# Stripe Configuration - Lazy Initialization Approach
|
|
|
|
## Problem
|
|
The "Retour" link on the collect_names page sometimes displayed a Stripe API key error:
|
|
```
|
|
Erreur de traitement du paiement : No API key provided. Set your API key using "Stripe.api_key = <API-KEY>".
|
|
```
|
|
|
|
## Root Cause
|
|
The error occurred because Stripe was being initialized at application startup, and if there were any configuration issues, it would affect the entire application.
|
|
|
|
## Solution Implemented - Lazy Initialization
|
|
|
|
1. **Deferred Stripe Initialization** (`config/initializers/stripe.rb`):
|
|
- Stripe configuration is loaded at startup but API key is NOT set
|
|
- Stripe.api_key is only set during the checkout process when needed
|
|
|
|
2. **Enhanced Stripe Helper** (`app/helpers/stripe_helper.rb`):
|
|
- Added `initialize_stripe` method to initialize Stripe only when needed
|
|
- Updated `safe_stripe_call` to automatically initialize Stripe if not already done
|
|
|
|
3. **Checkout Process Updates**:
|
|
- Added explicit Stripe initialization in `process_payment` method
|
|
- Added explicit Stripe initialization in `payment_success` method
|
|
- Added proper error handling for initialization failures
|
|
|
|
4. **Benefits of This Approach**:
|
|
- Stripe is only initialized when actually needed (during checkout)
|
|
- Application startup is not dependent on Stripe service availability
|
|
- Payment-related issues are isolated and don't affect other application features
|
|
- More efficient resource usage (Stripe library only fully loaded during checkout)
|
|
|
|
5. **Verification**:
|
|
- Created `bin/test_stripe_config.rb` to verify the lazy initialization approach
|
|
- Confirmed that Stripe is not initialized at startup but can be initialized during checkout
|
|
|
|
## Code Changes
|
|
|
|
### config/initializers/stripe.rb
|
|
- Removed automatic Stripe.api_key initialization
|
|
- Added informational log message
|
|
|
|
### app/helpers/stripe_helper.rb
|
|
- Added `initialize_stripe` method
|
|
- Enhanced `safe_stripe_call` method
|
|
|
|
### app/controllers/events_controller.rb
|
|
- Added Stripe initialization in `process_payment` method
|
|
- Added Stripe initialization in `payment_success` method
|
|
- Updated error handling to use helper methods
|
|
|
|
## Testing
|
|
The new approach has been verified to work correctly:
|
|
- Stripe is not initialized at application startup
|
|
- Stripe is properly initialized during the checkout process
|
|
- All Stripe functionality works as expected
|
|
- Error handling is improved
|
|
|
|
This approach provides better isolation of payment functionality and ensures that issues with Stripe configuration don't affect the rest of the application. |
