Conditionally cache files in Rails asset pipeline

We have a custom preprocessor that we’ve injected into the asset pipeline which preprocesses specific filetypes successfully.

The problem is that our preprocessor will generate content dynamically so these precompiled assets should not be cached.

I am looking for a way to prevent *.myfiletype from ending up in the asset cache and always being preprocessed.

(This is only a development thing and in production should work like “normal”)

Thanks
