Laravel - Controllers
You need to inject both NotificationService and UserRepository into a Laravel controller and use them in multiple methods. What is the recommended approach?
AInject only one service via constructor and use Laravel's facade for the other.
BInject <code>NotificationService</code> in the constructor and resolve <code>UserRepository</code> manually inside each method.
CManually instantiate both services inside each controller method where needed.
DInject both services via the constructor and assign them to class properties.
Step-by-Step Solution
Solution:
Step 1: Use constructor injection for both dependencies
This ensures services are resolved once and available throughout the controller.
Step 2: Assign injected services to class properties
Allows easy access in any controller method without repeated resolution.
Final Answer:
Inject both services via the constructor and assign them to class properties. -> Option D
Quick Check:
Constructor injection for multiple dependencies [OK]
Quick Trick:Inject all dependencies in constructor for reuse [OK]
Common Mistakes:
Resolving dependencies manually inside methods
Instantiating services directly instead of injecting
Mixing injection and facades inconsistently
