I have a problem with outputting the values of a promise function.
$scope.getTeacher = function(teacherAbr) {
var promise = dataService.getTeacher(teacherAbr);
var testje = promise.then(function(payload) {
return payload;
});
return testje; // outputs an d object, not the direct payload values
};
The output of this controller function is this:
However, when I'm doing testje.$$state
it returns undefined
. How can I output the value
object? I can't output the payload
variable in a new $scope, because this data is dynamic.
Here is a simplified version of this on Plunker.

You should change the way you think about things when you work with asynchronous code. You no longer return values, instead you use Promise or callback patterns to invoke code when data becomes available.
In your case your factory can be:
.factory('dataService', function($http, $log, $q) {
return {
getTeacher: function(teacher) {
// Originally this was a jsonp request ('/teacher/' + teacher)
return $http.get('http://echo.jsontest.com/key/value/one/two').then(function(response) {
return response.data;
}, function() {
$log.error(msg, code);
})
}
};
});
And usage in controller:
dataService.getTeacher('Lanc').then(function(data) {
$scope.teacher = data;
});
Also $http.get
already returns promise, so you don't have to create one more with $q.defer()
.
Here is another effort for combining lessons with teachers.

//in your services file
return {
getTeacher: function (teacher) {
// Originally this was a jsonp request ('/teacher/' + teacher)
return $http.get('http://echo.jsontest.com/key/value/one/two')
})
//change the controller to this
dataService.getTeacher(teacherAbr).then(function(msg){
$scope.getdata=msg.data;
console.log("From server"+msg.data);
});
