dc \u05d1\u05d9\u05ea 1",
"nosubmissions": 0,
"submissiondrafts": 0,
"sendnotifications": 0,
"sendlatenotifications": 0,
"sendstudentnotifications": 0,
"duedate": 1617566400,
"allowsubmissionsfromdate": 0,
"grade": 100,
"timemodified": 1615897679,
"completionsubmit": 1,
"cutoffdate": 1617569940,
"gradingduedate": 0,
"teamsubmission": 0,
"requireallteammemberssubmit": 0,
"teamsubmissiongroupingid": 0,
"blindmarking": 0,
"hidegrader": 0,
"revealidentities": 0,
"attemptreopenmethod": "manual",
"maxattempts": 1,
"markingworkflow": 0,
"markingallocation": 0,
"requiresubmissionstatement": 0,
"preventsubmissionnotingroup": 0
...irrelevant configuations
}
The above result is for an assignment I have already submitted.
An example of an assignment I did not submit is:
{
"id": 19764,
"cmid": 268225,
"course": 8013201,
"name": "\u05ea\u05d9\u05d1\u05ea \u05d4\u05d2\u05e9\u05d4 14",
"nosubmissions": 0,
"submissiondrafts": 0,
"sendnotifications": 0,
"sendlatenotifications": 0,
"sendstudentnotifications": 0,
"duedate": 1611693000,
"allowsubmissionsfromdate": 0,
"grade": 100,
"timemodified": 1610972842,
"completionsubmit": 0,
"cutoffdate": 1611694860,
"gradingduedate": 0,
"teamsubmission": 0,
"requireallteammemberssubmit": 0,
"teamsubmissiongroupingid": 0,
"blindmarking": 0,
"hidegrader": 0,
"revealidentities": 0,
"attemptreopenmethod": "manual",
"maxattempts": 1,
"markingworkflow": 0,
"markingallocation": 0,
"requiresubmissionstatement": 0,
"preventsubmissionnotingroup": 0
...irrelevant configuations
}
The only apparent difference between these (that might point to a way to check if I submitted it or not) is the completionsubmit property, but that cannot be the solution because a different assignment that I have submitted has it set to 0 (just like the one I didn't submit).
Does someone have an idea how I can solve this issue?
Thanks in Advance!
EDIT: mod_assign_get_submissions denies my access
{"assignments":[],"warnings":[{"item":"assignment","itemid":myitemname,"warningcode":"1","message":"No access rights in module context"}]}
I looked now into mod_assign_get_submission_status but it seems like it is only able to parse one assignment at a time, does anyone have a way to make this more efficient?

Answer 1

You could try using mod_assign_get_submissions instead to retrieve submissions to assignments. Available since Moodle 2.5
