Accessing the Currently Enrolled User from JavaScript

You may often want to associate things with the current enrolled user in your app. For this purpose, JourneyApps provides a global user variable that you can access from any view's JavaScript.

For example, let's say we want to associate objects that a user creates in the mobile app with that particular user. If we have a form object that belongs to the user as shown below in our Data Model:

<?xml version="1.0" encoding="UTF-8"?>
<schema>
    <!-- Do not remove this - it is used to store information about your mobile users: -->
    <object name="user" label="User">
        <attribute name="name" label="Name" type="string" spec="text.name"/>
        
        <has_many type="form" name="forms" />

        <display format="{name}" />
    </object>

    <!-- Add object types here: -->
    <object name="form" label="Form">
        <attribute name="date_completed" label="Date Completed" type="date" />
        
        <belongs_to type="user" />

        <display format="{date_completed}" />
    </object>
</schema>

...then we can associate a new form (that we create in the init() function in one of our views) with the current user as follows, making use of the global user object:

// This function is called each time the view is loaded
function init() {
    // initialize any data here that should be available when the view is shown
    view.form = DB.form.create();
    view.form.user(user);
}
