Mysql: ERROR 1005 (HY000): 无法创建表 'receitascakephp.recipes' (errno: 150)

Question

CREATE TABLE `users` (
`id` INT NOT NULL PRIMARY KEY AUTO_INCREMENT,
`name` VARCHAR(255) NOT NULL,
    `username` VARCHAR(75) NOT NULL,
    `password` VARCHAR(75) NOT NULL,
    `image` VARCHAR(255)
);

CREATE TABLE `recipes` (
    `id` INT NOT NULL PRIMARY KEY AUTO_INCREMENT,
    `name` VARCHAR(255) NOT NULL,
    `method` TEXT NOT NULL,
    `image` VARCHAR(255),
    `user_id` INT NOT NULL,
    CONSTRAINT `fk_recipes_users` FOREIGN KEY(`user_id`) REFERENCES `users`(`id`) ON DELETE CASCADE
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

我不知道为什么，但我得到:

ERROR 1005 (HY000): Can't create table 'receitascakephp.recipes' (errno: 150)

Answer 1

两个表都需要是 InnoDB:

CREATE TABLE `users` (
`id` INT NOT NULL PRIMARY KEY AUTO_INCREMENT,
`name` VARCHAR(255) NOT NULL,
    `username` VARCHAR(75) NOT NULL,
    `password` VARCHAR(75) NOT NULL,
    `image` VARCHAR(255)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

CREATE TABLE `recipes` (
    `id` INT NOT NULL PRIMARY KEY AUTO_INCREMENT,
    `name` VARCHAR(255) NOT NULL,
    `method` TEXT NOT NULL,
    `image` VARCHAR(255),
    `user_id` INT NOT NULL,
    CONSTRAINT `fk_recipes_users` FOREIGN KEY(`user_id`) REFERENCES `users`(`id`) ON DELETE CASCADE
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
