# Database Seeding

## Overview

The database seeding process populates initial data required for the application to function. Seeding runs automatically after migrations in development but must be run manually in production.

**Seed Script:** `api/prisma/seed.ts`

**Seed Data:**
- Default super admin user
- Default map settings (Edmonton coordinates)
- 6 page blocks for landing page builder
- 4 email templates (campaign email, response verification, shift signup confirmation, shift details reminder)

---

## Running Seed

### Development
```bash
cd api
npm run seed
# OR
npx prisma db seed
```

### Production (Docker)
```bash
docker compose exec api npx prisma db seed
```

### CI/CD
Seed runs automatically after `prisma migrate deploy` if configured in `package.json`:
```json
{
  "prisma": {
    "seed": "ts-node prisma/seed.ts"
  }
}
```

## Seed Data Details

### 1. Default Admin User

**Email:** `admin@cmlite.org`
**Password:** `ChangeMe2025!`
**Role:** `SUPER_ADMIN`
**Status:** `ACTIVE`
**Email Verified:** `true`

**Code:**
```typescript
const hashedPassword = await bcrypt.hash('ChangeMe2025!', 10);

const admin = await prisma.user.upsert({
  where: { email: 'admin@cmlite.org' },
  update: {
    password: hashedPassword,
    emailVerified: true,
    status: 'ACTIVE',
  },
  create: {
    email: 'admin@cmlite.org',
    password: hashedPassword,
    name: 'Admin',
    role: UserRole.SUPER_ADMIN,
    emailVerified: true,
  },
});
```

**Security Note:** Change default password immediately after first login!

### 2. Default Map Settings

**ID:** `default` (singleton)
**Coordinates:** Edmonton, AB (53.5461°N, 113.4938°W)
**Zoom:** 11
**Walk Sheet:** Blank titles/footers

**Code:**
```typescript
await prisma.mapSettings.upsert({
  where: { id: 'default' },
  update: {},
  create: {
    id: 'default',
    latitude: 53.5461,
    longitude: -113.4938,
    zoom: 11,
    walkSheetTitle: 'Walk Sheet',
    walkSheetSubtitle: '',

  },
});
```

### 3. Page Blocks (6 blocks)

}
```

### 4. Email Templates (4 templates)

#### Campaign Email to Representative
**Key:** `campaign-email`
**Category:** `INFLUENCE`
**Variables:** CAMPAIGN_TITLE, MESSAGE, USER_NAME, USER_EMAIL, POSTAL_CODE, RECIPIENT_NAME, RECIPIENT_LEVEL, ORGANIZATION_NAME, TIMESTAMP

**File Locations:**
- HTML: `api/src/templates/email/campaign-email.html`
- Text: `api/src/templates/email/campaign-email.txt`

**Seeding Logic:**
```typescript
const templateDef = {
  key: 'campaign-email',
  name: 'Campaign Email to Representative',
  description: 'Email sent when a constituent contacts their elected representative through a campaign',
  category: EmailTemplateCategory.INFLUENCE,
  subjectLine: '{{CAMPAIGN_TITLE}} - Message from {{USER_NAME}}',
  isSystem: true,
  variables: [
    { key: 'CAMPAIGN_TITLE', label: 'Campaign Title', isRequired: true, sampleValue: 'Support Climate Action Bill C-12' },
    { key: 'MESSAGE', label: 'Message Body', isRequired: true, sampleValue: 'I urge you to support...' },
    // ... 7 more variables
  ],
};

const htmlContent = fs.readFileSync(path.join(templatesDir, `${templateDef.key}.html`), 'utf-8');
const textContent = fs.readFileSync(path.join(templatesDir, `${templateDef.key}.txt`), 'utf-8');

const template = await prisma.emailTemplate.create({
  data: {
    ...templateDef,
    htmlContent,
    textContent,
    createdByUserId: admin.id,
    variables: {
      create: templateDef.variables,
    },
  },
});
```

**Variables:** ORGANIZATION_NAME, USER_NAME, USER_EMAIL, SHIFT_TITLE, SHIFT_DATE, SHIFT_TIME, SHIFT_LOCATION, IS_NEW_USER, TEMP_PASSWORD, LOGIN_URL

#### Shift Details Reminder
**Key:** `shift-details`
**Category:** `MAP`
**Variables:** ORGANIZATION_NAME, USER_NAME, SHIFT_TITLE, SHIFT_DATE, SHIFT_START_TIME, SHIFT_END_TIME, SHIFT_LOCATION, SHIFT_DESCRIPTION, CURRENT_VOLUNTEERS, MAX_VOLUNTEERS, SHIFT_STATUS

## Seed Script Structure

### Main Function
```typescript
async function main() {
  console.log('Seeding database...');

  // 1. Create admin user
  const admin = await createAdminUser();

