Hi, I''m calling a helper I''ve written - format_time() that is called from my views with a given time that was selected from my database and was returned to the view via an instance variable.

Hi, I have one minor issue. I''m trying to check whether a directory is empty given some path to the directory. My code does the following: if(File.directory?(dirpath)) # dirpath = public/images/1 if(File.zero?(dirpath)) FileUtils.rm_rf(dirpath) end end The problem is, while testing this, if I put a file in the directory and run the above code, it still ends up deleting the

As you might know, LFTP is a popular FTP/SFTP command-line client for most systems. One feature that is lacking from this tool is the ability to do a globbed ls via sftp. I have a patch ready for LFTP that incorporates some of the knowledge [like oddball systems glob() handling] and some of the code from sftp-glob.c for this tool to add this capability. I do, however, have some questions about

Hi, How do I pass a variable from my action into a model before saving the model. I''d like the model instance to have access to this variable to do some work before saving the model instance but the variable is not part of the model itself. Thanks, Sam -- Posted via http://www.ruby-forum.com/.

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
