Support - Assistance technique

Hi,

I am enrolling a child with certain attributes like First Name, Last Name, Phone Number and saving it on the server using the Android SDK.

How can I retrieve that enrollment based on the Phone Number value?

Thanks,

Hi Apoorv,

Here is an example of web API calls and SDK method references which will search TrackedEntityInstances based on attribute values.

Demo server credentials:

  • username: android

  • password: Android123

First, you need to find TrackedEntityInstance (child) on server by filtering on corresponding attributes (phone number or first name in this example).

Example of API request: https://play.dhis2.org/demo/api/trackedEntityInstances.json?ou=DiszpKrYNg8&program=IpHINAT79UW&filter=w75KJ2mc4zz:LIKE:donald

In SDK, you can use TrackerController.queryTrackedEntityInstancesDataFromServer() method which allows you to search TrackedEntityInstances based on attribute values.

Method in SDK: https://github.com/dhis2/dhis2-android-sdk/blob/2.22-legacy/core/src/main/java/org/hisp/dhis/android/sdk/controllers/tracker/TrackerController.java#L402

Second, you need to get enrollments which are assigned to given TrackedEntityInstance.

Example of API request: https://play.dhis2.org/demo/api/enrollments.json?ou=DiszpKrYNg8&program=IpHINAT79UW&trackedEntityInstance=XF7tJoenIpr

This call will download and save specified TrackedEntityInstances with assigned Enrollments:

Method in SDK: https://github.com/dhis2/dhis2-android-sdk/blob/2.22-legacy/core/src/main/java/org/hisp/dhis/android/sdk/controllers/tracker/TrackerController.java#L410

Best regards,
