Hi, I''m able to upload files onto my webserver filesystem but I had a question regarding how I''d go about accessing them using the <img src="..." > tag. If my files, i.e pictures, are being uploaded to public/images/<dir>/filename.jpg, then should I store the entire path, or just the picture name in my database table?

I''m now trying to downgrade to ruby 1.8.2 within my InstantRails 1.0 install. Is there a clean way of doing this? I basically downloaded ruby 1.8.2 and replaced the ruby directory with the newly created ruby directory. As

Hi, I''m using InstantRails 1.0 (rails 1.0 and ruby 1.8.4). When I try to upload a video file ~11MB, IE just hangs on me. Seems like WEBrick hangs too and I can''t connect from another IE.

Hello, My question has to do with a form resubmit problem. Say for example a form is submitted and within that form, a picture is uploaded. If the user presses the Back buttom and gets back to the form submission sheet, and then clicks on resubmit, once again, the same data is populated into my tables wasting space (another picture upload for no reason in a separate row). Now, I know there are

I've attached a less-hackish implementation of this. This includes the following modifications: - getSupportsOverlappingAliases() method on TargetMachine which returns whether the target supports multiple symbols to the same object.
