Forum: Rails Spinoffs (closed, excessive spam) Help with gsub

Ok I will admit I suck at making regex patterns.

I want to transform the value to be all lowercase, _ instead of
spaces, and no special chars. (Basically a websafe filename). Here is
what I have. It works all except stripping out special chars.

Any help would be great.

    v = v.toLowerCase();
    v = v.gsub(' ', '_');
    v = v.gsub('/[^a-z0-9\s]/i', '');

v = v.gsub(/[^a-z0-9\s]/i, '');

v = v.gsub(/[^a-z0-9\s]/i, '');

Thanks!
