我有幾個表格:ingredients
,customers
,recipes
,menus
和restaurants
。CakePHP HABTM關係
的條件是:ingredients
HABTM customers
,recipes
HABTM ingredients
,menus
的hasMany recipes
和restaurants
的hasMany menus
。
但是,當我嘗試使用cmd控制檯烘烤所有食物時,自動創建的關係就像成分hasmany customers_ingredients,客戶hasmany customers_ingredients和customer_ingredients屬於客戶和成分,而不是提供成分hasandbelongtomany客戶。哪裏不對?表格定義或控制檯?
這裏我列出我創建表的語句:
CREATE TABLE customers (
id INT UNSIGNED AUTO_INCREMENT PRIMARY KEY,
cust_gname VARCHAR(20) NOT NULL,
cust_fname VARCHAR(30) NOT NULL,
cust_street VARCHAR(30) NOT NULL,
cust_suburb VARCHAR(30) NOT NULL,
cust_state VARCHAR(6) NOT NULL,
cust_postcode VARCHAR(4) NOT NULL,
cust_email VARCHAR(50) NOT NULL,
cust_phone VARCHAR(12),
cust_mobile VARCHAR(12)
);
CREATE TABLE restaurants (
id INT UNSIGNED AUTO_INCREMENT PRIMARY KEY,
name VARCHAR(30),
address1 VARCHAR(30),
address2 VARCHAR(30),
suburb VARCHAR(30),
state VARCHAR(10),
postcode VARCHAR(4)
);
CREATE TABLE ingredients (
id INT UNSIGNED AUTO_INCREMENT PRIMARY KEY,
name VARCHAR(30)
);
CREATE TABLE menus (
id INT UNSIGNED AUTO_INCREMENT PRIMARY KEY,
description VARCHAR(30),
restaurant_id INT UNSIGNED,
CONSTRAINT fk_restID FOREIGN KEY (restaurant_id) REFERENCES restaurants(id)
);
CREATE TABLE recipes (
id INT UNSIGNED AUTO_INCREMENT PRIMARY KEY,
name VARCHAR(30),
menu_id INT UNSIGNED,
image VARCHAR(30),
CONSTRAINT fk_menuID FOREIGN KEY (menu_id) REFERENCES menus(id)
);
CREATE TABLE ingredient_recipes (
id INT UNSIGNED AUTO_INCREMENT PRIMARY KEY,
ingredient_id INT UNSIGNED,
recipe_id INT UNSIGNED,
CONSTRAINT fk_ingID FOREIGN KEY (ingredient_id) REFERENCES ingredients(id),
CONSTRAINT fk_recID FOREIGN KEY (recipe_id) REFERENCES recipes(id)
);
CREATE TABLE customer_ingredients (
id INT UNSIGNED AUTO_INCREMENT PRIMARY KEY,
customer_id INT UNSIGNED,
ingredient_id INT UNSIGNED,
CONSTRAINT fk_ingrID FOREIGN KEY (ingredient_id) REFERENCES ingredients(id),
CONSTRAINT fk_cusID FOREIGN KEY (customer_id) REFERENCES customers(id)
);
這解決了問題。非常感謝! –
