我在多租戶應用程序上使用rails 3和paperclip。我試圖根據Photo.current_account的值設置圖像的路徑,但它似乎不起作用。但是,當我把它放在rename_image中時,它就可以工作。什麼可能是錯的?我對此進行了設置,以便在用戶上傳時,目標將基於該請求期間用戶的子域。 Photo.current_account已經擁有控制器的子域信息。無法使用以下設置自定義回形針路徑:url
http://subdomain1.lvh.me:3000/system//photos/images/000/000/708/original/1417662848.jpg?1417662848
目前,輸出就像上面的行一樣,你可以在系統/它的空白字符串之後看到。
