Office.Cloud.Google.Calendar

About

The Google.Calendar package integrates with the Google Calendar cloud service.

Details

Credits: to Brokero that sponsor the initial implementation of this module.

This is a platform agnostic module that authenticates against Google using the Xpand.XAF.Modules.Google package, for details head to it's wiki page.

The Xpand.XAF.Modules.Office.Cloud.Google.Calendar provides a configurable two way synchronization between the IEvent Domain Components and the Google.Apis.Calendar.v3.Event entity. All CRUD operations will execute the cloud api after a successful XAF transaction.

You can use the model to configure:

The subject Views, the target container Calendar and which Domain Component should be created when a NewCloudEvent.
The CRUD SynchronizationType and the CallDirection.

The package can operate without any configuration by executing a predefined map between the IEvent and Google.Apis.Calendar.v3.Event objects on Update and on Insert for both incoming and outgoing calls.

To customize the predefined map you can use a query like the next one which suffix the Google.Apis.Calendar.v3.Event subject with the current date:

CalendarService.CustomizeSynchronization
    .Do(e => {
        var tuple = e.Instance;
        if (tuple.mapAction != MapAction.Delete){
            if (tuple.callDirection == CallDirection.In){
                tuple.local.Subject = $"{tuple.cloud.Subject} - {DateTime.Now}";
            }
            else if (tuple.callDirection == CallDirection.Out){
                tuple.cloud.Subject = $"{tuple.local.Subject} - {DateTime.Now}";
            }
            e.Handled = true;
        }
    })
    .Subscribe();

Cloud to local synchronization: The package track changes using synchronization tokens.

The first time the run method is called it will perform a full sync and store the sync token. On each subsequent execution it will load the saved sync token and perform an incremental sync.

Possible future improvements:

Any other need you may have.

Let me know if you want me to implement them for you.

Examples

In the next screencast you can see all CRUD operations on the Event BO and how they synchronize with the Google Calendar, for both platforms Win, Web and both directions Incoming, Outgoing. At the bottom the Reactive.Logger.Client.Win is reporting as the module is used.

Issues-Debugging-Troubleshooting

To Step in the source code you need to enable Source Server support in your Visual Studio/Tools/Options/Debugging/Enable Source Server Support. See also How to boost your DevExpress Debugging Experience.

If the package is installed in a way that you do not have access to uninstall it, then you can unload it with the next call at the constructor of your module.
