Rails - Mar 2006 - String manipulation

I need to make some nicenames from my post titles, like:
- convert spaces to "-"
- delete all the !,?,commas,.,;.:,* from the string

How can I do? Sorry for the noob question...

Oh, and another thing... How can I make permalink this way:
Not .../blog/show/4 but .../category/nicename ?


Thankyou.

Lookup the gsub! method in the String documentation.  (Look in the
Ruby docs, not the Rails docs.)

you should have a look at the typo code (typo.leetsoft.com). Imho it
solves both issues you mentioned.

Hi Dan,

  Try something like:
  
  delete all the characters: (Add, or modify characters as needed)
  
 
link=@article[:title].gsub(/([''*&^%$+_))((**&&^%$\#@\!~`{}\/\.\,\;])/,
'''' )
  
  create permalink:
  
  [root@srv31 ror]# ruby script/console
  Loading development environment.
  str=>> str="My long string"
  => "My long string"
  >>   def create_permalink(string)
  >>     string.gsub(/([^ a-zA-Z0-9_.-]+)/n) do
  ?>       ''%'' + $1.unpack(''H2'' *
$1.size).join(''%'').upcase
  >>      end.tr('' '', ''-'').downcase
  >>
  ?>   end
  => nil
  >> permalink=create_permalink(str)
  => "my-long-string"
  >>
  
  Modify to your preferences.

  Try something like this in routes.rb
  
  map.connect ''category/:link'', :controller =>
"blog", :action => ''show''
  
  Hope this helps.
