Hi, i'm trying to block an event by the duration, but it appears the duration isn't calculated until after the event save.
in calendar 5.5.3 i have:
beforeEventSave({eventRecord}){
console.log(`beforeEventSave : ${eventRecord.duration}`);
console.log(eventRecord.data);
// prevent if longer than allowed
if (eventRecord.duration > thisExp[0].data.max_study_length){
Toast.show({html : `duration ${eventRecord.duration} minutes is longer than allowed for experiument ${thisExp[0].data.max_study_length}`})
return false;
}
}
//.max_study_length is 240
In the attached you can see the .duration is just the default 60 mins duration and the calculation is only valid after saving for a second time
Should i be calculating myself, or grabbing duration from elsewhere?
Calendar shares its data layer with Scheduler, and Scheduler in turn uses an async scheduling engine (which for the basic Scheduler & Calendar only normalizes dates & durations). This means that when changing a time component of an event, the related fields are updated "later". For example if you change the duration:
// Initial data for event
{
startDate : '2023-11-10',
duration : 1,
endDate : '2023-11-11'
}
event.duration = 2;
// Here event.endDate has not yet been calculated
To be sure that calculations (scheduling) has finished, you can use:
event.duration = 2;
await calendar.project.commitAsync();
// Here event.endDate has been recalculated
thanks. i ended up just monitoring the change of the endTime and calculating my own duration
//the end time selector
endTimeField : {
//fixed to 15m increments
picker : {
items : {
minute : { step : 15 }
}
},
//save the endDate with updated time
//have to copy the date from start because times are generic until after the sync
listeners : {
change(event){
console.log(`change end time event:`);
//clone the start date
var tmpTime = new Date(currStartDate);
//set the end time
currEndDate = DateHelper.copyTimeValues(tmpTime,event.value);
console.log(currEndDate);
//save duration
currDuration = DateHelper.diff(currStartDate, currEndDate, 'minute');
}
}
},
