Don’t simply test for the presence of the magic Paperclip attribute, it will return a paperclip Attachment object and thus always be true:
- if user.photo.present? # always true
= image_tag(user.photo.url)
Use #photo? instead:
- if user.photo?
= image_tag(user.photo.url)
just use the file_name column to check.
def thumbnail_path
thumbnail_file_name.present? ? thumbnail : nil
end
