I've looked at other people's questions on this topic but can't seem to find where my error is coming from. Any help would be greatly appreciated. I'm including as much as I can think of that might help find the problem:
CREATE TABLE stocks (
id INT AUTO_INCREMENT NOT NULL,
user_id INT(11) UNSIGNED NOT NULL,
ticker VARCHAR(20) NOT NULL,
name VARCHAR(20),
rating INT(11),
position ENUM("strong buy", "buy", "sell", "strong sell", "neutral"),
next_look DATE,
privacy ENUM("public", "private"),
PRIMARY KEY(id),
FOREIGN KEY (user_id) REFERENCES users(id) ON DELETE CASCADE
)
ENGINE=InnoDB DEFAULT CHARSET=utf8;
CREATE TABLE IF NOT EXISTS `stocks_tags` (
`stock_id` INT NOT NULL,
`tag_id` INT NOT NULL,
PRIMARY KEY (`stock_id`,`tag_id`),
KEY `fk_stock_tag` (`tag_id`),
KEY `fk_tag_stock` (`stock_id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
ALTER TABLE `stocks_tags`
ADD CONSTRAINT `fk_stock_tag` FOREIGN KEY (`tag_id`) REFERENCES `tags` (`id`) ON DELETE CASCADE ON UPDATE CASCADE,
ADD CONSTRAINT `fk_tag_stock` FOREIGN KEY (`stock_id`) REFERENCES `stocks` (`id`) ON DELETE CASCADE ON UPDATE CASCADE;
CREATE TABLE tags(
id INT AUTO_INCREMENT NOT NULL PRIMARY KEY,
tags VARCHAR(30),
UNIQUE(tags)
)
ENGINE=INNODB DEFAULT CHARSET=utf8;
And the error I'm getting:
Database_Exception [ 1452 ]: Cannot add or update a child row: a foreign key constraint
fails (`ddmachine`.`stocks_tags`, CONSTRAINT `fk_stock_tag` FOREIGN KEY (`tag_id`) REFERENCES
`tags` (`id`) ON DELETE CASCADE ON UPDATE CASCADE) [ INSERT INTO `stocks_tags` (`stock_id`,
`tag_id`) VALUES (19, 'cash') ]
I did see that someone else had a similar problem based on their enum columns but don't think that's it.
