similar to: getting absolute paths on files on filesystem.

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

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 would imagine storing just the

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''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, I''ve been using InstantRails 1.0 that has ruby 1.8.4 and rails 1.0. Some of you might know that the RMagick package does not work with ruby 1.8.4. 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 have to use some API''s from some outside vendor to incorporate some of their video functionality, in particular, I have to somehow incorporate VideoEgg''s video publishing api''s.

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

Hi folks, I''m a linux noob, and I''m trying to pick a distro for my rails server. I don''t want to start a flame-war about linux distros! I''m interested in the best distribution for these criteria: 1 - Simplicity of getting ruby and rails set-up (gem updates) 2 - Stability (it is a server, after all) 3 - Support resources (community, and as a fall-back, paid

Hi I''m choosing a database for a new Rails application. I pretty much ruled out PostgreSQL, since despite good reviews of the database itself, it seems it has countless issues with Rails (for example: in recent releases migrations don''t work, and unit-tests fail). So I should now choose between MySQL 4.1, which as I understand enjoys widespread popularity - perhaps the most

Hello, I am attempting to create several plots based on "site" (~300 total) and am having trouble with the code. I simply want to create a plot using the code, plot(year, peak), for the following dataset. I would like for each site to be plotted on a separate page and the plots saved in a directory.
