How to get original from Mapped Data?

[LWlook]

I'm encountering an issue with the $request->safe() method while following the example described in the Spatie Laravel Data documentation.

Problem
When I make a request, the $request->safe() method returns an empty result, which suggests that the request is not being validated. I'm trying to understand how I can retrieve the validated data to save it to the database.

Current Approach
Currently, I use a data class to map data from the database to the response of a method. Additionally, I want to:

• Update the model with the same data class.
• Validate the data during this process.

Questions

• How can I ensure that the data is validated and retrieve the validated data using $request->safe()?
• Is there a different or better approach to achieve my goal of mapping, validating, and updating the model using the data class? How can I handle the situation where a field in the database has a different name than what is expected in the API's input and output?

Thank you for your assistance!
