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.
When an unknown content type is encountered, it's imported as a
RawDescriptor, which will preserve the OLX and export it back out. But
if we import a course while an XBlock is installed and then export it
after that XBlock is removed, we export RawDescriptors that never got to
save the original OLX and have a blank "data" field. Attempting to
export this used to fail and break export altogether. We now test that
the export continues to complete, and just skips over anything it can't
serialize out.
Note that this will stil export pointers in the export, so if you
uninstalled a "AmazingBlock" and exported, you might see something like
the following in a vertical's XML::
<vertical display_name="Unit">
<amazing url_name="2edebb68d5734395a06b8a62b9bb677e"/>
</vertical>
However there would be no corresponding file at:
/amazing/2edebb68d5734395a06b8a62b9bb677e.xml
In fact, there would be no /amazing directory at all in the export.
The better long term solution is probably to leave the pointer as-is
and export some generic file that can't be mistaken for OLX (say a
JSON file) that represents the raw key-value data we have in
Modulstore for the now unknown XBlock type. However, this commit at
least keeps export from crashing out entirely.
All code in this PR should be removed after REVE-52 is merged and mobile
traffic from older app versions falls to < 5% of the mobile traffic
to the course_blocks api

Adds VideoModule.public_view() to enable
unenrolled and anonymous users to view the video
contents of a public course.
When an unenrolled or anonymous user accesses the
video content of a public course, the
public_view() introduced in the previous PR is
used instead of student_view() method.
The course_visiblity field can have one of three values:
1. private (default): This keeps the standard access rules.
2. public_outline: Allows unenrolled and anonymous users access to the outline.
3. public: Allows unenrolled and anonymous users access to both outline and
course content.
When an unenrolled user accesses course content, instead of student_view(),
public_view() is used. A default implementation is provided for XBlocks
which do not implement this view. The public_view() must not have any
functionality which assumes the presence of a valid User and should show
a readonly only interface for the XBlock content.
