#### Foreign keys
Since 2.0.8 the generator supports foreign keys using the `foreignKey` keyword.

'id' => $this->primaryKey(),
'author_id' => $this->integer()->notNull(),
'category_id' => $this->integer()->defaultValue(1),
'title' => $this->string(),
'body' => $this->text(),
]);

$this->createIndex(
'idx-post-author_id',

'author_id',

// creates index for column `category_id`
$this->createIndex(
'idx-post-category_id',
'post',
'category_id'
);
// add foreign key for table `category`
$this->addForeignKey(
'fk-post-category_id',
'post',
'category_id',
'category',
'id',
'CASCADE'
);
}
/**

public function down()
{

$this->dropForeignKey(
'fk-post-author_id',
'post'
);
// drops index for column `author_id`
$this->dropIndex(
'idx-post-author_id',

);
// drops foreign key for table `category`
$this->dropForeignKey(
'fk-post-category_id',
'post'
);
// drops index for column `category_id`
$this->dropIndex(
'idx-post-category_id',
'post'
);
$this->dropTable('post');
}
}
```
The position of the `foreignKey` keyword in the column description doesn't
change the generated code. That means:
- `author_id:integer:notNull:foreignKey(user)`
- `author_id:integer:foreignKey(user):notNull`
- `author_id:foreignKey(user):integer:notNull`
All generate the same code.
The `foreignKey` keyword can take a parameter between parenthesis which will be
the name of the related table for the generated foreign key. If no parameter
is passed then the table name will be deduced from the column name.
In the
example above `author_id:integer:notNull:foreignKey(user)` will generate a
column named `author_id` with a foreign key to the `user` table while
`category_id:integer:default(1):foreignKey` will generate a column `category_id`
with a foreign key to the `category` table.
