HTML5 Caching of Reports in Local Storage

[markiliffe]

A user will not always have a persistent internet connection, therefore the functionality of allowing the user to make reports which would be saved and locally stored would be very useful. HTML5 with javascript allows for this functionality. This script would presumably take the process of;

• Query the internet connection, if connected report normally, if not launch script
• Iterate through the fields contained in the form
• Work out if the required fields are completed, if not inform user.
• Submit form into local storage
• Create flag which, on gaining an internet connection, uploaded local storage to the database.

@dgorissen, you were looking at this at the hackathon. Would you be able to give an overview of what you've done so far and where you'll be going?

I was thinking about a general concept of providing offline functionality and I don't think that form data caching will do the trick on itself. Actually we need to cache the whole application or at least the parts that you want to use offline. My first question is: How does the user load the application without internet connection? Is there anything done already I don't know about?

I created a branch for offline capability: https://github.com/taarifa/Taarifa_Web/blob/offline_capability/taarifa.appcache

It is working right now but it is in a very early stage and there are some issues known: https://github.com/taarifa/Taarifa_Web/issues/45 https://github.com/taarifa/Taarifa_Web/issues/44 https://github.com/taarifa/Taarifa_Web/issues/46

Thanks @nellessen, I think you guys have done sterling service at the hackathon

I'm closing this issue down, as the other issues #44 and #46 have superseded it.
