Problem Symfony/Doctrine : One-To-Many - Self-referencing on a primary key

I would like to have a "post" with an identifier. This one could be classified in another "post" by storing the identifier of his parent.
I tried to do like this:
class Post {
/**
* @ORMId
* @ORMGeneratedValue
* @ORMColumn(type="integer")
* @ORMOneToMany(targetEntity="Post", mappedBy="Id_Post_Parent")
*/
private $Id_Post;
/**
* @ORMManyToOne(targetEntity="AppEntityPost", inversedBy="Id_Post")
* @ORMJoinColumn(name="Id_Post", referencedColumnName="Id_Post", nullable=true)
*/
private $Id_Post_Parent;
...
}
but I have this error when i'm checking with doctrine:schema:validate :
[FAIL] The entity-class AppEntityPost mapping is invalid:
- The association AppEntityPost#Id_Post_Parent refers to the inverse side field AppEntityPost#Id_Post which is not defined as association.
- The association AppEntityPost#Id_Post_Parent refers to the inverse side field AppEntityPost#Id_Post which does not exist.
- The referenced column name 'Id_Post' has to be a primary key column on the target entity class 'AppEntityPost'.
Can someone help me to fix this ?

There is small logical error with your structure - your ID_Post variable tries to be both the primary key (the ID) and the collection association side. I didn't check this syntax in too much details (you can find an example of this association along with most of the other associations from doctrine documentation: https://www.doctrine-project.org/projects/doctrine-orm/en/2.6/reference/association-mapping.html#one-to-many-self-referencing), but basically you need to add the children association separately to your entity like this:
class Post
{
/**
* @ORMId
* @ORMGeneratedValue
* @ORMColumn(type="integer")
*/
private $id;
/**
* @ORMManyToOne(targetEntity="Post", inversedBy="postChildren")
* @ORMJoinColumn(name="id_parent_post", referencedColumnName="id", nullable=true)
*/
private $postParent;
/**
* @ORMOneToMany(targetEntity="Post", mappedBy="postParent")
*/
private $postChildren;
public function __construct() {
$this->postChildren = new DoctrineCommonCollectionsArrayCollection();
}
}

Isn't it possible to get a recursive entity on the Id ? Actually I wanted to get the Id of another post into each one
– Azrix
Nov 23 '18 at 21:15
it is referencing to the ID of the parent post entity - that part is visible in the $Post_parent join column definition 'referencedColumnName="Id_Post". I.e. this entity structure will generate in the database columns "Id_Post" (the post id) and "Id_Parent_Post" (the foreign key reference to the parent post id). Assuming that "recursive entity" means "self-referencing entity" that is.

Are you using doctrine to generate the database structure from the entities or have you defined your table separately? Namely, do you have column with name "Post_Id" in the related database table for posts?

ah, I just typoed the field name the wrong away around in my comment there. But that's fine, you answered to the question in any case. I haven't checked how doctrine handles the capitalized member variable names when generating the column names so there might be some mismatch due to that - I updated the example above to use the names without the capitals (if you don't want to regenerate the schema - you can also just check what the actual database column name is for the id: and if it is "id_post" (without capitals), update the "referencedColumnName" to use this uncapitalized version.
