This project explore the way to implement a generic type in Go

The generic type T in Java will the same as interface{} - concrete type

The other generic type as BaseModel will need a specific method of model for compiler recognize your generic type, example is GetId method in my case.

So whenever you need to pass a model to repo or service layer, and the object need to be a model, we will use as e.g

  func ReplaceOne(ctx context.Context, model BaseModel) {
      // replace your object to database
  }

The difficult step in this part is your models need to implement method GetID, we can use tool to generate, in case your models are following encapslution pattern (has getter setter method) this will be best place for this solution.
