I'm trying to make a web2py app in which users have to insert a lot of different types of data. Once all the data have been added the user should be able to click on a button to get the app to elaborate the data and produce the final output.
What would be the simplest way to disable the button until all the relevant data have been added, and to activate it automatically once everything is ready? Or would you suggest a different type of approach altogether? Michele
