Rails 4, the production asset pipeline no longer generates filenames without cache-busters. This means that referencing /assets/application.css in your static public/404.html page won’t work in a Rails 4 app! The file will not exist in the production environment. The only way to reliably reference your application stylesheet is to use the stylesheet_link_taghelper. But error pages are static HTML pages; they can’t use helpers, right? 404 error page design If you want nice-looking error pages in Rails 4, here are youroptions: Option 1: No external styles. Don’t reference your application stylesheet at all. Instead, use simple, static error pages with the necessary minimal CSS copied and pasted into each HTML file. This is the solution that ships withRails. Works for simple apps that don’t need custom-branded errorpages. Option 2: Monkey patch. Use static error pages and point to /assets/application.css for styling. Then, monkey-patch Rails to restore the pre-Rails 4 behavior so that the asset pipeline generates non-cache-busted filenames in production. Make sure not to send far-future expires headers for thesefiles! Easiest option for migrating an existing app to Rails4. Option 3: Dynamic. Use dynamic view templates (ERB) for error pages, and take advantage of the stylesheet_link_tag helper to get the right cache-busted filename. Error pages can use your application styles. Be careful, though: if your Rails app is down, your error pages can’t beaccessed. Most flexible option. This is the solution I describebelow. OK, so you’re ready to set up dynamic error pages in a Rails 4 app? Here’s how to doit. 1 Generate an errors controller andviews rail

They reveal it.” Apparently that’s a twist on the original quote from John Wooden, a Hall of Fame basketball player and coach, who was referencing sports rather than hard times. Nevertheless, I love the quote, and it does apply to many more things in life beyond sports. In fact, I think it even applies to websites as well. One of the situational hard times websites face is when they earn a coveted organic link (especially from an authoritative source!), but then the linking webmaster makes an error in the URL. If the error is in the domain name, well, tough noogies. But if the webmaster gets the domain name right but blows it on the folder or file name, what users of the linking site see when they click that link to your site can make or break their first experience with you. Does your site reveal the wise character of forethought to users who click broken links or mistype URLs, or has that opportunity been squandered? Put another way, do you have a custom 404 error message page in place? A custom 404 error message page prevents web browsers from otherwise showing a stark, empty, generic white page rudely stating “404 – File Not Found”. As user experiences go, this is pretty much rock bottom. This is the mother of all bounce-inducing events. Create a custom 404 page Creating, posting and configuring your web server to use a basic 404 error message page is easy, and I’m going to show you how. But first I do have a couple of caveats that I have to address before I go on: Typically most custom 404 error pages are static pages that are used for site-wide 404 errors, and that is what I’m going to cover in this post. However, there are technology options available that enable webmasters to implement dynamic 404 error pages. However, that’s more of a developer-based topic, and frankly, this is not a developer column. Since the vast majority of we
