Update read-only settings

Former Member over 9 years ago

Hi,

I have the following issue noticed: In my datafield I have a read-only setting (version information). When I update the datafield in the Connect IQ store and download the new version to my fenix 3, then the version is not updated in the datafield settings. I need to delete the related settings file in /APPS/SETTINGS/ to get the new value. What is the best practice to deal with read-only settings or is there any parameter to tell the watch, that something is new in the settings?

Kind regards

Moritz

It seems that installing a new version of the app should handle this for you. That said, it does seem that you could hack your way around it with something like this...

// expect a version string resource to be updated for new versions

var currentVersion = Ui.loadResource(Rez.Strings.VersionNumber);



var hasNewSettings = getProperty(currentVersion);

if (hasNewSettings == null) {

  setProperty(currentVersion, 1);



  // must have every setting to migrate in this map

  var propertyCache = {

    "setting1" => null,

    "setting2" => null

  };



  var keys = propertyCache.keys();



  for (var i = 0; i < keys.size(); ++i) {

    var key = keys;



    // copy the value from the old settings file to our cache

    propertyCache[key] = getProperty(key);

  }



  // clear the settings file

  clearProperties();



  for (var i = 0; i < keys.size(); ++i) {

    var key = keys;



    // save the value from the cache to the new settings file

    setProperty(key, propertyCache[key]);

  }

}

[/CODE]

Thank you for the code snippet and idea. I will consider this in the future.
