> 1. Create the model classes
2. Create a test
3. Create the PersistenceObjects
4. Describe the classes
5. Configure DatabaseManager and create the database
6. Use the PersistenceObjects in your controllers
7. Add database-methods
1. Create the model classes
A class should be created for each object that need to be stored in the database. In this example we need three classes:
- User
- Album
- Picture
The following rules need to be remembered here:
- Each class needs an id attribute.
- A setter and getter needs to be created for each attribute that is stored in the database.
- It is required to use camelCase for each classname, property-name and function-name.
class User {
private $userName;
private $id = null;
private $userRole = 0;
private $password = "";
private $albums = array();
private $favouritesAlbum;
public function User() {
$this->favouritesAlbum = new Album();
}
public function getId() {
return $this->id;
}
public function setId($value) {
$this->id = $value;
return $this;
}
....
}
class Album {
private $id = null;
private $name = "";
private $description;
private $pictures = array();
public function Album() {
}
...
}
class Picture {
private $id = null;
private $name;
private $description;
private $url;
private $albums = array();
public function Picture() {
}
...
}
