Alternative application.conf file (with system property)

Reported by ronin-125131 (at lighthouseapp) | March 10th, 2012 @ 05:58 PM

Hi,

I need a feature like in Play 2.0 to externalize application.conf file.
( see https://github.com/playframework/Play20/wiki/Configuration )

So I tried to implement it. ( I will add a comment with the pull request when I have the ticket number)
It doesn't change anything by default (for compatibility purposes).
But you can force the path to the application.conf by setting a system property.

I hope I did a good job and it will be added to Play! 1.2.X
;-)

Regards,
Neoh

    The pull request is :
    https://github.com/playframework/play/pull/480

    It contains the code and a little upgrade in the documentation to explain it.

    In "samples-and-tests" directory I also add a new application called "external-conf-file" and a file called "external-conf-file.conf"
    You can run the application with "classic mode" : play run => the index page tells you that application file is the internal one.
    Or run with the new feature : play run -Dconfig.file=../external-conf-file.conf => the index page tells you that application file is the external one.

    Feel free to not add this test app if you want.

    I've made some comments on the pullrequest.

    But are this functionality needed? can't you just use the include-functionality and include the file needed?

    I think you can even use groovy code/tag syntax to dynamic resolve what to include.

    I think the include-functionality could be a workaround, but the include functionality was never official, because the magic doesn't work for includes. So I would really appreciate to have this feature, it's more natural and more straight forward.
    Main advantage is for me that the person who run's the software can decided where to put the conf-file. In all other cases the developer decide it.

    It will be very useful for me because my company requires to deploy as war file into JBoss, and let conf file outside of the war. (ex:
    production team can change a parameter, like LDAP server, to swith to a backup environment in case of disaster)

    Still with war file deployment, it can be also useful to switch from a "normal" application.file to a "degraded mode" one.

    And, last but not least, Play! 2.0 offer this feature so it surely be useful. :-)

    PS: I hope my explanations are clear, I'm not fluent with english.

    Ok, I follow you on useful feature.

    But as I said, the pullrequest must also take in account that the python files also load application.conf

    • State changed from “new” to “wontfix”
    • Assigned user set to “Morten Kjetland”

    I think this issue is better solved using a module, for example this one:

    https://github.com/rugbyhead/externalconfig

    I think it is in the process of beeing accepted:
    https://groups.google.com/forum/?fromgroups#!searchin/play-framewor...

    If it cannot load config from filesystem, please ask him to add that functionality
