title: Shrine 3.10.1

Bug fixes

• Since Shrine 3.9.0, the remove_invalid plugin would raise NoMethodError when validation failed on an attacher without a record and the model plugin was loaded (directly or through the activerecord/sequel plugins).

rb attacher = Shrine::Attacher.new attacher.assign(invalid_file) # NoMethodError: undefined method '=' for nil

Attacher#write from the model plugin is now a no-op when the attacher isn’t backed by a model, so the invalid file is removed and validation errors are kept as before.
