A way could be using JS to display error messages instead of replacing form,
although
fields won't get any class to highlight them with CSS, unless JS make some
changes to
existing fields too.

I think you can override that helper in your controller helper, or
ApplicationHelper. I think
it should work as dragonfly does, there should be a thumbnail_variant setting
in
ActiveScaffold::Bridges::ActiveStorage::ActiveStorageBridgeHelpers, default to
something
like {resize_to_limit: [nil, 30]} to use same values as dragonfly bridge.
I have added this to master branch. However, I have checked docs for
activestorage in rails
5.2 and I don't see resize_to_limit option, did it changed in 6.0?
I'm not sure what you want about the other question. Do you want to keep
uploaded file
so user doesn't need to upload it again? Or do you want to have input file
prefilled so user
doesn't have to browse file to upload again? The former, I don't know, does it
rails save
attachment into active_storage_blobs table? It could be orphaned if form is not
submitted
again. The latter, I think it isn't possible, I think browser doesn't allow to
set value attribute
for input file tag.

something like that image_tag user.avatar.variant(resize_to_limit: [100, 100])
Where can I override the helper link_for_attachment(attachment) ?
and for the other question do you have a clue how to do it ? (

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 ?
