Turnkey session 4: ViewModel validation

From MDrivenWiki

In this session, talking about opting out actions so that only the relevant actions are available for the user. I also show how to place the global actions in sub menus to build a complete menu bar. Further mor,e class Constraints are explained and we look on how they can be used to make user aware of rules that they should obey. The concept of DefaultStringRepresentation of objects is also shown.

To make your experience more comfortable, we set the main tags mentioned in the video to the right bar menu of this mini player. Choose the interesting subtitle on the list and immediately get to the exact theme navigation-itemplace in the video. Now you can pick any topic to be instructed without watching the whole video.
