I didn't understand your approach completely, if I have globals
variables/callables like ${g} and ${h}, why would I need another
wrapper (variable_provider)? With Helpers and Globals I'm covering
all my bases right now. Maybe I misunderstand your point.
What I need to know is, which is the best-place/practice to initialize
a global, or any application wide variable, which value is stored in a
table. The rootcontroller maybe? with a boolean global which I set to
True after initializing so it only happens once? also, What if I
change a value? I need a way to reset those globals programatically.
Don't get me wrong here, maybe I'm used to the way it works on Java.
In Java, I have 'listeners' in which I can write a function called
'setupContext' which loads all my globals any time I want, so if I
change a setting of the application, like 'send_confirmation_email' to
false, and then call 'setupContext' the next time a user registers it
wont send a confirmation email.
