海外TECH	DEV Community	Introduction of Rails Engine with basic example.	https://dev.to/harsh_u115/introduction-of-rails-engine-with-basic-example-2egm	Introduction of Rails Engine with basic example What is RailsEngine A Rails engine is a self contained piece of functionality that can be added to an existing Rails application or used as the foundation for a new Rails application Essentially it s a miniature Rails application that can be packaged and reused across multiple projects Rails engines provide a modular way to organize and reuse code in a Rails application They allow you to encapsulate related functionality such as authentication payments or notifications in a separate namespace with its own models views controllers routes and assets An engine can include all the same features as a regular Rails application including generators migrations tests and configuration options It can also have its own dependencies such as gems or other engines Rails engines are typically developed as separate gems that can be installed and managed using Bundler This makes it easy to share engines across multiple projects or with the wider community Rails engines are a powerful tool for building modular and reusable code in a Rails application and can help developers to build more maintainable and scalable applications They are used extensively in the Rails ecosystem and many popular gems such as Devise ActiveAdmin and Spree are implemented as engines Here are the steps to create a Rails engine with error handling Open your terminal and navigate to the directory where you want to create your engine Run the following command to create a new Rails engine rails plugin new my engine mountableThis will create a new directory called my engine with the basic structure of a Rails engine Open the my engine gemspec file and update the metadata to reflect the details of your engine such as its name version and description Open the lib my engine engine rb file and add any required dependencies or configuration options Create a sample method in lib my engine my engine rb that raises an error module MyEngine class MyEngine def self my method raise StandardError An error occurred in My Engine end endendCreate a sample controller in app controllers my engine my controller rb that calls the my method method module MyEngine class MyController lt ApplicationController def index begin MyEngine my method rescue StandardError gt e render plain Error e message end end endendThis controller defines an index action that calls the my method method and handles any exceptions that are raised Create a sample view in app views my engine my index html erb lt h gt Welcome to My Engine lt h gt lt p gt This is a sample view in My Engine lt p gt Update the config routes rb file to define a route for your engine MyEngine Engine routes draw do root to my index endFinally mount your engine into a Rails application by adding the following line to the config routes rb file mount MyEngine Engine at my engine That s it You ve now created a simple Rails engine with error handling When you navigate to the root path of your engine my engine you should see the error message that was raised by the my method method To call an engine method in a Rails application you can simply require the engine and call its methods as you would with any other Ruby class For example you could add the following code to a controller in your Rails application require my engine class MyController lt ApplicationController def index MyEngine MyEngine my method endendThis code requires the my engine gem and calls the my method method on the MyEngine class Any errors that are raised by the method will be handled by the controller s exception handling code as shown in the previous example Rails engines are a powerful tool for building modular and reusable code in a Rails application and can help developers to build more maintainable and scalable applications They can be used to encapsulate related functionality in a separate namespace or to develop standalone applications that can be mounted into a larger Rails application With error handling you can ensure that your engine provides robust and reliable functionality to its users Here s an example of how to create a Rails engine with notification and payment functionality Open your terminal and navigate to the directory where you want to create your engine Run the following command to create a new Rails engine rails plugin new my engine mountableThis will create a new directory called my engine with the basic structure of a Rails engine Open the my engine gemspec file and update the metadata to reflect the details of your engine such as its name version and description Open the lib my engine engine rb file and add any required dependencies or configuration options Create a Notification model in app models my engine notification rb module MyEngine class Notification lt ApplicationRecord validates message presence true enum status unread read endendThis model defines a Notification class with a message attribute and a status enum Create a Payment model in app models my engine payment rb module MyEngine class Payment lt ApplicationRecord validates amount presence true numericality true