Add an event that can be fired when an mform is about to be submitted via ajax.
This allows custom field types to perform an action when the form is submitted.
The atto text editor will reset any autosaves when the form is submitted.
The location is now updated in repeated events if it is altered in one
event and the option 'Also apply changes to the other X events in this
repeat series' is selected. If the location is not altered but some
other details, then manual changes of the location in other events
will not be overriden.
The methods get_module_timestamp_min_limit() and get_module_timestamp_max_limit()
are doing generic stuff and can be used for other calendar event types as well.
I have renamed them to get_timestamp_min_limit() and get_timestamp_max_limit() respectively.
When clicking on an event in the month view, a modal opens with
information about it. That modal did previously only show the start time
of the event. It now also shows the end (if the event has one).
During the calendar work, we have added the feature of
drag and drop activity event or "action events".
The problem at that time was, action events could not be
editable through the calendar UI, but should be allowed
to drag and drop. So, we couldn't use the return of
calendar_edit_event_allowed() because it can return true
(in case of teachers, that have permission to change the
activity) and the attribute isactionevent was created to
control on the UI if the user is viewing an action event.
So what my patch does is just add the check if we are
viewing an action event, and in this case, it won't display
the cog to edit that event.
The requesting user is not always the same as the current user. The container class now allows a different user
to be set as the requesting user. All capability checks are done against the requesting user.
Also, the $requestinguser is passed to core_calendar_provide_event_action and core_calendar_is_event_visible
callback functions. These callback functions need to be updated in all activity modules to accept a $user parameter.
Update get_raw_events_legacy_implementation to work with the passed $users parameter instead of the logged in user.
Also, fixed a bug where get_raw_events_legacy_implementation was failing when $users was set to true, and a list of
$groups was given.
This commit does few tweaks and other performance improvements to
calendar_get_allowed_event_types to be more efficient. Also some minor
queries optimizations on the event form to fetch the list of courses
without groups.
