# Collaborative Webinar Implementation Guide (FIXED)

**Project:** WithDwindi Learning Hub - Collaboration Feature
**Date:** February 2, 2026
**Architecture:** Wallet-based profit tracking system

**CRITICAL FIX:** Corrected migration order to resolve dependencies properly

---

## Migration Execution Order (READ THIS FIRST!)

**Execute migrations in THIS exact order:**

1. ✅ Platform settings extension (no dependencies)
2. ✅ Profile fields (no dependencies)
3. ✅ User access enhancement (no dependencies)
4. ✅ Products collaboration fields (no dependencies)
5. ✅ **Wallet tables** (MUST be first - creates the tables others reference)
6. ✅ Wallet functions (needs wallet tables)
7. ✅ Order items profit fields (references wallet_transactions - now exists)
8. ✅ Withdrawals table (references wallet_transactions - now exists)
9. ✅ Collaborator profits view (references wallet_transactions - now exists)
10. ✅ Triggers (needs products and wallets)

---

## Migration 1: Extend Platform Settings (DO THIS FIRST)

**Why first:** No dependencies, other migrations/functions will read these fields from `platform_settings`

```sql
-- Add owner + collaboration fields into existing platform_settings table
ALTER TABLE platform_settings
  ADD COLUMN IF NOT EXISTS owner_name TEXT DEFAULT 'Dwindi',
  ADD COLUMN IF NOT EXISTS owner_avatar_url TEXT DEFAULT '',
  ADD COLUMN IF NOT EXISTS collaboration_enabled BOOLEAN DEFAULT true,
  ADD COLUMN IF NOT EXISTS min_withdrawal_amount INTEGER DEFAULT 100000,
  ADD COLUMN IF NOT EXISTS default_profit_share INTEGER DEFAULT 50,
  ADD COLUMN IF NOT EXISTS max_pending_withdrawals INTEGER DEFAULT 1,
  ADD COLUMN IF NOT EXISTS withdrawal_processing_days INTEGER DEFAULT 3;

-- Backfill nulls for existing rows
UPDATE platform_settings
SET
  owner_name = COALESCE(owner_name, 'Dwindi'),
  owner_avatar_url = COALESCE(owner_avatar_url, ''),
  collaboration_enabled = COALESCE(collaboration_enabled, true),
  min_withdrawal_amount = COALESCE(min_withdrawal_amount, 100000),
  default_profit_share = COALESCE(default_profit_share, 50),
  max_pending_withdrawals = COALESCE(max_pending_withdrawals, 1),
  withdrawal_processing_days = COALESCE(withdrawal_processing_days, 3);

COMMENT ON COLUMN platform_settings.owner_name IS 'Owner/Host name displayed on webinar cards';
COMMENT ON COLUMN platform_settings.owner_avatar_url IS 'Owner/Host avatar URL displayed on webinar cards';
COMMENT ON COLUMN platform_settings.collaboration_enabled IS 'Enable collaboration feature globally';
COMMENT ON COLUMN platform_settings.min_withdrawal_amount IS 'Minimum withdrawal amount in IDR';
COMMENT ON COLUMN platform_settings.default_profit_share IS 'Default profit share percentage for collaborator';
COMMENT ON COLUMN platform_settings.max_pending_withdrawals IS 'Maximum pending withdrawals per collaborator';
COMMENT ON COLUMN platform_settings.withdrawal_processing_days IS 'Expected withdrawal processing time in business days';
```

