Remove Attachment
The remove_attachment
plugin allows you to delete
attachments through checkboxes on the web form.
plugin :remove_attachment
The plugin adds the #remove_<name>
accessor to your model, which removes the
attached file if it receives a truthy value:
photo.image #=> #<Shrine::UploadedFile>
photo.remove_image = 'true'
photo.image #=> nil
This allows you to add a checkbox form field for removing attachments:
form_for photo do |f|
# ...
f.check_box :remove_image
end
If you're using the Shrine::Attacher
directly, you can use the
Attacher#remove
accessor:
attacher.file #=> #<Shrine::UploadedFile>
attacher.remove = '1'
attacher.file #=> nil
