Troubleshooting: Problems with AngularJS $http.get functionality not functioning as expected

I have a user list that I need to display. Each user has unread messages and has not created a meal list yet. I want to make two http.get requests within the main http.get request to retrieve the necessary information, but I am facing an issue with asynchronous execution, causing the values for unread messages and weeks to not update correctly. How can I resolve this? Thank you in advance.

$http.get('http://example.com/users').success(function(response){         
            var data=response;
            if(data==null || data.length<=0){
                return;
            }
            var date2 = new Date();

            var users=[];

            for(var i=0;i<data.length;i++){
                var diffDays=0;

                if(data[i].uyelikBaslangicTarihi=="0"){                             
                    continue;
                }
                var from = data[i].uyelikBaslangicTarihi.substring(0,10).split("/");                    
                var date1 = new Date(from[2], (from[1] - 1), from[0]);                  
                var timeDiff = Math.abs(date2.getTime() - date1.getTime());
                diffDays = Math.ceil(timeDiff / (1000 * 3600 * 24)); 
                if(diffDays>28 || diffDays<0){                              
                    continue;
                }
                var week=diffDays/7;
                week=parseInt(week);
                if(diffDays/7>0)
                    week++;                     
                if(week!=0)
                    week--;
                var unloadweek=week+1;
                var unreadmessage=0;


                $http.get('http://example.com/menus?userId=' + data[i]._id + '&haftaSayisi=' + week).success(function(response){        
                    if(response==null || response.length==0){unloadweek= "";}
                    else{unloadweek= week;}          
                });
                $http.get('http://example.com/sorus?userId=' + data[i]._id + '&okundu=0').success(function(response){   
                    console.log(response);
                    if(response==null){ unreadmessage= 0;}
                    else{unreadmessage = response.length;}       
                });
                var color="white"       

                var gender='mars'   

                if(data[i].cinsiyet=="Kadın")
                    gender='venus';
                var user={
                    id:data[i]._id,
                    name:data[i].ad,
                    gender:gender,
                    weight:data[i].kilo,
                    height:data[i].boy,
                    birthday:data[i].dogum_tarihi,
                    email:data[i].email,
                    src:"http://example.com/images/"+data[i]._id+".jpeg",
                    color:color,
                    week:unloadweek,
                    unreadmessage:unreadmessage
                }
                if(data[i].uyelikBaslangicTarihi!="" && data[i].uyelikBaslangicTarihi!="0" && data[i].rol!="admin")
                    users.push(user);

            }
            $scope.customers=users;



        })
        .error(function(err){
           alert("hata");
        }

)

Answer №1

Ensure you are properly chaining your http requests and promises. It is important to refer to the documentation for guidance (check below).

Also, be mindful of variable scope within your code - make sure variables like unloadweek are defined in the right context, especially when used within a for loop.

If you suspect issues with your code structure, it may be beneficial to make improvements in that area as well.
