I agree! 👍 When I added a new model without changing the existing one, everything went smoothly. However, issues arise when modifying the existing model. In such cases, migration becomes necessary.

Thank you so much for the insightful response 🙏 Thanks to what you mentioned, I was able to gain a deeper understanding of the material I'm studying. If it's okay with you, could you show me a simple example code that uses both Singleton and Dependency Injection together? I can't quite grasp the concept, so I wanted to ask. I hope you have a wonderful day/night 🌈✨
