Can be the case, when this is practice, not graded problem. So student will submit answer, and LTI Provider will return 0.3. But self.graded is False, so 0 * 0.3 will be saved. And this is wrong. I will think how to fix that.

This doesn't look like the right way to do this. has_score is a class attribute that is never modified. Is it correct to make it a field in this module that shadows the class attribute? @cpennington ?

Note, that class attribute is removed.

Yeah, we talked about this this morning. has_score is never accessed as a class attribute, and it covers exactly the use-case that @auraz was concerned about (distinguishing between non-scored and scored LTI modules), in a way that 'graded' doesn't.

This PR adds fix for LTI's
max_scoremethod.When LTI module is not graded (attribute
graded=False) methodmax_scorereturns value ofweightattribute, that is1.0by default.It should not be so, because it affects on total score (each additional module adds +1 to the total max score).
@nedbat review, please.
