Instance Method Details

#http_error(code) ⇒ boolean (protected)

Returns the specified HTTP code in the action’s response, renders the correspondingly named HTML error document in public, and returns false. If a corresponding HTML error document doesn’t exist, you’ll probably get some sort of exception.

Examples:

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
