In order to reduce friction and ease the rating process for attendees,
we do not force the constraint stating that the message must contain a
message or an attachment onto the users. Instead, we allow ratings and
replace the empty message by a blank space to avoid triggering the error
message. If no stars are selected, an error message is now displayed to
the user, asking to select a rating before submission, preventing them
to post their review until then.
Since we do not really support 0 stars ratings, and do not want the user
to see that error message in case of the course, we set the default rating
to 4.0 instead of 0.0.
-> Therefore, we also remove the grey star contrast coloring on first review
since we do not want the user to have the impression a choice has already
be made beforehand. In that case, everything will be yellow.
Void content detection is done by extracting it in both python (portal
chatter post controller) and frontend (submission check) and relaxing it
in slides modules.
