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.

# Asserting a link based on HREF

Then /^(?:|I )should see a link to (.+?)(?: with the text "([^\"]*)")?(?: within "([^\"]*)")?$/ do |page_name, text, selector|
  with_scope(selector) do
    page.should have_css("a[href='#{ path_to(page_name) }']", :text => text)
  end
end

Then /^(?:|I )should see a mailto link for "([^\"]*)"(?: with the text "([^\"]*)")?(?: within "([^\"]*)")?$/ do |email_address, text, selector|
  with_scope(selector) do
