Convert Byte Array into HTML Image with Rails?

I have a Byte Array field being returned to me by the database, and in the view, I need to somehow output that as an image. How开发者_如何学JAVA would I do that in Rails?

Many thanks, M

You need send this byte by send_data helper.

You need you define another URL who send only this data_byte.
