Rails
1

Hi

I want to change the filename with File.rename but I get “Permission
denied” eve if I change the file with File.chmod(-777, “path/filename”)

I want to do this, to change the name of the image uploaded by
Paperclip.

If you have any sugestion or solution, write me.

Thanks.

File.chmod will presumably only work if your Ruby process is being
executed
by a user with the required permissions to run chmod in the first place;
I
suspect not in this case. Change the permissions on the directory with
your
files in so that user can access it, using the shell.

When changing a file’s name you need to have write permission on the
containing directory.

Hi

I changed the permissions of the directory from my command prompt (using
Windows). Used this command:

cacls path\folder /t /e /g Everyone:f

And I got the same message “Permission Denied”.

didn’t realize you were on a windows box - life can be somewhat less
rational there. unix has used the same permissions model and change
commands since it’s inception in 1970. calcs showed up sometime around
windows2000/xp and has now been depricated for use on windows7.

here’s a thread that you might find helpful;

you could save yourself much heartache (measured in decades) and build
yourself a linux box. microsoft does not make a software development
environment, they only make money.
