How can I get current model context in a FileNamer?

[pekka]

New to this library and trying to see whether it suits my needs. It looks great! I only have one doubt.

I have a Laravel app with several models that can have images.

However, I need the file names of the converted images to use data from the model they were uploaded for. So for example, an image for a Car model with the name Mercedes 500 SLK and a field color set to red might be mercedes-500-slk-color-red.jpg

Is this achievable using a FileNamer as explained here?

I'm not seeing a way to access the current model context.
