ruby on rails - Creating seo friendly url from a string -


hey guys i'm trying create url friendly link string. instead of example.com/jessica alba, want example.com/jessica-alba

how link_to tags link me seo friendly permalink?

i need make sure show method displays seo friendly permalink in address bar , accepts seo friendly permalink.

you can override to_param method in model.

so if have model called celebrity, has name column can go:

class celebrity < activerecord::base    def to_param     self.name.downcase.gsub(' ', '-')   end  end

then:

  jessica_alba = celebrity.find_by_name("jessica alba")   link_to "jessica alba", celebrity_path(jessica_alba)
