Here is the same example in YAML format. You can read more about YAML in the YAML
Schema Files (page 195) chapter:
---
# schema.yml
# ...
Address:
columns:
user_id: integer
address: string(255)
country: string(255)
city: string(255)
state: string(2)
postal_code: string(25)
relations:
User:
local: user_id
foreign: id
onDelete: CASCADE
The onDelete option is translated to proper DDL/DML statements when Doctrine creates
your tables.
Note that 'onDelete' => 'CASCADE' is specified on the Address class, since the
Address owns the foreign key (user_id) and database-level cascades are applied on the
foreign key.
Currently, the only two supported database-level cascade styles are for onDelete and
onUpdate. Both are specified on the side that owns the foreign key and applied to your
database schema when Doctrine creates your tables.
