I want to know how to update my custom app without losing the data related to it .
because when I update json file of my custom app
then using terminal windows with the following command :
bench --site site-name uninstall-app app-name
bench --site site-name install-app app-name
it will delete all the records.It seem a fresh installtion of app.
So can any one tell me. How I can update my whole app without losing the record ?
waiting for the fast response
