Halt

Standard error handling for [ActionController][].

Installation

Add this line to your application’s Gemfile:

gem 'halt'

And then execute:

$ bundle

Or install it yourself as:

$ gem install halt

Usage

Include Halt in your ApplicationController, and use the halt macro
to rescue from exceptions.

class ApplicatioNController < ActionController::Base
  include Halt

  halt ActiveRecord::RecordNotFound, with: :not_found

Or, you can halt from within an action:

class PostsController < ApplicationController
  def create
    halt :unauthorized unless current_user.present?
    @post = Post.new post_params

    if @post.save
      redirect_to @post
    else
      render :new
    end
  end

  private

  def post_params
    params.require(:post).permit :title, :body
  end
end
