To make your web application more robust, you need to add some validations to the incoming data. You will apply validation rule to your server to verify that all required fields of a model are sent from the client before handling the request. You will decorate the Travel model with attributes that define the required fields, then you will derive from the ActionFilter class and implement the validation of the model. Finally, you will add the validation to the Post action.
The main tasks for this exercise are:
1. Add data annotations to the Traveler class.
2. Create a class that derives from ActionFilterAttribute.
3. Implement the action filter to validate the model.
