How to pass multiple pandas Time Series (created in Django view) to Dash callback? about django-plotly-dash

[delsim]

@GarderesG this is not an uncommon issue - in general passing the name (or some other label/tag) of the data to the Dash app through the template, and then using standard Django functionality to access the data inside the callback, is a common use case IMHO.

This means that the real question is what is the best way of making that data available. This depends a lot on your application but in general putting something into a cache using other Django views (eg the one with the template in is usually good; refreshing the app page then repopulates the cache) or mechanism (eg a timer with celery) seems to work well.

You probably don't want to do too much work during a callback, but at the same time if the data is relatively cheap you could have the 'get from cache or repopulate it' logic inside the callback if external population is a step too far.

Thank you for your reply @delsim.
Could you point me in the right direction to implement the 'get from cache or repopulate it' logic? I do not have a huge experience with Django, and I have had trouble finding relevant information about it. Would love to get more details :)
