Symfony FK Constraint Issue
So I have a table schema that has users who can be friends.
User:
actAs: { Timestampable: ~ }
columns:
name: { type: string(255), notnull: true }
email: { type: string(255), notnull: true, unique: true }
nickname: { type: string(255), unique: true }
password: { type: string(300), notnull: true }
image: { type: string(255) }
FriendsWith:
actAs: { Timestampable: ~ }
columns:
friend1_id: { type: integer, primary: true }
friend2_id: { type: integer, primary: true }
开发者_高级运维 relations:
User: { onDelete: CASCADE, local: friend1_id, foreign: id }
User: { onDelete: CASCADE, local: friend2_id, foreign: id }
It builds the database correctly, but when I try to insert test data like:
User:
user1:
name: Danny Gurt
email: comy19@gmail.com
nickname: danny
password: test1
user2:
name: Adrian Soian
email: adriansoian@gmail.com
nickname: adrian
password: test1
FriendsWith:
friendship1:
friend1_id: user1
friend2_id: user2
I get this integrity constraint problem:
SQLSTATE[23000]: Integrity constraint violation: 1452 Cannot add or update a child row: a foreign key constraint fails (`krowdd`.`friends_with`, CONSTRAINT `friends_with_ibfk_1` FOREIGN KEY (`friend1_id`) REFERENCES `user` (`id`) ON DELETE CASCADE)
Any ideas?
ADDITION:
I noticed the generated sql code is only showing one constraint for the friends_with table:
ALTER TABLE friends_with ADD CONSTRAINT friends_with_friend2_id_user_id FOREIGN KEY (friend2_id) REFERENCES user(id) ON DELETE CASCADE;
Maybe this will help!
Thanks!
Name the relations in your FriendsWith table differently so Doctrine can use them properly:
relations:
User1: { onDelete: CASCADE, local: friend1_id, foreign: id, foreignAlias: Friend1 }
User2: { onDelete: CASCADE, local: friend2_id, foreign: id, foreignAlias: Friend2 }
The numbers might not be the best names for the relations but you get the idea.
UPDATE - CODE:
This should do the job for you - note that I'm adding the relationship in the User table, not the FriendsWith table:
relations:
Friend1: {class: FriendsWith, local: id, foreign: friend1_id, type: many, foreignType: one, foreignAlias: User1, onDelete: CASCADE}
Friend2: {class: FriendsWith, local: id, foreign: friend2_id, type: many, foreignType: one, foreignAlias: User2, onDelete: CASCADE}
