Why isnt Scheduler populated with appointments from my Mongodb server (using Mongoose)?

[Youssef Lakdime]

I am building a MEAN-application with Scheduler. Creating appointments and saving them to the mongodb database works flawlessly, hoewever, the schedulers remains empty while there are many appointments in the database. This is in my index.js

app.post("/GetData", (req, res) => {
    Event.find({}, function(err, events) {
            res.send(events);
    });
    });

I see in my Network tab in my browsers developer tools that when the Scheduler is loaded, the 'getData returns a '200 OK' with the request

Running the 'GetData' endpoint in postman gives me these documents:

 {
        "_id": "5dc835d6wefw835250ab4456",
        "startTime": "Tue Nov 12 2019 12:00:00 GMT+0100 (GMT+01:00)",
        "endTime": "Tue Nov 12 2019 12:30:00 GMT+0100 (GMT+01:00)",
        "subject": "Work",
        "klant": "Simon",
        "km": 43,
        "business": true,
        "location": "Amsterdam",
        "description": "test",
        "__v": 0
    }

How does it come that I dont see the appointments in the scheduler?

[Youssef Lakdime]

private dataManager: DataManager = new DataManager({
  url: 'http://localhost:8000/GetData',
  crudUrl: 'http://localhost:8000/BatchData',
  adaptor: new UrlAdaptor
});

this is what I have as dataManager

Hi Youssef, 

 

Syncfusion Greetings. 

 

We have tested your shared code in which field mapping is incorrect, which is the root cause of the reported issue. We prepared the sample below with the right field mapping, please refer to it.

Hello

please can someone help me with the execution of the program gives me this time offset in the frontback part of the project but at the database it saves the exact times

mongoDB

Hi Yasser,

Greetings from Syncfusion support.

We have validated your query based on your shared images and in your DB the appointment start and end times are stored in the UTC format. By default, while assigning this data to the Scheduler it automatically converts the start and end times of the appointment based on the System timezone. Because of that, the Scheduler appointments are rendered in the 11.

Ex: If you are in the UTC +3 Moscow timezone. If the appointment start time is May 19, 2022, at 9 AM in UTC. The Schedule automatically adds three hours to the appointment start time-based on the System's local timezone UTC +3 Moscow. So, the appointment was rendered on May 19, 2022, at 11 AM.

If you want the Schedule to render the appointment at the exact time that is stored in the DB can you kindly share the below details?

• Are you using the Timezone property of the Schedule?
• If yes can you share the Timezone property value?

Refer to the below UG for more details about working with Schedule Timezone.

Hello,

Please, I need help. I want to save in the database "idUser" to have each activity has a user who created.

I managed to create "idUser" in the database as you see.

==> Code "routes/activity"

==> database

Now I want to give the value of "id User", how i pass the value? knowing that I can recover the value and I don't know how to add it ?

==> Code "activity.component.ts"

[Ravikumar Venkatesan]

Hi Yasser,

We have validated your query “I want to save in the database ‘idUser’” at our end. We suggest you add the IdUser field value to the added or changed appointment data on the actionComplete event of the Schedule as shown in the below code snippet. So, you can get the IdUser field value that will be available at the server end and you can store it in your DataBase.

[app.component.ts]

export class AppComponent {

  public data: Record<string, any>[] = extend([], zooEventsData, null, true) as Record<string, any>[];

  public selectedDate: Date = new Date(2021, 1, 15);

  public eventSettings: EventSettingsModel = { dataSource: this.data };

  public currentView: View = 'Week';

 

  public onActionComplete(args: ActionEventArgs): void {

    if (args.requestType === 'eventCreated') {

      // This block will execute once an appointment is created

      args.addedRecords[0].IdUser = 'User Id';

    }

    else if (args.requestType === 'eventChanged') {

      // This block will execute once an appointment is edited

      args.changedRecords[0].IdUser = 'User Id';

    }

  }

}

I followed all the steps you suggested !!

==> Code "activity.component.ts"

==> Code "activity.component.html"

==> Code "routes/activity"

==> database

Did I do something wrong ?

[Ravikumar Venkatesan]

Hi Yasser,

Sorry for the inconvenience caused.

We have validated your query “Did I do something wrong ?” at our end. We suggest you add the IdUser field value to the added or changed appointment data on the actionBegin event of the Schedule as shown in the below code snippet. So, you can get the IdUser field value that will be available at the server end and you can store it in your DataBase.

[app.component.ts]

export class AppComponent {

  public onActionBegin(args: ActionEventArgs): void {

    console.log('args: ', args);

    if (args.requestType === 'eventCreate') {

      // This block will execute once an appointment is created

      args.addedRecords[0].IdUser = 1;

    }

    else if (args.requestType === 'eventChange') {

      // This block will execute once an appointment is edited

      args.changedRecords[0].IdUser = 1;

    }

  }

}

I have another question, Now I want to show up the "activity" by user connected.

I edited in API, I gave him parameter "id_User".

==> Code "routes/activity"

But, I don't know how to add the parameter in here ??

==> Code "activity.component.ts"

[Ravikumar Venkatesan]

Hi Yasser,

We have validated your query “I have another question, Now I want to show up the "activity" by user connected.” at our end. You can achieve your requirement by sending the user id as an additional parameter to the server using the addParams method of the Query. Refer to the below UG for more details.

Hey, i have a question please, i dont know how to use this Scheduler for that when the user connects to my app can only see, add or modify his activities.

And can i add like a userID attribute that links every activity added to the MONGODB database with its own user ??

If you could explain in the best way possible i would really appreciate it.

i am working with the MERN stack if that could help.

[Ravikumar Venkatesan]

Hi MEHDI,

Greetings from Syncfusion support.

Q1: I don't know how to use this Scheduler for that when the user connects to my app can only see, add or modify his activities.

You can send the userID to the server end using the addParams method. So, you can filter the userID specified activities alone from the server end and you can return them to the client end. So, the user can only see and edit the activities connected with his userID. Refer to the below update.

Q2: Can I add a userID attribute that links every activity added to the MongoDB database with its own user?

You can add the userID field to every activity added to the server using the actionBegin event of the Schedule as we suggested in the below update.
