Serializing CanvasObjects back to json

[Florian-Kranz]

Hi there and fist of all thanks for this awesome package!

The CanvasObjects work great for the administrative/functional needs like adding users or enrolling them into courses and all that nice stuff. As I am working on a project where i basically proxy the canvas api, a nice feature would be to "deconstruct" the objects back into json.

Right now i am using a slightly modified CanvasObjects.repr function to return valid json, but this gets more complicated with nested json objects (e.g. course_progress in a course object).

What do you think of the idea to add a to_json() function or something like that to the CanvasObject?

Actually converting the object to a dict would be sufficient as they are easily convertible to json. Also it would be less specific to json, the dict could be serialized into a number of data-interchange formats.

This is working for me so far:

    attr_dict = {}
    for attr, value in canvas_object.__dict__.items():
        if attr != 'attributes' and attr != '_requester':
            attr_dict[attr] = value
