Question

I’m trying to model a user which could be invited by another user. So I set up one-to-many self reference in my doctrine model.

User:
  tableName: users
  actAs:
    Timestampable:
  columns:
    id:
      type: integer(11)
      primary: true
      autoincrement: true
    name:
      type: string(255)
      unique: true
    password:
      type: string(255)
    email:
      type: string(255)
    [...]
    invited_by:
      type: integer(11)
  relations:
    Inviter:
      class: User
      type: one
      local: invited_by
      foreign: id
      foreignAlias: Invitees
      onDelete: SET NULL
      onUpdate: CASCADE
  options:
    type: InnoDB
    collate: utf8_unicode_ci
    charset: utf8

This works just fine in MySQL, but if I try to save the record using the User objects save()-method in Postgres the following error is thrown:

SQLSTATE[42P01]: Undefined table: 7 FEHLER: Relation »users_id«
existiert nicht LINE 1: SELECT CURRVAL(‘users_id’) ^. Failing Query:
“SELECT CURRVAL(‘users_id’)”

I think it is something related to the self reference, but I can’t find a mistake in my modeling. Anyone an idea on this?

Answer 1

The default name of a sequence attached to a serial column is tablename_colname_seq
currval is for retrieving the “current value” of a sequence.
So it would have to be:

SELECT currval('users_id_seq')

Your whole syntax is obviously made out for MySQL. Things like type: InnoDB, integer(11) or autoincrement don’t make sense in Postgres.