**Execute:** Copy-paste into Supabase SQL Editor → Run

---

## Migration 2: Add Collaborator Profile Fields

**Why second:** No dependencies, needs to exist before collaborators can be created

```sql
-- Add bank account fields to profiles table
ALTER TABLE profiles
  ADD COLUMN IF NOT EXISTS bio TEXT,
  ADD COLUMN IF NOT EXISTS portfolio_url TEXT,
  ADD COLUMN IF NOT EXISTS bank_account_number VARCHAR(50),
  ADD COLUMN IF NOT EXISTS bank_account_name VARCHAR(100),
  ADD COLUMN IF NOT EXISTS bank_name VARCHAR(50);

-- Add constraint for valid URLs
DO $$
BEGIN
  IF NOT EXISTS (
    SELECT 1 FROM pg_constraint WHERE conname = 'valid_portfolio_url'
  ) THEN
    ALTER TABLE profiles ADD CONSTRAINT valid_portfolio_url
    CHECK (portfolio_url IS NULL OR portfolio_url ~* '^https?://');
  END IF;
END $$;

-- Add comments
COMMENT ON COLUMN profiles.bio IS 'Collaborator bio/description';
COMMENT ON COLUMN profiles.portfolio_url IS 'Collaborator portfolio URL';
COMMENT ON COLUMN profiles.bank_account_number IS 'Collaborator bank account for withdrawals';
COMMENT ON COLUMN profiles.bank_account_name IS 'Bank account holder name (must match ID)';
COMMENT ON COLUMN profiles.bank_name IS 'Bank name (e.g., BCA, Mandiri, BNI)';
```

**Execute:** Copy-paste into Supabase SQL Editor → Run

---

## Migration 3: Enhance User Access Table

**Why third:** No dependencies, needs to exist before we grant collaborator access

```sql
-- Add tracking fields to user_access table
ALTER TABLE user_access
  ADD COLUMN IF NOT EXISTS access_type VARCHAR(20) DEFAULT 'purchase' CHECK (access_type IN ('purchase', 'collaborator', 'admin', 'manual')),
  ADD COLUMN IF NOT EXISTS granted_by UUID REFERENCES auth.users(id);

-- Update existing records to 'purchase'
UPDATE user_access SET access_type = 'purchase' WHERE access_type IS NULL;

-- Add index for collaborator access queries
CREATE INDEX IF NOT EXISTS idx_user_access_type ON user_access(user_id, access_type);

COMMENT ON COLUMN user_access.access_type IS 'How access was granted: purchase, collaborator, admin, or manual';
COMMENT ON COLUMN user_access.granted_by IS 'User who granted this access (for collaborator/manual)';
```

**Execute:** Copy-paste into Supabase SQL Editor → Run

---

## Migration 4: Add Collaboration Fields to Products

**Why fourth:** No dependencies, needs to exist before wallet trigger (Migration 10)

```sql
-- Add collaboration fields to products table
ALTER TABLE products
  ADD COLUMN IF NOT EXISTS collaborator_user_id UUID REFERENCES auth.users(id) ON DELETE SET NULL,
  ADD COLUMN IF NOT EXISTS profit_share_percentage INTEGER DEFAULT 0 CHECK (profit_share_percentage >= 0 AND profit_share_percentage <= 100),
  ADD COLUMN IF NOT EXISTS host_share_percentage INTEGER GENERATED ALWAYS AS (100 - profit_share_percentage) STORED,
  ADD COLUMN IF NOT EXISTS auto_grant_access BOOLEAN DEFAULT true;

-- Add index for collaborator queries
CREATE INDEX IF NOT EXISTS idx_products_collaborator ON products(collaborator_user_id) WHERE collaborator_user_id IS NOT NULL;

COMMENT ON COLUMN products.collaborator_user_id IS 'Collaborator user ID (null if solo product)';
COMMENT ON COLUMN products.profit_share_percentage IS 'Profit share percentage for collaborator (0-100)';
COMMENT ON COLUMN products.auto_grant_access IS 'Automatically grant product access to collaborator';
```

