render_optional_error_file(status_code) — ActionController::Rescue

render_optional_error_file(status_code)

Attempts to render a static error page based on the status_code thrown, or just return headers if no such file exists. At first, it will try to render a localized static page. For example, if a 500 error is being handled Rails and locale is :da, it will first attempt to render the file at public/500.da.html then attempt to render public/500.html. If none of them exist, the body of the response will be left empty.

Parameters

status_code req
