I just discovered this great tool : ModelBaker.
From the GUI you can quickly draws your models, relationships, validation rules…
Then just click on the “Build and Go” button and it will automatically generates the database tables with random data and a CakePHP CRUD with CSS themes…
Just point and click and it will do the rest !
Very nice tool thanks to Jonathan Freeman / Widget Press
Download ModelBaker from widgetpress.com
It can even generates an Iphone version on the fly !
