I might be overthinking it, but if the result_type key is passed, it will return a Quiz object rather than an Assignment. I'm not that type-safe when writing, but this could be a case where someone runs into issues. @Thetwam is it worth adding a test?

[Thetwam]

Good catch. Yeah we'll want to handle that case.

Hi @bennettscience and @Thetwam. Happy to make changes, but I could use a little guidance. I've tested this out on my university's Canvas installation, and I can get two qualitatively different outputs if I pass the result_type="Quiz" kwarg. However, in each case, the duplicated assignment on Canvas is just an ordinary assignment - the only thing that's different are the keywords in the response json that's generated. Similarly, I can pass either of these outputs into an Assignment object or into a Quiz object, with no issues either way. I also get failures when trying to duplicate anything other than a regular assignment (e.g. a quiz or an external tool assignment).

So: what exactly do you want to happen here? Do you want Assignment.duplicate to check the format of the returned json and return a Quiz object in the case where result_type="Quiz", or should it still always return an Assignment object regardless of inputs? In the latter case, maybe I'd need to manually set the is_quiz_assignment attribute?

I'm struggling a bit, as I don't really understand the utility or intent of the result_type functionality in the original API, so any help would be greatly appreciated. Thanks.

@dsavransky Can you see if your instance has the newquizzes_on_quiz_page setting enabled? Re-reading the docs, that setting has to be enabled for the Quiz keyword to serialize it in a Quiz object:

When the root account has the feature ‘newquizzes_on_quiz_page` enabled and this argument is set to “Quiz” the response will be serialized into a quiz format(quizzes);

You shouldn't need to specify the is_quiz_assignment attribute because that's sent from Canvas. Maybe that's a better indicator?

I'm not sure what the intent was on Instructure's side other than to separate out New Quiz functions from Classic.

[dsavransky]

I don't have admin access to the Canvas instance I'm using for testing, so I'm not actually sure how to check that setting (open to suggestions). Here's what I observe: when I omit the result_type keyword, the JSON that's returned includes the is_quiz_assignment key. When I set result_type="Quiz", that key is not in the returned JSON. Instead, it includes: 'quiz_type': 'quizzes.next'.

Good catch. Yeah we'll want to handle that case.
