---
|
||||
|
||||
### 7. ✅ QR Code Configuration System
|
||||
|
||||
**What was implemented**:
|
||||
- Automatic QR code generation on gateway creation
|
||||
- JSON payload with all configuration data:
|
||||
```json
|
||||
{
|
||||
"api_key": "gw_live_...",
|
||||
"api_base_url": "http://localhost:3000",
|
||||
"websocket_url": "ws://localhost:3000/cable",
|
||||
"version": "1.0"
|
||||
}
|
||||
```
|
||||
- High error correction level (L=H)
|
||||
- SVG format for quality scaling
|
||||
- Automatic URL detection (HTTP→WS, HTTPS→WSS)
|
||||
- Copy to clipboard for individual fields
|
||||
- "Copy All" button for complete configuration
|
||||
|
||||
**Benefits**:
|
||||
- No manual typing of long API keys
|
||||
- Reduces configuration errors
|
||||
- Faster gateway setup (scan QR code → done)
|
||||
- Works offline (QR code doesn't need network)
|
||||
|
||||
**Gem Added**:
|
||||
```ruby
|
||||
gem "rqrcode", "~> 2.0"
|
||||
```
|
||||

|
||||
|
||||
## Bug Fixes Applied
|
||||
|
||||
### Issue 1: Namespace Conflict - "Admin is not a module"
|
||||
|
||||
**Problem**: Model class `Admin` conflicted with `Admin` module namespace
|
||||
|
||||
**Solution**:
|
||||
- Renamed model: `Admin` → `AdminUser`
|
||||
- Renamed table: `admins` → `admin_users`
|
||||
- Updated all references in controllers, views, seeds, tests
|
||||
|
||||
**Files**:
|
||||
- Migration: `20251020031401_rename_admins_to_admin_users.rb`
|
||||
- Model: `app/models/admin_user.rb`
|
||||
- All admin controllers
|
||||
- `db/seeds.rb`
|
||||
|
||||
### Issue 2: undefined method 'flash'
|
||||
|
||||
**Problem**: Application in API-only mode disabled sessions and flash
|
||||
|
||||
**Solution**:
|
||||
- Disabled `config.api_only = true` in `config/application.rb`
|
||||
- Created `config/initializers/session_store.rb`
|
||||
- API controllers use `ActionController::API` (fast, stateless)
|
||||
- Admin controllers use `ActionController::Base` (full Rails features)
|
||||
|
||||
**Middleware Added**:
|
||||
- ActionDispatch::Cookies
|
||||
- ActionDispatch::Session::CookieStore
|
||||
- ActionDispatch::Flash
|
||||
|
||||
### Issue 3: undefined method 'logged_in?'
|
||||
|
||||
**Problem**: Helper methods not available in layout before controller runs
|
||||
|
||||
**Solution**:
|
||||
- Added `current_admin` and `logged_in?` to `ApplicationHelper`
|
||||
- Methods now globally available in all views
|
||||
|
||||
### Issue 4: undefined method 'stringify_keys' for String
|
||||
|
||||
**Problem**: JSONB fields sometimes returned String instead of Hash, causing serialization errors
|
||||
|
||||
**Solution**:
|
||||
- Added explicit attribute declarations to all models with JSONB fields:
|
||||
- `ApiKey` - `permissions` field
|
||||
- `Gateway` - `metadata` field
|
||||
- `OtpCode` - `metadata` field
|
||||
- `SmsMessage` - `metadata` field
|
||||
- Added `before_validation :ensure_*_is_hash` callbacks
|
||||
- Added defensive coding in views
|
||||
|
||||
**Pattern Applied**:
|
||||
```ruby
|
||||
class Model < ApplicationRecord
|
||||
attribute :jsonb_field, :jsonb, default: {}
|
||||
before_validation :ensure_jsonb_field_is_hash
|
||||
|
||||
private
|
||||
def ensure_jsonb_field_is_hash
|
||||
self.jsonb_field = {} if jsonb_field.nil?
|
||||
self.jsonb_field = {} unless jsonb_field.is_a?(Hash)
|
||||
end
|
||||
end
|
||||
```
|
||||
|
||||
### Issue 5: API Key Creation Stuck on /new Page
|
||||
|
||||
**Problem**: Form submission created key but didn't redirect properly
|
||||
|
||||
**Solution**:
|
||||
- Changed from `render :show` to `redirect_to` pattern
|
||||
- Added session storage for raw API key
|
||||
- Added `show` action to controller
|
||||
- Updated routes to include `:show`
|
||||
|
||||
**Same fix applied to Gateway creation for consistency**
|
||||

## Production Deployment Checklist
|
||||
|
||||
### Before Deploying
|
||||
|
||||
- [ ] Change default admin password
|
||||
- [ ] Set `config.force_ssl = true` in production.rb
|
||||
- [ ] Set secure `SECRET_KEY_BASE`
|
||||
- [ ] Configure proper `ALLOWED_ORIGINS` for CORS
|
||||
- [ ] Set up proper database backups
|
||||
- [ ] Configure Redis for production
|
||||
- [ ] Set up SSL certificates (Let's Encrypt)
|
||||
- [ ] Configure proper logging
|
||||
- [ ] Set up monitoring (e.g., New Relic, Datadog)
|
||||
- [ ] Test all features in staging first
|
||||
|
||||
### Environment Variables
|
||||
|
||||
```bash
|
||||
DATABASE_URL=postgresql://...
|
||||
REDIS_URL=redis://...
|
||||
SECRET_KEY_BASE=...
|
||||
RAILS_ENV=production
|
||||
RAILS_LOG_TO_STDOUT=enabled
|
||||
RAILS_SERVE_STATIC_FILES=enabled
|
||||
```
|
||||
|
||||
### Security Settings
|
||||
|
||||
```ruby
|
||||
# config/environments/production.rb
|
||||
config.force_ssl = true
|
||||
config.action_controller.default_url_options = { host: 'api.example.com', protocol: 'https' }
|
||||
```
|
||||

|
||||
|
||||
## Performance Considerations
|
||||
|
||||
### Database Indexes
|
||||
|
||||
All critical queries have indexes:
|
||||
- `admin_users.email` (unique)
|
||||
- `api_keys.key_digest` (unique)
|
||||
- `api_keys.key_prefix`
|
||||
- `gateways.device_id` (unique)
|
||||
- `sms_messages.message_id` (unique)
|
||||
- `sms_messages.status`
|
||||
- `sms_messages.phone_number`
|
||||
|
||||
### Pagination
|
||||
|
||||
- SMS logs: 50 per page (using Pagy)
|
||||
- Recent messages: Limited to 20
|
||||
- Can be adjusted in controllers
|
||||
|
||||
### Caching Opportunities
|
||||
|
||||
Not yet implemented, but recommended:
|
||||
- Dashboard statistics (cache for 5 minutes)
|
||||
- Gateway list (cache for 1 minute)
|
||||
- API key count (cache for 5 minutes)
|
||||
