Using Google Apps Script to list assignments through Google Classroom API using course.coursework.list

Question

Inexperienced at this - please forgive any wrong choices of words...

I'm trying to use Google Apps Script to get a list of assignments set within different classrooms. I believe I have all the appropriate APIs, credentials and scopes required. I followed the tutorial for setting up a simple class list, which worked, then edited to try to list the assignments within each class as below:

/**  
 * Lists 100 course names and ids.
 */
function listCourses() 
{
  var optionalArgs = {
    pageSize: 100
  };
  var listArgs = {
    pageSize: 10
  };
  var response = Classroom.Courses.list(optionalArgs);
  var courses = response.courses;
  if (courses && courses.length > 0) 
  {
    for (i = 0; i < courses.length; i++) 
    {
      var course = courses[i];

      Logger.log('%s (%s)', course.name, course.id);

      var info = Classroom.Courses.CourseWork.list(listArgs);
      var works = info.works;
      if (works && work.length > 0) 
      {
        for (i = 0; i < works.length; i++) 
        {
          var work = works[i];

          Logger.log('%s (%s)', work.title, work.creationTime);
        }     
      }
    }
  }
}

Error was: Requested entity was not found. (line 22, file "Code")
*Line 22: var info = Classroom.Courses.CourseWork.list(listArgs);

Any ideas appreciated, thanks

Answer 1

This line: var info = Classroom.Courses.CourseWork.list(listArgs);

Should be: Classroom.Courses.CourseWork.list(courseId, optionalArgs)

Or this: Classroom.Courses.CourseWork.list(courseId)

The point is that courseId is required.

You can try it on the API Explorer Here.

So the code should look something like this:

function listCourses() {
  var optionalArgs = {pageSize: 100};
  var listArgs = { pageSize: 10 };
  var response = Classroom.Courses.list(optionalArgs);
  var courses = response.courses;
  if (courses && courses.length > 0) {
    for (i = 0; i < courses.length; i++) {
      var course = courses[i];
      Logger.log('%s (%s)', course.name, course.id);
      var info = Classroom.Courses.CourseWork.list(course.id, listArgs)
      var works = info.works;
      if (works && work.length > 0) {
        for (i = 0; i < works.length; i++) {
          var work = works[i];
          Logger.log('%s (%s)', work.title, work.creationTime);
        }     
      }
    }
  }
}

But check it out carefully because this is the first time I've ever enabled the Classroom API.
