After we added the events, it is time to add a first ViewHelper. Our locations currently has only a name. This is absolutely not enough for a search on GoogleMaps. So the first thing we have to do is extending the model and the add function for the locations.
Since we have more and more actions now and like everybody else we are lazy, we add a navigation now to our layout HTML file. Then we don't have to enter the URL for each action anymore, we can just click the correct link.
