file_column
Posted by Revolution
พอดีมีทำ upload ทั้งรูปและไฟล์ pdf ด้วย file_column แต่มีการกำหนดไว้ว่าให้ resize รูปที่ขึ้นไป พอ upload pdf ก็เกิดปัญหานะสิเพราะมัน resize ทำ thumbnail ไม่ได้ (ที่จริงก็ได้แต่ยังไงไม่รู้) เพราะมันจะทำให้ WebBrick crash ไป และก็ขี้เกียจไปสร้างอันใหม่

</notextile>ทำมันทั้งยังงี้ล่ะ เผื่อไฟล์อื่นจะได้ใช้ได้ด้วย ส่วน validates_file_format_of ก็เพื่มเอาเท่าที่ใช้
ไม่รู้ว่า act_as_attachment จะเป็นไงมั่ง แต่ตอนนี้สำหรับหผม file_column ยังโอเคอยู่
