Custom error pages

Current workaround: patch Site#http:

I'm guessing there's no way to customize the Kansas message?

Read above : )

Fixed in evaryont/toto@32b4d9ba75c0bfb99bcc2a60e24f618bfb929fde

To use it, just add set :error_page lambda { |code| "lol you got an error (#{code})" } to your config.ru

[ariejan]

Nice! But can it display a custom page instead?

[nogweii]

Not as easily as you may like, though you can use the go() method, so I think (this is just off the top of my head) go "/error/#{code}.html" should work, if you want to use static pages.

Of course, you can use go in any manner, redirecting to any (local) URL.

I get the following when I try to use go "/error/404" (which I can navigate to directly, so I know my page works):

NoMethodError at /2010/04/01/this-is-a-test4
undefined method 'go' for #<Toto::Config:0x10172a6f8>

This is now official, and the setting is just called :error

For custom pages, you could probably just load the file with File.read("public/#{code}.html") or something similar..

How could we render the 404 page with existing layout?

[ariejan]

Try this (I'm using HAML):

set :error do |code|
  ::Haml::Engine.new(File.read("templates/pages/#{code}.haml"), :layout => 'layout', :format => :html5, :ugly => true).render("templates/layout")
end

[samnang]

ariejan, how about using ERB?

[ariejan]

@samnang - I don't use ERB, but it could be something like this:

ERB.new(File.read("templates/pages/layout.rhtml")).result(File.read("templates/pages/#{code}.rhtml"))

[samnang]

@ariejan, I got an error because I have to pass binding object to ERB#result method instead of string.

The easiest way is to:

  # ...
  set :error, lambda {|code|
    ERB.new(File.read("templates/pages/error-#{code}.rhtml")).result
  }
  # ...
