Session initialisation

In the previous section, we indicated to Ninoxbee the name of a function in our business app that will handle the initialisation of a session for the user. This function needs to be implemented in your business app as it will allow to to track all answers for a specific form submission and attach these answers back to your business app.

In your business application (e.g Training), we will create a new function called initSession()

function getForm(_formId : text) do
	first(select Form where 'Form ID' = _formId)
end;
function getSubmission(_formId : text,_submissionId : text) do
	first(select Session where Form.'Form ID' = _formId and 'Session Id' = _submissionId)
end;
function getOrCreateSubmission(_formId : text,_submissionId : text) do
	let s := getSubmission(_formId, _submissionId);
	if s = null then
		let form := getForm(_formId);
		let newSubmission := (create Session);
		newSubmission.(Form := form);
		newSubmission.('Session Id' := generateRandomSubmissionId());
		record(Session,number(newSubmission))
	else
		record(Session,number(s))
	end
function initSession(_formId : text) do
	"Expected Response";
	let submission := getOrCreateSubmission(_formId, "");
	{
		submissionId: submission.'Session Id'
	}
end;

It's this object that is counted in your monthly plan.

Now that we've created our session, let's move to implement the function that fetches the next question from your business app
