Friendly URLs

By default, Rails applications build URLs based on the primary key -- the id column from the database. Imagine we have a Person model and associated controller. We have a person record for Bob Martin that has id number 6. The URL for his show page would be:

/people/6

But, for aesthetic or SEO purposes, we want Bob's name in the URL. The last segment, the 6 here, is called the "slug". Let's look at a few ways to implement better slugs.

        location /resize {
                alias /tmp/nginx/resize;
                set $width 150;
                set $height 100;
                set $dimens "";

                if ($uri ~* "^/resize_(\d+)x(\d+)/(.*)" ) {
                        set $width  $1;
                        set $height $2;
                        set $image_path $3;

# app/views/posts/new.html.erb

<%= form_for(Post.new) do |form| %>
  Title: <%= form.text_field :title %>
  Body:  <%= form.text_field :body %>
<% end %>

...would produce a signature field that can be used to automatically untaint:

  <input type="hidden" name="signature" value="....">

Installing rbx-2.0.0-dev with Ruby 1.9 support using rbenv can be a tad tricky. This is what I did to get up and running, you'll need another version of ruby already installed as well as rake.

The basic outline:

1. Clone Rubinius HEAD from github
2. Configure installation for rbenv and 1.9 support
3. Install Rubinius
4. Configure your $PATH to use Rubinius gems
5. Start using Rubinius
