angularjs - Angular and Breeze fetchMetaData -

i'm curious if there alternatives fetching meta data breeze when using angular. since $q , q promises don't play nice each other decided use q.js promises , not $q. in controller i'm checking if metadatastore empty:

  if (maindataservice.manager.metadatastore.isempty())             {                 $log.info('metadatastore empty') ;                  maindataservice.getmetadata()                   .then(function ()                   {                      enablecreatebutton();                   });             } 

the basic idea if don't have meta data go fetch , enable buttons allow me create new record.

to accomplish define q promise in data service after breeze resolves promise resolve promise.

  function getmetadata() {      var mymetadatapromise = q.defer();      q.delay(0).then(function () {          manager.metadatastore.fetchmetadata(servicename).then(function () {             mymetadatapromise.resolve();         });      });     return mymetadatapromise.promise;    } 

any suggestions make cleaner great. 1 thought had define promise in controller , have data service return breeze promise. thought clutter controller , not separate out concerns.

take @ new to$q extension in breeze labs on github have been using pretty extensively effect.

we haven't documented yet comments explain how "install" , use it.

your maindataservice.getmetadata() be:

 return manager.metadatastore.fetchmetadata(servicename).to$q(); 

and subsequently intended:

 maindataservice.getmetadata()     .then(function() { enablecreatebutton(); }); 

you in land of $q. angular $apply enablecreatebutton automatically.
