Unsubscribing an observer while running create, update or delete operations on modal in Laravel

Today I was trying to copy some data from one application to another application. The Data has some nested relationships so I created a custom feature to fetch the data using Apis and insert them one by one into my destination application.

My problem while inserting the data was, there was an observer is set to File.php (for example) model that was running run logic to upload the incoming file to AWS s3 Cloude storage. But I am not really uploading anything while inserting the data. So, I want to stop the Observer from running the functionality while I was running my custom feature.

While looking for some solution to my problem I came to a solution that I would like to share with you.

File::unsetEventDispatcher();

I used this function call before running the logic only once and my observer stopped executing the code on Create and Update model event.

You can also use the same code to stop the other event from executing while running some logic.

You can get all the event displachers and filter the displachers you want to dispatch while running your logic.

$dispatcher = YourModel::getEventDispatcher();

Then you can update the $displacher array and set the Event displachers again:

YourModel::setEventDispatcher($dispatcher);

I hope this will help you to solve the problem and give you some new thoughts about playing with events.

Get Google Calender's Event Notifications Or Reminder Notifications On Windows

Hi Friends, I was struggling for some days to get better notifications for google calender's events or reminders that I have set for myself but I was able to only get the browser notifications that was not quite working for me.
