In the previous chapter we developed the static data module that consisted of emulating the editing of a table from a database. Basically, it was a CRUD of a single table with some extra capabilities. In this chapter, we will learn more about the complexity of managing information from a table. Usually, in real-world applications, the table information that we want to manage has relationships with other tables, and we have to manage these relationships as well. This is what this chapter is all about; how to build screens and manage complex information in Ext JS.
In this chapter we will cover:
Managing complex information with Ext JS
How to handle many-to-many associations
Forms with associations
Reusing components
