Extend an ExtendType

[michilehr]

Hi,

is it possible extending an ExtendType?

Tried out but did not succeed yet.

Thanks for helping out!

Why would you need to extend a type twice? Can you just create a base class and extends that class, then add the ExtendType annotation to the sub class?

Hi @oojacoboo,

thank you for your fast reply.

We have our Entity User in which we just use the type annotation. Now we have a UserExtendedType which includes all fields we want to expose for separation of concerns (we have logic for example for the image link which should not be located in the entity).

Now we need another type in which we control the behaviour of the last name so it just outputs the initial character for special usage which we want to define by outputType.

Another way would be to have the context of the parent type so we can control the behaviour in the method directly.

Ah you mean put the Type on the ExtendedType which extends the user and make this the default User type so others will extend this type. I will check thanks!

Use more standard PHP class hierarchy and organization and don't rely too heavily on the GraphQL annotations and you'll probably end up with a much better/cleaner design.

Is it then possible that the Type uses the name of the entity so the user is available by the name user so the relationship still works?

class User 
{
    public function getName(): string;
}

#[Type]
class UserOne extends User 
{
    /**
     * Custom name for User
     */
    #[Field]
    public function getName(): string;
}

#[Type]
class UserTwo extends User 
{
    /**
     * Only the initial for the name
     */
    #[Field]
    public function getName(): string;
}

Each of the classes UserOne and UserTwo will result in 2 separate types. If you still need to return a User entity/type or have it accessible through the graph, I think you can still include a Type annotation on it as well.

I totally misunderstood the concept. An ExtendedType extends an existing type and is not a new type by himself.
Thanks @oojacoboo 🙏
