推荐答案

我不知道你是否需要scope.apply。
这似乎为我工作：

I dont know if you need the scope.apply. This seemed to work for me:

getCrashDetails:function($scope, crashId){
    var deferred = $q.defer();          
    // Get user details if any
    App.CrashInfoTable.all().list(null, function(results) { 
        deferred.resolve(results);
    });
    return deferred.promise;
}
