Step II¶
Select Question, Write Test, Issue Regret Letter Tasks¶
- Edit DlProcess.kprocess and change insert the below content to change the DrivingLicense flow
role-ref RTO("rto"), Applicant("applicant")
flow DrivingLicense {
document(applicantId:String, firstName:String,lastName:String, age:Int, reviewOkay:Boolean = `false`,
first:Int?, ^second:Int?, result:Int?)
task ReviewApplication {
input(firstName, lastName, age) display-id("${document.firstName} ${document.lastName}")
output(reviewOkay)
realizer manual(RTO) distribution(system)
}
task SelectQuestion {
output(first!,^second!)
realizer auto
}
task WriteTest {
input(applicantId, first!,^second!) display-id("${document.firstName} ${document.lastName}")
output(result!)
realizer manual(Applicant) distribution(custom)
}
task IssueRegretLetter {
input(firstName)
realizer auto
}
net DL {
init-document(applicantId,firstName,lastName, age)
START out (ReviewApplication)
connector C1 in(ReviewApplication) out select {
case applicationFine => `reviewOkay` => SelectQuestion
case default => IssueRegretLetter
}
connector C2 in(SelectQuestion) out(WriteTest)
END in any(IssueRegretLetter,WriteTest)
}
}
- SelectQuestion,IssueRegretLetter are ‘auto’ tasks, SelectQuestionTaskCode,IssueRegretLetterTaskCode gets generated, need to write code so that they will get executed automatically.
- SelectQuestionTaskCode sets the question with addition of two random number first and second
- Edit SelectQuestionTaskCode in idea, and replace execute method with the following,
def execute(taskId:Id, input:Input): Output = {
import scala.util.Random
Output(first = Random.nextInt(5), second = Random.nextInt(10))
}
- Edit IssueRegretLetterTaskCode in idea, and replace execute method with the following,
def execute(taskId:Id, input:Input): Output = {
println(s"Issue Regret Letter to ${input.firstName}")
Output()
}
- WriteTest task has distribution custom, so we need to let it know how the custom allocation done
- Edit WriteTestTaskAllocationCode and replace allocate method with the following,
def allocate(taskId: Id, input: WriteTestTask.Input): Option[String] = input.applicantId.option
- $compile
- $run
Execute Flow¶
Lets execute Step II task added to the flow
- Go to the browser, and localhost:9000/monitor
- enter username and password rto/rtorto (rto user can create the flow)
- Go to Team tab and click on + button next to the team name
- In Create Flow page select the net DL, application Id as johndoe,and First name as Steve ,Last name as Martin and age as 24.
- Submit will create the flow, and a review Application task (notice the task is allocated to rto)
- Go to localhost:9000/executive to see the task allocated to rto.
- Click on the task display as Steve Martin
- Start the task by clicking on START button, check output Review Okay as true, and COMPLETE
- If you check output Review Okay as false,then as a result of the Connector C1, IssueRegretLetter Task will get executed and End the flow, since the flow ends in any of the task IssueregretLetter or WriteTest.
- Now browse localhost:9000/monitor, notice SelectQuestion auto task got completed automatically, and WriteTest task is assigned to johndoe
- Go to localhost:9000/executive but we need to login as johndoe to complete the task,so logout, and login again in executive as johndoe/johndoe(may use a different browser)
- WriteTest task is listed, start the task. Add the numbers First and Second and enter the Result. Click on Save and Complete.
- Logout and login as rto/rto (If a different browser is used then come back to the previous one)
- Go to http://localhost:9000/report#/flow/search and select Flow Name as DrivingLicence from the dropdown
- Click on search result, and see the details of the flow just got completed along with all the completed tasks.
That concludes the step two which has a flow with auto task and manual task with custom allocation. Also connector is conditional, and flow can end in any of the task completion.
