Creating CRUD features with CRUDify

Another interesting feature offered by Lift is the CRUDify trait. Imagine if there was a way to get your mappings and generate all the pages necessary to perform CRUD operations without you having to manually create them one by one. What I am saying is that, given a mapping, your application will automatically have all the pages needed to perform the CRUD operations. Wouldn't it be nice if we had such a feature? Well, it happens that we do have such a feature, as the CRUDify trait does exactly this!

Note

CRUD is an acronym for the four basic functions performed to databases and persistent storage, and it stands for Create, Read, Update, and Destroy.

Getting ready

To demonstrate how the CRUDify trait works, we will use the project we created in the Mapping a table to a Scala class recipe.

You can duplicate it or just modify the same project.

How to do it...

Carry out the following steps:

  1. Mix-in the CRUDify trait in the Contact object as follows:

    object Contact extends...
