ActiveStorage bridge was a contribution, I didn't write it, I haven't tried
ActiveStorage yet.
However, I can see form_ui is calling helper for list and show actions to
display content, as
other bridges related to file upload do.
Form_ui has this line:
content = active_scaffold_column_active_storage_has_one(record, column)
if
active_storage.attached?
That line display content with same helper as list and show. And that helper,
active_scaffold_column_active_storage_has_one method has this line:
attachment.attached? ? link_for_attachment(attachment) : nil
But link_for_attachment doesn't display thumbnail:
def link_for_attachment(attachment)
link_to(attachment.filename, rails_blob_url(attachment, disposition:
'attachment'),
target: '_blank')
end
I think that helper method must be changed to display thumbnail, as other
bridges do.
Carrierwave bridge display thumbnail, and thumbnail style name can be changed
in
bridge config. Paperclip do it in same way. Dragonfly do it in same way too,
but it allows to
set :thumb option in column's options. What is code to display thumbnail with
ActiveStorage?

Hi Sergio,
I'm using active storage plugin bridge in active scaffold.
But I don't have the thumbnail in form "mode" juste the name of the file. With
dragonfly I
have the thumbnail, do you know why ?
