I'm using Wakanda platform and I am developing a web based application that schedules trips for a non emergency transportation company as a project. I have created datastore classes for some job positions, patients and vehicles. I have created a form for the schedule that contains attributes from extended classes like patient name, driver name and vehicle ID. In order to get those values I have tried to access them from relation attributes and by using calculated attributes within the schedule class but it doesn't work! So what I need is to access the related values from the general class that will output the timetable for each day with values like id, time, date, patient name, address, driver name, assistant name and vehicle ID. The way that I tried to access those values is by using alias attributes and it works as the screenshot shows but alias attributes are not storage attributes. Here is a query that I have posted on stackoverflow forum that may help the situation regarding what I want to achieve! [login to view URL]
