Payum Symfony Doctrine Can't Create Table - php

Question

I am trying to add a reference to a profile (called Square) to my Payment model (extension of Payum\Core\Model\ArrayObject), but I can't add a foreign key on the table. I want to do this so that when the payment is processed I can update a field saying that the square is now paid. Here is my setup:
Square.php
/**
* #var integer
*
* #ORM\Column(name="msid", type="integer")
* #ORM\Id
* #ORM\GeneratedValue(strategy="IDENTITY")
*/
private $msid;
Payment.php
/**
* #ORM\OneToOne(targetEntity="Square")
* #ORM\JoinColumn(name="msid", referencedColumnName="msid")
*/
private $square;
Error Codes:
[Doctrine\DBAL\Exception\DriverException]
An exception occurred while executing 'ALTER TABLE payment ADD CONSTRAINT FK_6D28840D405F5364 FOREIGN KEY (msid) REFERENCES square (msid)':
SQLSTATE[HY000]: General error: 1005 Can't create table 'memorysq_version2.#sql-1658_1487b' (errno: 150)
Several other entities use the msid field to join on, it just isn't working with my Payum Payment model.

Answer 1

The error message actually says that MySQL can't create the foreign key. Since you're executing an ALTER TABLE, the tables should already be there. Since the tables presumably already exist, it could be that there's already some data in the payment table, which isn't in the square table.
Other stuff worth looking into is if both columns have the exact same type (including signed/unsigned) and have a matching collation. On the table level, you could look at if the engine is the same, if the charset is the same and if both tables aren't temporary tables.
