The Example Extension

Our first extension will show an inventory list of products, which we created in a backend list module. Each product consists of a title, a short description and the number of pieces in stock. The following steps are necessary for implementation:

1. Create directory tree and the minimal configuration files
2. Translate the problem domain to an abstract domain model
3. Configuration of the persistence layer
   • Define the database tables
   • Configure the display of backend forms
   • Create repositories for product objects
4. Define the application flow inside the extension (create controller and action methods)
5. Implement design with HTML-templates
6. Configure the plugin for list display
7. Install and test the extension