**Execute:** Copy-paste into Supabase SQL Editor → Run

---

## Migration 5: Create Wallet Tables (CRITICAL - DO THIS BEFORE ANYTHING ELSE)

**Why fifth:** **Creates `wallet_transactions` and `collaborator_wallets`** that other migrations reference

```sql
-- Create collaborator wallets table
CREATE TABLE IF NOT EXISTS collaborator_wallets (
  user_id UUID PRIMARY KEY REFERENCES auth.users(id) ON DELETE CASCADE,
  current_balance DECIMAL(12,2) NOT NULL DEFAULT 0,
  total_earned DECIMAL(12,2) NOT NULL DEFAULT 0,
  total_withdrawn DECIMAL(12,2) NOT NULL DEFAULT 0,
  pending_balance DECIMAL(12,2) NOT NULL DEFAULT 0,
  updated_at TIMESTAMPTZ DEFAULT NOW()
);

-- Create index for balance queries
CREATE INDEX IF NOT EXISTS idx_wallets_balance ON collaborator_wallets(current_balance);

-- Enable RLS
ALTER TABLE collaborator_wallets ENABLE ROW LEVEL SECURITY;

DROP POLICY IF EXISTS "Users can view own wallet" ON collaborator_wallets;
DROP POLICY IF EXISTS "Admins can view all wallets" ON collaborator_wallets;

CREATE POLICY "Users can view own wallet"
  ON collaborator_wallets FOR SELECT
  USING (auth.uid() = user_id);

CREATE POLICY "Admins can view all wallets"
  ON collaborator_wallets FOR SELECT
  USING (
    EXISTS (
      SELECT 1 FROM user_roles
      WHERE user_id = auth.uid() AND role = 'admin'
    )
  );

COMMENT ON TABLE collaborator_wallets IS 'Collaborator wallet balances';
COMMENT ON COLUMN collaborator_wallets.current_balance IS 'Available balance (can be withdrawn)';
COMMENT ON COLUMN collaborator_wallets.pending_balance IS 'Balance in pending withdrawals';
COMMENT ON COLUMN collaborator_wallets.total_earned IS 'Lifetime earnings from all collaborative sales';

-- Create wallet transactions table (audit trail)
CREATE TABLE IF NOT EXISTS wallet_transactions (
  id UUID PRIMARY KEY DEFAULT gen_random_uuid(),
  user_id UUID NOT NULL REFERENCES auth.users(id) ON DELETE CASCADE,
  order_id UUID REFERENCES orders(id) ON DELETE SET NULL,
  order_item_id UUID REFERENCES order_items(id) ON DELETE SET NULL,
  -- Keep this as plain UUID for now; FK is added in Migration 8 after withdrawals exists
  withdrawal_id UUID,
  transaction_type VARCHAR(20) NOT NULL CHECK (transaction_type IN ('credit', 'debit', 'withdrawal', 'refund')),
  amount DECIMAL(12,2) NOT NULL CHECK (amount > 0),
  balance_after DECIMAL(12,2) NOT NULL,
  status VARCHAR(20) DEFAULT 'completed' CHECK (status IN ('pending', 'completed', 'failed', 'reversed')),
  description TEXT,
  metadata JSONB,
  created_at TIMESTAMPTZ DEFAULT NOW(),
  updated_at TIMESTAMPTZ DEFAULT NOW()
);

-- Create indexes
CREATE INDEX IF NOT EXISTS idx_wallet_transactions_user ON wallet_transactions(user_id, created_at DESC);
CREATE INDEX IF NOT EXISTS idx_wallet_transactions_order ON wallet_transactions(order_id);
CREATE INDEX IF NOT EXISTS idx_wallet_transactions_withdrawal ON wallet_transactions(withdrawal_id) WHERE withdrawal_id IS NOT NULL;
CREATE INDEX IF NOT EXISTS idx_wallet_transactions_type ON wallet_transactions(transaction_type, created_at DESC);

-- Enable RLS
ALTER TABLE wallet_transactions ENABLE ROW LEVEL SECURITY;

DROP POLICY IF EXISTS "Users can view own transactions" ON wallet_transactions;
DROP POLICY IF EXISTS "Admins can view all transactions" ON wallet_transactions;

CREATE POLICY "Users can view own transactions"
  ON wallet_transactions FOR SELECT
  USING (auth.uid() = user_id);

CREATE POLICY "Admins can view all transactions"
  ON wallet_transactions FOR SELECT
  USING (
    EXISTS (
      SELECT 1 FROM user_roles
      WHERE user_id = auth.uid() AND role = 'admin'
    )
  );

COMMENT ON TABLE wallet_transactions IS 'Wallet transaction history for audit trail';
COMMENT ON COLUMN wallet_transactions.transaction_type IS 'credit: earned, debit: refunded, withdrawal: requested withdrawal';
COMMENT ON COLUMN wallet_transactions.balance_after IS 'Wallet balance after this transaction';
COMMENT ON COLUMN wallet_transactions.metadata IS 'Additional data (e.g., order details, product info)';
```

