An obvious step towards integration between Canvas and Ladok3 is to pre-create in Canvas columns for each of the "delmoment" of a course. In this way there is a one to one mapping to and from the parts of a course grade in both Ladok and Canvas.

This turns out to be easy to do using the Canvas API "Create a custom gradebook column" (https://canvas.instructure.com/doc/api/custom_gradebook_columns.html).

Using the program insert-column-1.py as follows:

./insert-column.py 699 PROJ1
'Fri Nov 25 16:29:18 2016'
('result of post creating custom column: '
 '{"id":5,"title":"PROJ1","position":1,"teacher_notes":false,"hidden":false}')
('result of inserting the item into the module: '
 '{"id":5,"title":"PROJ1","position":1,"teacher_notes":false,"hidden":false}')
inserted column
True
'Fri Nov 25 16:29:18 2016'
'\n--DONE--\n\n'

Note that the program could easily be modified to put the new column at a particular position, rather than simply inserting the column as the first column. Ideally, the program would take the column names from KOPPS.

A disadvantage of custom columns seems to be that the gradebook export/import functions do not include this column (just as it ignores the "notes" column).

However, an alternative to custom columns is an assign that has no submission. The advantage is that the grades for this assignment are exported/imported via the CSV export/import from the gradebook. See https://guides.instructure.com/m/4152/l/406523-how-do-i-create-extra-assignment-columns-for-non-submission-assignments-in-the-gradebook

An example of adding an assignment "no submission" is show below. The cursor is below the custom column, while the no submission assignment PROJ1 is shown to the right of Total, with a grade of "B". Note also the notes column is show to the left of the custom column. One can drag the assignment columns around, as one can also do with the Total column; but one cannot move (at least by dragging) the PROJ1 custom column outside of the left hand set of columns. Although one can drag notes and the PROJ1 column back and forth in the left set of columns.
