App Use Case Scenario

In Lesson 18 we covered and app feature where system administrator users are notified regarding consecutive failures of SMS messages and scheduled results. In this lesson we will expand on this by providing a view that can be inspected to find details of failed SMS messages and scheduled functions. This can then be used by users to diagnose the cause and solve the underlying issues.

 

 

Built-In Object Details

In Lesson 18 we briefly mentioned the __sms_result___ and __scheduled_function_result__ builtin-in objects provided by Helium. See below the details of theses objects:

@NotTracked
persistent object __sms_result__ {
    datetime datetimestampStarted;
    datetime datetimestampFinished;
    string destination;   
    int attempt;
    bool success;
    string error;
    bool doneProcessing;
    uuid smsOutboundConfigurationVersionId;
    string smsOutboundConfigurationName;
    uuid smsId;
}
@NotTracked
persistent object __scheduled_function_result__ {
    datetime datetimestampStarted;
    datetime datetimestampFinished;
    string qualifiedName;
    string schedule;
    string error;
    string stackTrace;
    bool success;
}

 

 

 

Data Table Using Built-In Object

Built-in objects do not need to be included in the data model of a Helium app as they are automatically included by Helium. They are read-only and can be accessed like any other object using selectors.

See below for code snippets for the collection source for data tables showing details for SMS and scheduled function results.

 __sms_result__[] getSmsResults() {
	return __sms_result__:all();
}
__scheduled_function_result__[] getScheduledFunctionResults() {
	return __scheduled_function_result__:all();
}

Please consult the source code accompanying this lesson for the full example.
