Step III¶
Evaluate, Learner Licence 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?,
writtenTestPassed:Boolean = `false`)
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
}
task Evaluate {
input(first!,^second!,result!)
output(writtenTestPassed)
realizer auto
}
task IssueLL {
input(firstName)
realizer auto
}
net DL {
init-document(applicantId, firstName,lastName, age) having coorelation-id (applicantId)
START out (ReviewApplication)
connector C1 in(ReviewApplication) out select {
case applicationFine => `reviewOkay` => SelectQuestion
case default => IssueRegretLetter
}
connector C2 in(SelectQuestion) out(WriteTest)
connector C3 in(WriteTest) out(Evaluate)
connector C4 in(Evaluate) out select {
case writtenTestPassed => `writtenTestPassed` => IssueLL
case default => IssueRegretLetter
}
END in any (IssueRegretLetter,IssueLL)
}
}
- Two task got added here one is Evaluate which checks if answer entered in WriteTest is correct, other is IssueLL which issues a leraner licence. Connector C2 checks if evaluation is fine then Learner Licence gets issued else Regret Letter task gets fired.
- Two new tasks are auto tasks, so we need to provide the code
- EvaluateTaskCode evaluate the written test questionand returns writtenTestPassed as output
- Edit EvaluateTaskCode and replace execute method with the following
def execute(taskId:Id, input:Input): Output = Output(input.first + input.second == input.result)
- Edit IssueLLTaskCode and replace execute method with the following
def execute(taskId:Id, input:Input): Output = {
println(s"Issue LL to ${input.firstName}")
Output()
}
- $compile
- $run
Execute 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)
- Connector C4 tells if right answer is entered then IssueLL task get executed, if wrong answer then IssueRegretLetter, and flow ends if one of them get triggered
- 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 three.
