Single event for single day in fullcalendar month view
I am using the fullCalendar library to add events. The default view is month and I'm loading data from database . Also, whatever the user selects is stored in the database. I have two problems here. Firstly, when the page loads, the library is adding two rows for the same event on the same day. Secondly, I want to limit the user to add a single event for one day. Hence, no day will have multiple events. I have used the following code to load the data and also the click event is present. 
$('#calendar').fullCalendar({
header: {
left : 'prev,next',
center : 'title',
},
defaultView: 'month',
defaultDate: today,
selectable: true,
navLinks: true, // can click day/week names to navigate views
selectHelper: true,/*Load all the events from the database on page load*/
events: {
//Don't have to make an ajax call because full calendar will make the call
//Error and success functions are available.
//On success we will populate the data which is the temp's Availability.
url: loadDataUrl,
error: function(error) {
console.log("error == "+JSON.stringify(error));
},
success: function(data){
var title = 'Availability';
var eventData;
for(var j=0;j<data.length;j++)
{
// $('#calendar').fullCalendar( 'removeEvent', data[j]._id);
var startDate = data[j].date;
if (title) {
eventData = {
title: title,
start: startDate
};
$('#calendar').fullCalendar('renderEvent', eventData, true); // stick? = true
}
$('#calendar').fullCalendar('unselect');
}
}
}, select: function(start, end,jsEvent,view) {
var check = moment(start, 'DD.MM.YYYY').format('YYYY-MM-DD');
var today = moment(new Date(), 'DD.MM.YYYY').format('YYYY-MM-DD');
if(check < today)
{
// Previous Day. show message if you want otherwise do nothing.
// So it will be unselectable
alert("cant select previous dates!");
$('#calendar').fullCalendar('unselect');
}
else
{
var title = 'Availability';
var eventData;
if (title) {
eventData = {
title: title,
start: start
};
$('#calendar').fullCalendar('renderEvent', eventData, true); // stick? = true
sendData(start);
}
$('#calendar').fullCalendar('unselect');
}
} });
Kindly help me out with this issue as i am not able to figure out where I am going wrong. If you check the picture, there are two rows that are created. But I have no clue how that is happening. Also, this happens only when I am trying to load dynamic data. It works fine with static data.
this is the JSFiddle link

Okay I finally got the answer to my question. I had to call the fullCalendar function in the success function of ajax . I've mentioned this below :
var eventArr = [];
var eventData1 ;
$.ajax({
url: loadDataUrl,
datatype: 'json',
type: 'GET',
success: function(data)
{
eventArr = data;
eventData1 = eventArr;
console.log("event data == == "+eventData1);
//Full calendar library.
$('#calendar').fullCalendar({
header: {
left : 'prev,next',
center : 'title',
},
defaultView: 'month',
defaultDate: today,
selectable: true,
selectOverlap : false,
navLinks: true, // can click day/week names to navigate views
selectHelper: true,
events: eventData1, //This will load the events
select: function(start, end,jsEvent,view) {
console.log("View == = = ="+view);
var check = moment(start, 'DD.MM.YYYY').format('YYYY-MM-DD');
var today = moment(new Date(), 'DD.MM.YYYY').format('YYYY-MM-DD');
alert('Current view: ' + view.name);
if(check < today)
{
// Previous Day. show message if you want otherwise do nothing.
// So it will be unselectable
alert("cant select previous dates!");
$('#calendar').fullCalendar('unselect');
}
else {
var title = 'Availability';
var eventData;
if (title) {
eventData = {
title: title,
start: start
};
$('#calendar').fullCalendar('renderEvent', eventData, true); // stick? = true
sendData(start);
}
$('#calendar').fullCalendar('unselect');
}
},
eventClick: function(calEvent, jsEvent, view) {
/**
* calEvent is the event object, so you can access it's properties
*/
if(confirm("Are you sure you want to delete the event " + calEvent.title + " ?")) {
// deleteTempAvailability(calEvent.start._d,calEvent.end._d);
deleteTempAvailability(calEvent.start._d);
// delete in frontend
$('#calendar').fullCalendar('removeEvents', calEvent._id);
}
},
editable: false,
eventLimit: true, // allow "more" link when too many events
});
},
failure: function(err)
{
alert("error == "+err);
}
});
And to ensure that the user can add only a single event per day. All I did was set the selectOverlap to false .
