loginService.islogged()
Above function return a string like "failed". However, when I try to run then function on it, it will return error of
TypeError: Cannot read property 'then' of undefined
and the cursor is indicate right after connected
and before .then
.
Below is the full function:
var connected=loginService.islogged();
alert(connected);
connected.then(function(msg){
alert("connected value is "+connected);
alert("msg.data value is "+msg.data);
if(!msg.data.account_session || loginService.islogged()=="failed")
$location.path('/login');
});
UPDATE
Here is the islogged()
function
islogged:function(){
var cUid=sessionService.get('uid');
alert("in loginServce, cuid is "+cUid);
var $checkSessionServer=$http.post('data/check_session.php?cUid='+cUid);
$checkSessionServer.then(function(){
alert("session check returned!");
console.log("checkSessionServer is "+$checkSessionServer);
return $checkSessionServer;
});
}
I am certain that the $checkSessionServer
will result in a "failed" string. Nothing more.

You need to return your promise to the calling function.
islogged:function(){
var cUid=sessionService.get('uid');
alert("in loginServce, cuid is "+cUid);
var $checkSessionServer=$http.post('data/check_session.php?cUid='+cUid);
$checkSessionServer.then(function(){
alert("session check returned!");
console.log("checkSessionServer is "+$checkSessionServer);
});
return $checkSessionServer; // <-- return your promise to the calling function
}
TypeError: Cannot read property 'then' of undefined when calling a Django service using AngularJS.
If you are calling a Python service, the code will look like below:
this.updateTalentSupplier=function(supplierObj){
var promise = $http({
method: 'POST',
url: bbConfig.BWS+'updateTalentSupplier/',
data:supplierObj,
withCredentials: false,
contentType:'application/json',
dataType:'json'
});
return promise; //Promise is returned
}
We are using MongoDB as the database(I know it doesn't matter. But if someone is searching with MongoDB + Python (Django) + AngularJS the result should come.
