-- Add Video Source Columns for YouTube/Embed Toggle
-- ============================================
-- This migration adds support for dual video sources (YouTube and Embed)
-- at the product level, allowing quick switching between sources

-- Add video source columns to bootcamp_lessons table
ALTER TABLE bootcamp_lessons
  ADD COLUMN IF NOT EXISTS youtube_url TEXT,
  ADD COLUMN IF NOT EXISTS embed_code TEXT;

-- Migrate existing video_url to youtube_url
UPDATE bootcamp_lessons
SET youtube_url = video_url
WHERE video_url IS NOT NULL
  AND youtube_url IS NULL;

-- Note: Keep old video_url column for backward compatibility
-- Can drop after verification if desired

-- Add video_source column to products table
ALTER TABLE products
  ADD COLUMN IF NOT EXISTS video_source TEXT DEFAULT 'youtube',
  ADD COLUMN IF NOT EXISTS video_source_config JSONB DEFAULT '{}';

-- Add constraint to ensure valid sources
ALTER TABLE products
  DROP CONSTRAINT IF EXISTS products_video_source_check;

ALTER TABLE products
  ADD CONSTRAINT products_video_source_check
  CHECK (video_source IN ('youtube', 'embed'));

-- Create index for faster queries
CREATE INDEX IF NOT EXISTS idx_products_video_source ON products(video_source);