  // 2. Create map settings
  await createMapSettings();

  // 3. Create page blocks
  await createPageBlocks();

  // 4. Seed email templates
  await seedEmailTemplates(admin);

  console.log('Seed complete.');
}
```

### Upsert Pattern
All seed operations use `upsert` to be idempotent:
```typescript
await prisma.pageBlock.upsert({
  where: { id: block.id },
  update: {},  // Don't update if exists
  create: block,  // Create if doesn't exist
});
```

**Benefits:**
- Safe to run multiple times
- Won't duplicate data
- Won't overwrite user changes (empty `update` clause)

### Error Handling
```typescript
main()
  .catch((e) => {
    console.error('Seed error:', e);
    process.exit(1);
  })
  .finally(async () => {
    await prisma.$disconnect();
  });
```

## Customizing Seed Data

### Change Admin Credentials
Edit `api/prisma/seed.ts`:
```typescript
const hashedPassword = await bcrypt.hash('YourSecurePassword123!', 10);

const admin = await prisma.user.upsert({
  where: { email: 'your-email@example.com' },  // Change email
  update: {
    password: hashedPassword,
    emailVerified: true,
    status: 'ACTIVE',
  },
  create: {
    email: 'your-email@example.com',  // Change email
    password: hashedPassword,
    name: 'Your Name',  // Change name
    role: UserRole.SUPER_ADMIN,
    emailVerified: true,
  },
});
```

### Change Map Default Location
Edit `api/prisma/seed.ts`:
```typescript
await prisma.mapSettings.upsert({
  where: { id: 'default' },
  update: {},
  create: {
    id: 'default',
    latitude: 51.0447,    // Calgary, AB
    longitude: -114.0719,
    zoom: 11,
    walkSheetTitle: 'Calgary Canvass Walk Sheet',
    walkSheetSubtitle: 'District Canvassing',
    walkSheetFooter: 'Thank you for volunteering!',
  },
});
```

### Add Custom Page Blocks
```typescript
const customBlocks = [
  {
    id: 'custom-video',
    type: 'video',
    label: 'Video Embed',
    category: 'Media',
    sortOrder: 7,
    schema: {
      videoUrl: { type: 'string', label: 'Video URL' },
      caption: { type: 'string', label: 'Caption' },
    },
    defaults: {
      videoUrl: 'https://www.youtube.com/embed/...',
      caption: 'Watch our video',
    },
  },
];

for (const block of customBlocks) {
  await prisma.pageBlock.upsert({
    where: { id: block.id },
    update: {},
    create: block,
  });
}
```

---

## Verifying Seed Data

### Check Admin User
```bash
docker compose exec api npx prisma studio
# Navigate to users table, filter by role = "SUPER_ADMIN"
```

### Check Map Settings
```bash
docker compose exec v2-postgres psql -U changemaker_v2 changemaker_v2 -c "SELECT * FROM map_settings;"
```

### Check Page Blocks
```bash
docker compose exec v2-postgres psql -U changemaker_v2 changemaker_v2 -c "SELECT id, type, label FROM page_blocks ORDER BY sort_order;"
```

### Check Email Templates
```bash
docker compose exec v2-postgres psql -U changemaker_v2 changemaker_v2 -c "SELECT key, name, category FROM email_templates;"
```

---

## Troubleshooting

### Error: "Unique constraint failed on email"
**Cause:** Admin user already exists
**Solution:** Seed uses `upsert`, so this shouldn't happen. Check seed script for typos.

### Error: "Template files not found"
**Cause:** Email template `.html`/`.txt` files missing
**Solution:** Ensure `api/src/templates/email/` directory contains:
- `campaign-email.html`
- `campaign-email.txt`
- `response-verification.html`
- `response-verification.txt`
- `shift-signup-confirmation.html`
- `shift-signup-confirmation.txt`
- `shift-details.html`
- `shift-details.txt`

### Error: "Cannot find module 'bcryptjs'"
**Cause:** Dependencies not installed
**Solution:**
```bash
cd api && npm install
```

### Seed doesn't run after migration
**Cause:** `package.json` missing `prisma.seed` config
**Solution:** Add to `api/package.json`:
```json
{
  "prisma": {
    "seed": "ts-node prisma/seed.ts"
  }
}
```

## Production Seeding

### Initial Deployment
```bash
# 1. Deploy migrations
docker compose exec api npx prisma migrate deploy

# 2. Run seed
docker compose exec api npx prisma db seed

# 3. Change admin password immediately
# Login at https://app.cmlite.org with admin@cmlite.org / ChangeMe2025!
# Navigate to /app/profile, update password
```

### Subsequent Deployments
**Don't re-run seed** unless adding new seed data (new page blocks, email templates, etc.). Existing seed data uses `upsert` with empty `update` clause, so it won't overwrite user changes.
