No, I meant that module defined in lib/active_scaffold/bridges/active_storage/
active_storage_helpers.rb, which has thumbnail_variant mattr accessor.
I was out of home and I couldn't test it before answering. I have tested now
and ActiveStorageBridgeHelpers is not loaded yet when initializer runs. You
could add require 'active_scaffold/bridges/active_storage/
active_storage_helpers' in initializer before that line, but I guess it should
be fixed in ActiveScaffold. I could add autoload lines in lib/active_scaffold/
bridges/active_storage.rb, but I guess it's better to define the setting in
ActiveScaffold::Bridges::ActiveStorage class.
I have changed thumbnail_variant definition in master branch, you can update
and use this line in initializer:
ActiveScaffold::Bridges::ActiveStorage.thumbnail_variant = {resize_to_limit:
[nil, 350]}
Regards,
Sergio
