On Rails, Ext JS, Netzke, and nomadic lifestyle
In this tutorial we will build (from scratch) a composite component that will nest 2 grids (linked by a one-to-many relationship) and a form that will display some details about the record that is selected in one of the grids. I will show how easy it is to update all nested components within a single client-server roundtrip, using an approach which gives the developer a great level of freedom in building complex components. Live demo for this tutorial can be found here, while the code can be found in the netzke-demo project (the rails3 branch) on GitHub.
