Updating one to one doctrine2
For the command-line tool to work a At this point no entity metadata exists in src so you will see a message like "No Metadata Classes to process".Don't worry, we’ll create a Product entity and corresponding metadata in the next section.An entity class must not be final or contain final methods.Additionally it must not implement clone nor wakeup, unless it does so safely. A persistable property is an instance variable of the entity that is saved into and retrieved from the database by Doctrine’s data mapping capabilities. Doctrine 2 is an object-relational mapper (ORM) for PHP 5.4 that provides transparent persistence for PHP objects.It uses the Data Mapper pattern at the heart, aiming for a complete separation of your domain/business logic from the persistence in a relational database management system.The top-level entity definition tag specifies information about the class and table-name.
You can easily recreate the database: The updating of databases uses a Diff Algorithm for a given Database Schema, a cornerstone of the **Doctrine* package, which can even be used without the Doctrine ORM package. Create a Note that all fields are set to protected (not public) with a mutator (getter and setter) defined for every field except $id.
The benefit of Doctrine for the programmer is the ability to focus on the object-oriented business logic and worry about persistence only as a secondary problem.
