I'm just beginning to experiment with the Slim framework and RedBean ORM in PHP.
Let's say I have a CommentService registered with Slim's Dependency Injection Container. Also, I have a data model named Comment_Model which is used by RedBean to represent comments stored in a database.
Now, from my route/controller, I want to add a new comment to the database. This is where I'm a bit confused - what would be the "best practice" way of passing information from the route/controller to the service method?
I can think of at least three different ways to do this;
1 - Use an instance of Comment_Model to supply the data:
class CommentService {
public function add(\App\Data\Model\Model_Comment $comment){
// Let the ORM persist the data
}
}
This feels a bit like abusing the data model entity class though - isn't it meant to be instantiated by the ORM, not as a convenience feature to pass around new, unpersisted data?
2 - Separate parameters
class CommentService {
public function add($userId, $message, $replyToId){
// Let the ORM create a proper data model and persist the data
}
}
It works when there are only three parameters, but for something more complex than a comment it could easily get out of hand...
3 - Create a Data Transfer Object
class CommentDTO{
public $userId;
public $message;
public $replyToId;
}
class CommentService {
public function add(\App\Data\DTO\CommentDTO $comment){
// Let the ORM create a proper data model and persist the data
}
}
Isn't it a bit overkill to create a DTO for local use?
Are there any hard rights and wrongs here? What is the "normal" way to do things like this?
