I have laravel project with voyager admin panel. Right now I need to see statistics on my admin dashboard for products in stores but only from today. So it needs to show me all products made today, to count it and show it on my dashboard.Let me show my code: Here is my DeltaDimmer.php:

I suppose that this is pretty simple to someone who knows JavaScript, but I just can't figure it out on my own.

I've implemented FullCalendar into my Django application, and what I want is simple Event save on users click(saving events to the database after user's action, after the click release and drawn event).

I can add an event using Django form, and have no problem with that, but I want to save the event on click, as I said before. So the user clicks on the desired time, draw the event 'bubble' and let the click off. So when that event is drawn, it needs to be saved directly to the database or passed to the Django form.

I don't have much experience in JS so please don't mind me.

Thank you in advance.

PS: I repeat, everything works fine, I can add an event, delete it, etc, but only with my form.

Let's start with the zakazi.html (page where all the events are created) :

I suppose that this is a simple task, but I just can't figure it out on my own.

I have a Calendar model, Events model, and CalendarGroups model, and a form, with the Event model.

What I need, is a calendar selection, during the event creation.

So, the User wants to add an event and to select a calendar for that event, and the event will be displayed only on that calendar.

For now, I made two calendars from the admin panel, and I can render those two, and they have different ID's, which I can see from the page source.

But when I try to add an event, and when I choose a calendar with ID = 1 for example, the event gets rendered on both calendars(needs to be rendered only on the calendar with ID=1).

This is my models.py :

Ok, I tried to understand all the posts here, but I couldn't. Some are outdated, some are not similar to my problem.

Don't mind me for asking again.

I have a simple HTML table, with some data in it, and I just need to update the data, when it's changed, without refreshing it.

The object has 'is_locked' field, and what I need to do is, when an object is locked(is_locked=True), a small locker icon shows. I can do all of that but after a manual refresh, which is not good.

So when a user, locks an object, after a redirect(page refreshes), locker icon shows. But I need that in a real-time, so when the two users look at the same table, at the same time, after an object lock(from one user), that icon needs to appear on the other user's browser, without refreshing the page.

I just need that 'extra' content(locker icon) to show up in real-time, when the user locks an object.

Try to ignore the custom names(they're not in English)
