Question

SchemaTool is generating unique index for associations that are OneToOne. I believe this is incorrect.

Section 6.6 of the Associations manual page at Doctrine shows an example of a OneToOne for a Product has one Shipping. This is shown to generate the Product table:

CREATE TABLE Product (
    id INT AUTO_INCREMENT NOT NULL,
    shipping_id INT DEFAULT NULL,
    PRIMARY KEY(id)
) ENGINE = InnoDB;

However, with the same code for my entity User has one Organisation, my User table SQL is generated as

CREATE TABLE User (
    id INT AUTO_INCREMENT NOT NULL,
    organisation_id INT DEFAULT NULL,
    UNIQ_3B978F9FA7F43455 (organisation_id),
    PRIMARY KEY(id)
) ENGINE = InnoDB;

This prevents me adding 2 users with the same Organisation. Not correct.

I additinally tried to be verbose with the unique JoinColumn annotation param.

@JoinColumn(name="organisation_id", referencedColumnName="id", unique="false")

Any ideas? I can’t seem to find anything at all about this.

Thanks

Answer 1

If One organisation has Many Users and Many Users have One and only one organisation then it’s not a One-to-One association.

One-to-One associations have to be unique.

Your association is ManyToOne on the User side and OneToMany on the organisation side.

User.php

/**
 * @ManyToOne(targetEntity="Organisation")
 */
private $organisation;

Organisation.php

use Doctrine\Common\Collections\ArrayCollection;

/**
 * @OneToMany(targetEntity="User", mappedBy="organisation")
 */
private $users;

function __construct() {
    $this->users = new ArrayCollection();
}
