I'm not 100% sure what you're trying to do here, but I have some
observations. Maybe they're useful, maybe not.
1) $scope.jvcModels isn't an array, but a promise. You need to do something
like
myDataService.FetchJVCModels().then(function(data){$scope.jvcModels=data;
/* do what you will with jvcModels here*/});, more or less.
2) You're doing an unnecessary $q.all call - $q.all returns a promise for
an array when given an array of promises, but $http.post is just a single
item. At best that's weird, at worst it won't work. Never tried it myself.
If you must, i'd do $q.all([$http...])
3) You don't have a .catch call at the end of your promise chain, so errors
from $http will just evaporate. I'd suggest returning
promise.catch(function(err){console.log('ERRORRR!');}) instead of just the
promise. It will still be a promise that will still resolve to the data,
but you'll also catch errors. That said, I usually don't put a .catch in
service fetch calls, but rather manually attach them to the end of all my
promise chains.
