ANGULARJS GENERIC FACTORY FOR CONSUMING REST API

Lately,i have been toying around with angularjs,and i have to confess,its quite a powerful framework.My side of the story.

Anyway,after reading much online here is my generic factory for consuming APIs(PHP SLIM 3).

app.factory("Data",['$resource','toaster',
function($resource,toaster)
{
    var serviceBase='http://localhost/bookroom/school.php';//url
    return function(link) //receive part of url with parameters
    {
        return $resource(serviceBase+link,{},{
            query:{method:'GET',isArray:true},//this is for get
            update:{method:'PUT'},
            delete:{method:'DELETE'},
            create:{method:'POST'},
            two_query:{
                      url:serviceBase+link,
                      method:'GET',isArray:false,
                      params:{id:'@id',
                      users_id:'@users_id'
                             }
                      }

     }

            );
    }
}]);


app.controller('usersCtrl',function($scope,$rootScope,$routeParams,$location,$http,Data)
{
    $scope.login={};
    $scope.msgbox={};
    $scope.doLogin=function(users)
    {
      Data('/login').create({users:users},function(response){
           if(response.message=="error")
            {
              //Do something
            }else
            {
               $location.path('dashboard');
            }
         }).$promise;
   }
    $scope.doUserRegister=function(user)
    {
        var user=Data('/input').create({data:user,id:1},function(response){
            $scope.users=response;
            console.log($scope.users);
         }).$promise;
    }});
app.controller('userdisplayCtrl',function($scope,$rootScope,$routeParams,$location,$http,Data)
{

   
         $scope.users={};
        Data('/show/:id').query({id: 1},function(response)
         {
            $scope.users=response;
            console.log($scope.users);
         }).$promise;
}});

  
//This is while sending twoparameters

 Data('/show_2/:id/:users_id').two_query({id: 1,users_id:$routeParams.users_id},function(response){
            $scope.users=response;
            console.log(response.email);
         }).$promise;

});

$app->post('/input', function ($req,$res, $args = []) use($val,$mesg,$help,$get_table)
{
    $id = $req->getParsedBody()['id']; //checks both _GET and _POST [NOT PSR-7 Compliant]
    $data = $req->getParsedBody()['data'];
    $table=get_table($id);
//do something
});

$app->get('/show/{id}',function($req,$res,$args)use($val,$mesg,$get_table)
    {   
            $id=$req->getAttribute('id');
       
            $table=get_table($id);
    //Do something
         });
$app->get('/show_2/{id}/{users_id}',function($req,$res,$args)use($val,$mesg,$get_table)
    {   
        $id=$req->getAttribute('id');
        $users_id=$req->getAttribute('users_id');
        $table=get_table($id);

        //do something

});

function get_table($id="")
{
  if($id==1)
      return "admins";        
  elseif($id==2)
      return "students";
  elseif($id==3)
      return "hostels";
  elseif($id==4)
      return "lecturers";
}
$get_table=get_table();
