I want to change the default view of the information of the events of the calendar. At this moment, I need to create a new patient if I want to view the name of him, but I want change this, and allow to view other fields like Comments or Title.
I suppose, you are specifying about the new event/new patient from the calendar. By default, the event category is assumed as the title and shown in the calendar. You need to do minor code modification to show the title.
Also, for the comments, currently it is shown only for the ‘reserved’ category. With minor code modification (accepting all categories), you can show the comments for all the categories.
You need to work with the files in /interface/main/calendar/modules/PostCalendar/pntemplates/default/views/ or or directory for modifying the daily/monthly/weekly calendar and especially ajax_template.html file
