Whats::Wrong

Overriding Rails default static error pages for your locale.

Add this line to your application's Gemfile:

gem 'whats-wrong'

rails g whats_wrong:pages zh-CN
# Creating pages for zh-CN ...
#       create  public/404.zh-CN.html
#       create  public/422.zh-CN.html
#       create  public/500.zh-CN.html

Supported locales: en, zh-CN.

Maybe static pages couldn't fit your necessary. Enable this feature If you want to render error pages with layout.

rails g whats_wrong:install

Then the default error pages will be rendered within your layout.

Also you can custom error pages(include 404, 422 and 500).

<!-- app/views/exceptions/404.html.erb -->
<p>The page you were looking for doesn't exist.</p>


<!-- some helper methods you can use -->
<p><%= status %></p> <!-- 404 or others -->
<p><%= original_path %></p> <!-- which path case error before render error page -->
<p><%= exception %></p><!-- which exception case error -->