**Execute:** Copy-paste into Supabase SQL Editor → Run

**✅ CRITICAL:** **This must be completed BEFORE migrations 6-10!**

## Migration 6: Create Wallet Functions

**Why sixth:** Needs `wallet_transactions` and `collaborator_wallets` tables (created in Migration 5)

## Migration 7: Add Profit Fields to Order Items

**Why seventh:** References `wallet_transactions(id)` which now exists (created in Migration 5)

```sql
-- Add profit split fields to order_items table (not orders)
ALTER TABLE order_items
  ADD COLUMN IF NOT EXISTS host_share DECIMAL(12,2) DEFAULT 0,

COMMENT ON COLUMN order_items.collaborator_share IS 'Collaborator profit amount from this order item';
COMMENT ON COLUMN order_items.wallet_transaction_id IS 'Reference to wallet transaction that credited this profit';

## Migration 8: Create Withdrawals Table

**Why eighth:** References `wallet_transactions(id)` and then adds back FK from `wallet_transactions.withdrawal_id` after `withdrawals` exists

```sql
-- Create withdrawals table

## Migration 9: Create Collaborator Profits View

**Why ninth:** References `wallet_transactions` which now exists (created in Migration 5)

```sql
-- Create or replace view for collaborator profits (privacy-protected)
CREATE OR REPLACE VIEW collaborator_profits AS

# Phase 3: Verification Tests

## Test 1: Verify Wallet Tables

```sql
-- Check if tables exist
SELECT table_name
FROM information_schema.tables
WHERE table_schema = 'public'
  AND table_name IN ('collaborator_wallets', 'wallet_transactions')
ORDER BY table_name;

-- Should return both tables
```

## Test 2: Verify Wallet Functions

```sql
-- Test collaboration settings retrieval (reads from platform_settings)
SELECT * FROM get_collaboration_settings();

-- Should return all 5 collaboration settings with correct types
```

## Test 3: Test Wallet Creation Trigger

```sql
-- This should auto-create a wallet for the collaborator
INSERT INTO products (title, slug, type, description, price, collaborator_user_id, profit_share_percentage)
VALUES ('Test Collab', 'test-collab', 'webinar', 'Test', 100000, 'YOUR_USER_ID', 50);

-- Check if wallet was created
SELECT * FROM collaborator_wallets WHERE user_id = 'YOUR_USER_ID';

-- Should return: user_id with 0 balances
```

## Test 4: Test Credit Function

```sql
-- You'll need a real order_item_id for this
SELECT credit_collaborator_wallet(
  'YOUR_USER_ID',                    -- p_user_id
  'YOUR_ORDER_ITEM_ID',              -- p_order_item_id
  50000,                             -- p_amount
  'Test profit credit'                -- p_description
);

-- Check wallet balance
SELECT * FROM get_collaborator_wallet('YOUR_USER_ID');

-- Check transaction history
SELECT * FROM wallet_transactions WHERE user_id = 'YOUR_USER_ID' ORDER BY created_at DESC;
```

## Test 5: Test Owner Identity Function

```bash
# Via curl
curl https://YOUR_PROJECT_REF.supabase.co/functions/v1/get-owner-identity

# Should return:
# {"owner_name":"Dwindi","owner_avatar_url":""}
```
