[web2py] Re: AppConfig and Storage
Two more questions:
It would seem "take" is preferred since there's some sort of performance
caching? Is there any reason to do "get"?
Can appconfig params be strings with interpolation?
Ex:
[url]
local_server = http://127.0.0.1/%s/details
And then in code:
requests.get(myconf.take('local_server' % '123'))

It would be easy to automate this with fabfile ... set the ENV stuff from
the fabfile according to the machine role, or have 2 "source" ini files,

[web2py] Re: AppConfig and Storage
appconfig is the tool, you are the brain. Everyone has its own
preferences.
Personally I use a post-deployment step to fiddle with settings, as
DEPLOYment is not DEVELOPment.
You can use a SINGLE env variable to switch configs
prod_conf = os.environ('isthisprod')
if prod_conf:
myconf = AppConfig(prod_conf)
else:
myconf = AppConfig(another_path, reload=True)
and I don't see any issues with it. AppConfig is built for speed. There's
absolutely no logic in it.
If you want to concoct your own module for the "merge-inheritance" issue,
code your own.
AppConfig is less than 100 LOC.
BTW: use .take() for production. get() is just a waste of cpu, useful only
for development.

that's how ini parsers work: they parse the value as strings. you can force a conversion of the type using a cast function passed to the take() function.

[web2py] Re: AppConfig and Storage
Once again: it's just an ini parser that works as a singleton when you don't pass reload: it's not black magic.. but it's not made to hold every bit of python syntax (if you want it, you don't need appconfig, just use models and modules.) You calling it not stable is just calling SafeConfigParser() https://docs.python.org/2/library/configparser.html not stable, which I really don't think it's the case. -- Resources: - http://web2py.com - http://web2py.com/book (Documentation) - http://github.com/web2py/web2py (Source code) - https://code.google.com/p/web2py/issues/list (Report Issues) --- You received this message because you are subscribed to the Google Groups web2py-users group.

[web2py] Re: AppConfig and Storage
Beware: since it's made for speed, once you take out the reload on the
initialization, values will be stored indefinitely as they are fetched the
first time.
agreed, already tested it. imho, i think is still not stable.
e.g.
private/appconfig.ini
[auth]
actions_disabled = ['profile', 'register']
[google_analytics_id]
;google_analytics_id = 1
google_analytics_id = None
[meta]
menu = [
(T('Master'), False, URL('master', 'index'), []),
]
1. the auth using list is work fine define it on appconfig.ini
2. the google analytics can work too, when i change the value (None into 1)
3. the meta is crashed because i made it in python style, so when i cut it
on the appconfig.ini n paste in menu.py the error is still occured.
(fetched indefintely)
what i think is not stable, is when i change the value of google analytics,
it just take a few refresh in view page source on browser (the value
change). when i cut the meta menu, paste it on menu.py and do a lot of
refresh, the error is still there.
best regards,
stifan

[web2py] Re: AppConfig and Storage
if you look at the source code, you'll see that it's just an ini parser by default. All that it does is speedup the settings part without users knowing anything about python (think when you finish an app and you deploy it on a system you may not have access to, or if you ship an app to your users) migrate = 1 or True in this case doesn't make a difference, since it's not fetched. However, the migrate implementation takes a truey/falsey value and doesn't do strict type checking, so casting it to int would make it work fine. In case you'd like to pass your own cast function you can. Beware: since it's made for speed, once you take out the reload on the initialization, values will be stored indefinitely as they are fetched the first time.
