Rails 3.1:

describe "cats/edit" do
  before(:each) do
    @cat = assign(:cat, stub_model(Cat,
      :name => "MyString"
    ))
  end

  it "renders the edit cat form" do

        # Doubly unfortunate: hax to support Mocha's hax.

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.

  # Based on https://gist.github.com/1182136
  class BootstrapLinkRenderer < ::WillPaginate::ActionView::LinkRenderer
    protected

    def html_container(html)
      tag :div, tag(:ul, html), container_attributes
    end

    def page_number(page)
      tag :li, link(page, page, :rel => rel_value(page)), :class => ('active' if page == current_page)
