With the release of the AppCloud, Mendix introduced a new project layout and module that make use of the new Mendix AppCloud services. With the AppCloud Default Project layout you can easily create new apps that make use of AppCloud services out of the box. You can upgrade your existing app with the separate AppCloudServices module. Do you want to know more about all the possibilities this opens up? Take a look at the press release.

In this how-to we will explain how you can incorporate the AppCloudServices module into your existing app.

1. Read More

The AppCloudServices module requires version 5.3.2 of the Mendix Modeler. If your app was not created with Mendix 5.3.2 or newer, you need to convert it first. For more information about converting apps, see this page.

2. Step-by-step Guide with an Example

This how-to uses version 3.0 of the Company Expenses (CE) app, which does not yet contain the AppCloudServices module. This version can be found in the Modeler AppStore by going to the app page and opening the versions tab. Company Expenses 3.0 was built in an older version of Mendix, so it should first be converted to Mendix 5.3.2.

  1. Start the Mendix Modeler and open your existing app that has been converted to Mendix 5.3.2 or newer.
  2. Open the App Store inside the Mendix Modeler.
  3. Search for AppCloudServices, click on the AppCloudServices module created by Mendix and click Download.
  4. Select Add as a new module and click on Import. The module should now be visible in the project explorer: Once the module has been imported, you can make use of the Mendix AppCloud Navigation widget. In order to do this, make sure all starting pages in your app use the AppCloudMasterLayout as their master layout. In the CE app, we need to apply the master layout to both UserLoginLayout and DesktopLayoutRightSideBar.

    Do not forget pages which can be opened through microflows and deeplinks.

    If your app does not make use of Mendix 5 layouts yet, you need to convert your app to use Mendix 5 layouts on every page (in Mendix 4, pages were called “forms”). Alternatively, you can manually add the Mendix AppCloud Navigation widget to all pages that are used as starting pages.

  5. Copy and rename the (excluded) microflow Example_OnFirstLoginAppCloudUser (located in the folder Single Sign On/ API) to an appropriate module and include it.

    In the CE app, copying it to the Expenses module and renaming it to OnFirstLoginAppCloudUser is a logical choice.

    Any changes made to the AppCloudServices module in your app will be overwritten when you upgrade to a newer version of the AppCloudServices module.

  6. Open the InvokeOnFirstLoginAppCloudUser microflow from the Single Sign On/Implementation folder. There you will find an action called Call OnFirstLoginAppCloudUser . You need to change this action so it will call the microflow created in the previous step.

  7. Add the boolean attribute **IsLocalUser** (with default **true** ) to your app user entity. This is the entity that represents your user accounts. It extends the System.User entity. The boolean attribute allows you to differentiate between Mendix accounts and local accounts. For the CE app this entity is located in the Expenses module and is called Expenses.Employee. It is a good idea to give the administrator role(s) (or equivalent) read access to the IsLocalUser attribute with an access rule.

  8. Open the microflow you copied in step 5.

  9. Open the Create action and select your app user entity as the object type to be created, instead of the pre-selected UserManagement.Account. You will need to re-set the two attributes in the Create action afterwards.

  10. In the CE app you want to change it to Expenses.Employee, and change the first attribute to FullName and the second to IsLocalUser. Now you want to make sure the StartAppCloudServices microflow is called during startup.

  11. Open the Project Settings.
  12. Go to the Model tab, and set AppCloudServices.StartAppCloudServices as the After startup microflow. Alternatively, you can call this microflow in your own After startup microflow.

    If this microflow is not called during startup, your users will encounter 404 Not Found errors when trying to navigate to your app from the Launchpad.

    Congratulations! Your app now makes use of the AppCloud services.

    When you deploy your upgraded app in the AppCloud it will now be automatically added to your Launchpad. Opening the app from your Launchpad will automatically log you in with your Mendix account, and you can easily invite other Mendix accounts through app user management.
