Parent Child Relationship With A Single Entity In Doctrine 2

Question

I have database table that looks like this:

+----+--------+--------------------+
| id | parent | description        |
+----+--------+--------------------+
|  1 |          


        

Answer 1

To do this in YAML, the configuration would look something like:

AppBundle\Entity\Category:
    type: entity
    table: category
    repositoryClass: AppBundle\Repository\CategoryRepository
    id:
        id:
            type: integer
            id: true
            generator:
                strategy: AUTO
    oneToMany:
        children:
            targetEntity: Category
            mappedBy: parent
    manyToOne:
        parent:
            targetEntity: Category
            inversedBy: children
