Migration 010: Umbenennung (konsistente Terminologie) - training_styles → style_directions - exercise_styles → exercise_style_directions - training_style_target_groups → style_direction_target_groups - training_style_id → style_direction_id (in Junction-Tabellen) - Idempotent mit IF EXISTS checks Migration 011: Neue Dimension "Trainingsstil" - Neue Tabelle training_types (Breitensport, Leistungssport, Wettkampf) - Seed-Daten: 3 Standard-Trainingsstile - Junction-Tabelle exercise_training_types (M:N) - Indizes für Performance - ON DELETE RESTRICT: Training Types können nicht gelöscht werden wenn zugeordnet Architektur: - Fokusbereich (Karate) → Stilrichtung (Shotokan) → Trainingsstil (Breitensport) → Zielgruppe (Kinder) - Alle M:N für maximale Flexibilität - KI-freundlich: Flache Dimensionen, einfache Queries Version: 0.4.0 (BREAKING - nur DB-Migrationen, Backend/Frontend folgen)

-- Migration 010: Umbenennung "training_styles" → "style_directions"
|
|
-- Erstellt: 2026-04-23
|
|
-- Beschreibung: Konsistente Terminologie - "Stilrichtungen" statt "Trainingsstile"
|
|
-- Grund: "Trainingsstil" wird neue separate Dimension (Breitensport/Leistungssport)
|
|
|
|
-- ============================================================================
|
|
-- PHASE 1: Tabellen umbenennen
|
|
-- ============================================================================
|
|
|
|
-- Haupttabelle umbenennen
|
|
ALTER TABLE IF EXISTS training_styles RENAME TO style_directions;
|
|
|
|
-- Junction-Tabelle umbenennen
|
|
ALTER TABLE IF EXISTS exercise_styles RENAME TO exercise_style_directions;
|
|
|
|
-- Training-Style-Target-Groups Junction umbenennen
|
|
ALTER TABLE IF EXISTS training_style_target_groups RENAME TO style_direction_target_groups;
|
|
|
|
-- ============================================================================
|
|
-- PHASE 2: Spalten umbenennen
|
|
-- ============================================================================
|
|
|
|
-- In style_directions (vormals training_styles)
|
|
-- Keine Spalten-Umbennung nötig - parent_style_id kann bleiben (bedeutet parent_direction)
|
|
|
|
-- In exercise_style_directions (vormals exercise_styles)
|
|
DO $$
|
|
BEGIN
|
|
IF EXISTS (
|
|
SELECT 1 FROM information_schema.columns
|
|
WHERE table_name = 'exercise_style_directions' AND column_name = 'training_style_id'
|
|
) THEN
|
|
ALTER TABLE exercise_style_directions
|
|
RENAME COLUMN training_style_id TO style_direction_id;
|
|
END IF;
|
|
END $$;
|
|
|
|
-- In style_direction_target_groups (vormals training_style_target_groups)
|
|
DO $$
|
|
BEGIN
|
|
IF EXISTS (
|
|
SELECT 1 FROM information_schema.columns
|
|
WHERE table_name = 'style_direction_target_groups' AND column_name = 'training_style_id'
|
|
) THEN
|
|
ALTER TABLE style_direction_target_groups
|
|
RENAME COLUMN training_style_id TO style_direction_id;
|
|
END IF;
|
|
END $$;
|
|
|
|
-- ============================================================================
|
|
-- PHASE 3: Constraints umbenennen (automatisch durch ALTER TABLE)
|
|
-- ============================================================================
|
|
|
|
-- Foreign Key Constraints werden automatisch umbenannt
|
|
-- Indizes werden automatisch umbenannt
|
|
|
|
-- ============================================================================
|
|
-- PHASE 4: Validierung
|
|
-- ============================================================================
|
|
|
|
-- Nach dieser Migration:
|
|
-- - training_styles → style_directions
|
|
-- - exercise_styles → exercise_style_directions
|
|
-- - training_style_target_groups → style_direction_target_groups
|
|
-- - training_style_id → style_direction_id (in Junction-Tabellen)
|
|
|
|
-- Nächste Migration 011: Neue Dimension "training_types" (Breitensport/Leistungssport)
