Creating a seo-friendly URL from a string

Question

Hi guys, I'm trying to create a url for a link from a string. Instead of example.com/Jessica Alba I want example.com/jessica-alba

How do I get link_to tags to link me to my friendly permalink?

I also need to make sure that the show method only displays the seo permalink in the address bar and only accepts the seo permalink.

It is best to use the parameterize method:

 name = name.parameterize

You can override the to_param method in your model.

So, if you have a model called Celebrity that has a name column, you 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)
