* M0 — Catalog : creation des tables `category_type` (referentiel) et `category`.
|
|
*
|
|
* Le referentiel `category_type` est cree vide ; ses valeurs seront seedees
|
|
* ulterieurement (cf. spec-back M0 § 9 HP-1).
|
|
*
|
|
* Index unique partiel sur (LOWER(name), category_type_id) WHERE deleted_at
|
|
* IS NULL : permet la recreation d'une categorie apres suppression logique
|
|
* (cf. RG-1.07). Postgres supporte nativement le `CREATE UNIQUE INDEX ... WHERE`.
|
|
*
|
|
* Les 4 colonnes Timestampable/Blamable (`created_at`, `updated_at`,
|
|
* `created_by`, `updated_by`) materialisent le pattern Shared (cf. ERP-52,
|
|
* spec-back M0 § 2.8) : NOT NULL pour les dates (remplies par le subscriber),
|
|
* nullable + ON DELETE SET NULL pour les FK user (creation hors contexte HTTP
|
|
* et suppression d'un user sans bloquer les categories existantes).
|
|
*
|
|
* Migration placee au namespace racine `DoctrineMigrations` (regle ABSOLUE
|
|
* Starseed n°11) : avec plusieurs migrations_paths, Doctrine Migrations 3.x
|
|
* trie par FQCN alphabetique et non par version timestamp → l'init des tables
|
|
* d'un module doit vivre au namespace racine pour garantir l'ordre sur base
|
|
* vide.
