I suspect this might have already been discussed but didn't find it in any
of the search patterns I tried.
I would like to implement a User class which has basic attributes for aUser
and then a collection if other modules' could add specific user
attributes/methods class(es) which an when used in an application built
from various modules.
class User{
private $user_attributes = new
\Doctrine\Common\Collections\ArrayCollection();
public function addUserAttribute(UserAttributeInterace $attribute){
$this->user_attributes->add($attribute);
}
public function <which extracts a specific Class of
user_attributes>UserAttributeInterace $attribute){
return selected attribute;
}
}
class UserAuthorizationAttributes [implements | extends]
UserAttributeInterface{
private $user_attributes = new
\Doctrine\Common\Collections\ArrayCollection();
}
class UserForumAttributes [implements | extends] UserAttributeInterface{
private $user_attributes = new
\Doctrine\Common\Collections\ArrayCollection();
}
How do I implement this using Doctrine 2 ORM? The options that come to me
are:
1. Implement an abstract class and and persists its contents in it own
table. And then subclass for each application specific user attribute
classes in there own tables. Haven't tried this one yet.
2. Define an interface to help enforce objects added to the
$this->user_attributes. I tried this but schema creation did could not
fine the interface definition so I could not continue to try
3. Have begun looking at Keeping your module
independent<http://docs.doctrine-project.org/projects/doctrine-orm/en/latest/cookbook/resolve-target-entity-listener.html>s
but haven't figured it out enough to see if it would apply
My preference would not to subclass because other namespaces would need to
know about UserAttribute implementation not interface and I would like to
lookup aUser and acquire all the modules' user attributes and not get user
and then have to do a separate lookup for those attributes.
Thanks in advance,
Roy
