-- Migration: Add Menu Action Access System
-- Description: Create menu_actions, user_level_menu_accesses, and user_level_menu_action_accesses tables
-- Date: 2026-01-16

-- ============================================================================
-- Step 1: Create menu_actions table
-- ============================================================================
CREATE TABLE IF NOT EXISTS menu_actions (
    id SERIAL PRIMARY KEY,
    menu_id INT NOT NULL,
    action_code VARCHAR(50) NOT NULL,
    action_name VARCHAR(255) NOT NULL,
    description TEXT NULL,
    path_url VARCHAR(255) NULL,
    http_method VARCHAR(10) NULL,
    position INT NULL,
    client_id UUID NULL,
    is_active BOOLEAN DEFAULT TRUE,
    created_at TIMESTAMP DEFAULT NOW(),
    updated_at TIMESTAMP DEFAULT NOW(),
    FOREIGN KEY (menu_id) REFERENCES master_menus(id) ON DELETE CASCADE,
    UNIQUE(menu_id, action_code, COALESCE(client_id, '00000000-0000-0000-0000-000000000000'::UUID))
);

-- Add indexes for performance
CREATE INDEX idx_menu_actions_menu_id ON menu_actions(menu_id);
CREATE INDEX idx_menu_actions_action_code ON menu_actions(action_code);
CREATE INDEX idx_menu_actions_client_id ON menu_actions(client_id) WHERE client_id IS NOT NULL;
CREATE INDEX idx_menu_actions_is_active ON menu_actions(is_active);

-- Add comments
COMMENT ON TABLE menu_actions IS 'Actions yang tersedia di setiap menu (view, create, edit, delete, approve, export, etc)';
COMMENT ON COLUMN menu_actions.menu_id IS 'Foreign key ke master_menus';
COMMENT ON COLUMN menu_actions.action_code IS 'Kode action: view, create, edit, delete, approve, export, etc';
COMMENT ON COLUMN menu_actions.action_name IS 'Nama action yang ditampilkan ke user';
COMMENT ON COLUMN menu_actions.path_url IS 'Optional: URL path untuk routing frontend';
COMMENT ON COLUMN menu_actions.http_method IS 'Optional: HTTP method (GET, POST, PUT, DELETE)';

-- ============================================================================
-- Step 2: Create user_level_menu_accesses table
-- ============================================================================

-- Add indexes for performance

COMMENT ON COLUMN user_level_menu_accesses.menu_id IS 'Foreign key ke master_menus';
COMMENT ON COLUMN user_level_menu_accesses.can_access IS 'Apakah user level boleh mengakses menu ini';

-- ============================================================================
-- Step 3: Create user_level_menu_action_accesses table
-- ============================================================================

-- Step 4: Create trigger for updated_at
