CMI learner_id/student_id not supported

[TakeshiDaveau]

Hi guys,

Is this package support CMI event listed here : https://scorm.com/scorm-explained/technical-scorm/run-time/run-time-reference/ ?
I juste tested it and I can't access the learner_id/student_id

If not is there any means to get the student id ?

Thanks in advance

Since the edx_xblock_scorm does not support learner_id/student_id when playing a scorm file. I suggest for short term solution to fix this issue in the SCORM package, we can use cookie to store student_id based on generated a random UUID.

The code like this

genID: function() {
    var S4 = function () {
        return (((1 + Math.random()) * 0x10000) | 0).toString(16).substring(1);
    };
    return (
        S4() +
        S4() +
        "-" +
        S4() +
        "-" +
        S4() +
        "-" +
        S4() +
        "-" +
        S4() +
        S4() +
        S4()
    );
},

 setCookie: function (key, value, exp) {
    let date = new Date();
    date.setTime(date.getTime() + (exp * 24 * 60 * 60 * 1000));
    const expires = "expires=" + date.toUTCString();
    document.cookie = key + "=" + value + "; " + expires + "; path=/;";
},

getCookie: function(key) {
    const name = key + "=";
    const decode = decodeURIComponent(document.cookie);
    const arr = decode.split('; ');
    let res;
    arr.forEach(val => {
        if (val.indexOf(name) === 0) {
            res = val.substring(name.length);
        }
    })
    return res;
  }
};

if (!getCookie('student_anonymous_id')) {
    setCookie('student_anonymous_id', genID(), 30);
}

We can get a student_id like this

student_id: LMSGetValue('cmi.core.student_id') || getCookie('student_anonymous_id'),

Or change to use localStorage to avoid 3rd cookie blocking issue with browser

Since this is an open source package I already did a pull request #26 and I modify by myself the package before uploading it on OpenEDX.

You solution is not a quick fix at all since it will only keep the student ID on 1 device/browser. What a poor experience for a student to lose is progress every time he changes device.

But I don't care anymore about this so I close this issue
