django события переполнения полного календара не работают

0 голосов
/ 28 апреля 2020

Я пытаюсь реализовать полный календарь в django. Все функции работают нормально, но календарь не обновляется, если я использую refetchevents или rerender events calendar.fullCalendar('refetchEvents');. Если я перезагружаю страницу, события отображаются, но я хочу видеть изменения без перезагрузки страницы. Любая идея, почему это не работает?

Модели: 

from django.db import models

class Events(models.Model):
    id = models.AutoField(primary_key=True)
    name = models.CharField(max_length=255,null=True,blank=True)
    start = models.DateTimeField(null=True,blank=True)
    end = models.DateTimeField(null=True,blank=True)

    def __str__(self):
        return self.name

URL: 

from django.contrib import admin
from django.urls import path
from calend import models
from calend.views import *
from django.conf.urls import url

urlpatterns = [
    path('admin/', admin.site.urls),
    path('', calendar, name='calendar'),
    path('add_event/', add_event, name='add_event'),
    path('update/', update, name='update'),
    path('remove/', remove, name='remove'),
]
