Answer 1

Ich denke, wenn es Rollback ist, ist das Problem von Ihrer Validierung. unten ist Beispielcode-Format für validates_attachment, die wahrscheinlich können Sie

has_attached_file :image 
validates_attachment :image, :content_type => { :content_type => ["application/octet-stream","image/jpg","image/jpeg","image/png"] }
