Dear All,
I have a 'page' model with a sef-reference:
db.define_table('page',
Field('parent', 'reference page', readable=False, writable=False),
Field('title', unique=True, notnull=True)
//more fields not important here
)
When I insert a new page via appadmin without specifying a 'parent',
everything is OK with sqlite
Since I moved my database to mysql, I have an error :
<class '_mysql_exceptions.IntegrityError'> (1452, 'Cannot add or update a
child row: a foreign key constraint fails (`dommartin25`.`page`, CONSTRAINT
`page_ibfk_1` FOREIGN KEY (`parent`) REFERENCES `page` (`id`) ON DELETE
CASCADE)')
How can I allow null values for the 'parent' field?
Thank you
