This is part of a larger effort to split packages out into independent,
composable, PyPI installable Python packages.
While this package itself isn't monumental, it represents the bottom of
the dependecy tree and can be split out before any other packages.
* Minimum possible changes were made to merge CapaModule & CapaDescriptor into
one ProblemBlock class.
* There are no known changes in behavior.
* CapaModule and CapaDescriptor inherited from a number of classes which inherit
from XModule or XModuleDescriptor but did not depend on them. For all these
classes the methods were moved to mixins which did not inherit from either and
then these mixins were added to ProblemBlock in the order which maintains MRO.
The Randomized Content Block XBlock only randomizes the selection of
the children blocks and has unpredictable randomization of
the order of the selected child blocks due to the usage of sets, which
are unordered, for storing the selected blocks. This becomes apparent
when all the available child blocks in a library are chosen for a
Randomized Content Block, to randomize just the order of the child
blocks and not just the selection of the blocks. The order of the
selected blocks ends up being similar for multiple learners.
This change modifies the XBlock to store the selected child blocks in
a list, instead of a set, after randomly shuffling them.
In Studio: Introduces a new option, `after some number of attempts`
and a new entry box for specifying the number of attempts.
This allows course creators to specify that a given question's
answer is only viewable, i.e its show answer button is visible,
after the learner has attempted answering the question -
by hitting the submit button - a given number of times. Included
in this commit are unit tests for the new feature.
This PR is based on #19284 and is part of the
series of work related to the proposal #18134.
This PR avoids the assignment of
anonymous/unenrolled users to any cohort when
course is public. Anonymous or unenrolled users
will only see content that does not have a
content group assigned.
The "View Course" link to the course outline
is shown on the course about page for a course
marked public/public outline.
It also makes course handouts available for
public courses (not for public_outline).
This PR also hides the different warnings and
messages asking the user to sign-in and enroll
in the course, when the course is marked public.
It modifies the default public_view text to
include the component display_name when
unenrolled access is not available.
