AuthCreditErrorRabbitMQ
Employee Time Off System
Sep 2021 - Dec 2021
This application does not use the default user type but is custom. The reason is because there is a team to which the user belongs. This application is divided into two permissions. User permissions allow you to only check requests from your own team. However, administrators can access the all list view. In the case of My Day, since it can be used once a month, the credit is renewed on the 1st of every month. At this time, the scheduled queue is executed using rabbitmq. If the request does not have credit or does not meet other conditions, an error message is returned and displayed on the template to help the user recognize the error and make a proper request.
