Troubleshooting revIgniter library functions

[Andre Alves Garzia]

Keith,

RevIgniter is a normal LiveCode collection of libraries. Have you read 
the getting started guide at:

   https://revigniter.com/userGuide/overview/getting_started.html

It will walk you through the concepts of MVC and how they are used in 
RevIgniter. Basically your models are the stuff that touch data, views 
are the templates that are shown to the user and controllers are where 
the business logic is. You can also have libraries. So if your DocLogin 
has a function that returns a token, you can call it from a model or a 
controller and get the value.

There is really no "1 minute explanation" that will clear it all, 
RevIgniter is quite easy and consistent but it requires you to go over 
its documentation at least once. Some URLs of interest are:

   https://revigniter.com/userGuide/overview/appflow.html

   https://revigniter.com/userGuide/tutorials/chat.html

I recommend doing the tutorial a lot.

Cheers

andre

The desktop stack includes a single function stack script that logs into the KB server as a proxy ‘public user' and returns an access token string for subsequent page requests.
