How to disable autoplay in iframe. Without using video tag
I need to be able to disable autoplay in an iframe because I want to be able to display the file. And the thing is I don't know what is the file type cause it will be a file the user selected. So like it can be a text file, image, or a video the best I would is the iframe cause I can put any file to be displayed. And that's the reason I don't want to use the video tag cause the file could even be an image or a text file. So I can be able to do that. If it means to be done by JS I wouldn't mind, but NOT JQUERY. And all these files are stored in a Django model so I get the file in a URL or link. So I hope someone could help -

Observing django-background-tasks metrics with Prometheus
I am trying to collect application-specific Prometheus metrics in Django for functions that are called by django-background-tasks. In my application models.py file, I am first adding a custom metric with: my_task_metric = Summary("my_task_metric ", "My task metric") Then, I am adding this to my function to capture the timestamp at which this function was last run successfully: @background() def my_function(): # my function code here # collecting the metric my_task_metric.observe((datetime.now().replace(tzinfo=timezone.utc) - datetime(1970, 1, 1).replace(tzinfo=timezone.utc)).total_seconds()) When I bring up Django, the metric is created and accessible in /metrics. However, after this function is run, the value for sum is 0 as if the metric is not observed. Am I missing something? Or is there a better way to monitor django-background-tasks with Prometheus? -
