HTTP Error for Rails

This Rails plugin makes an http_error method available in ApplicationController which

• returns the specified HTTP code in the response,
• renders the correspondingly named HTML error document in public, and
• returns false.

Returning false allows you to use http_error in before_filter’s to halt the filter chain.

Full documentation is at RubyDoc.info.

Example

The following will return a 404 HTTP code, render public/404.html, and halt the filter chain so that @user.destroy! is never executed.

class UserController < ApplicationController
  before_filter(:get_user)

  def delete
    @user.destroy
  end

  protected

  def get_user
    @user = User.find_by_id(params[:id])
    http_error(404) unless @user
  end
end