validates currency presence true inclusion in w USD EUR GBP enum status pending paid failed endendThis model defines a Payment class with an amount currency and status attribute Create a NotificationsController in app controllers my engine notifications controller rb module MyEngine class NotificationsController lt ApplicationController def index notifications Notification all end def mark as read notification Notification find params id notification update status read redirect to my engine notifications path end endendThis controller defines an index action that retrieves all notifications and a mark as read action that updates a notification s status to read Create a PaymentsController in app controllers my engine payments controller rb module MyEngine class PaymentsController lt ApplicationController def new payment Payment new end def create payment Payment new payment params if payment save redirect to my engine payments path notice Payment created successfully else render new end end private def payment params params require payment permit amount currency end endendThis controller defines a new action that creates a new payment and a create action that saves the payment to the database It also includes a payment params method to sanitize the payment parameters Create views for the NotificationsController in app views my engine notifications index html erb lt h gt Notifications lt h gt lt table gt lt thead gt lt tr gt lt th gt Message lt th gt lt th gt Status lt th gt lt th gt Actions lt th gt lt tr gt lt thead gt lt tbody gt lt notifications each do notification gt lt tr gt lt td gt lt notification message gt lt td gt lt td gt lt notification status capitalize gt lt td gt lt td gt lt link to Mark as Read my engine mark as read notification path notification method put gt lt td gt lt tr gt lt end gt lt tbody gt lt table gt mark as read html erb lt p gt Notification has been marked as read lt p gt lt link to Back to Notifications my engine notifications path gt Create views for the PaymentsController in app views my engine payments new html erb lt h gt New Payment lt h gt lt form with model payment url my engine payments path do f gt lt if payment errors any gt lt div id error explanation gt lt h gt lt pluralize payment errors count error gt prohibited this payment from being saved lt h gt lt ul gt lt payment errors full messages each do message gt lt li gt lt message gt lt li gt lt end gt lt ul gt lt div gt lt end gt lt div gt lt f label amount gt lt f text field amount gt lt div gt lt div gt lt f label currency gt lt f select currency options for select USD USD EUR EUR GBP GBP gt lt div gt lt div gt lt f submit Create Payment gt lt div gt lt end gt index html erb lt h gt Payments lt h gt lt flash each do type message gt lt div class lt type gt gt lt message gt lt div gt lt end gt lt table gt lt thead gt lt tr gt lt th gt Amount lt th gt lt th gt Currency lt th gt lt th gt Status lt th gt lt tr gt lt thead gt lt tbody gt lt payments each do payment gt lt tr gt lt td gt lt payment amount gt lt td gt lt td gt lt payment currency gt lt td gt lt td gt lt payment status capitalize gt lt td gt lt tr gt lt end gt lt tbody gt lt table gt lt link to New Payment my engine new payment path gt Finally add routes for the NotificationsController and PaymentsController in config routes rb Rails application routes draw do mount MyEngine Engine gt my engine namespace my engine do resources notifications do put mark as read on member end resources payments only new create index endendThis will mount the engine at the my engine URL and define routes for the NotificationsController and PaymentsController With these steps you now have a functional Rails engine with notification and payment functionality To call these engine methods in a Rails app you can mount the engine in the config routes rb file of your app and use the generated engine routes to access the engine s controllers and models For example Rails application routes draw do mount MyEngine Engine gt my engine get notifications to my engine notifications index post notifications mark as read id to my engine notifications mark as read as mark as read notification get payments new to my engine payments new post payments to my engine payments create get payments to my engine payments index endThis will allow you to access the notifications and payments functionality provided by the engine in your Rails app by visiting the appropriate URLs For example you can create a link to the MyEngine notifications page using the following code in one of your views lt link to My Notifications my engine notifications path gt This will create a link to the notifications index page provided by the engine which you can style and modify as desired to fit your app s design To call the notification and payment functionality provided by the Rails engine in a Rails application you can use the routes and helper methods generated by the engine Here s an example of how you could use these helper methods in a view to display a list of notifications and a link to the payment page lt app views my app index html erb gt lt h gt Welcome to My App lt h gt lt h gt Notifications lt h gt lt ul gt lt MyEngine Notification all each do notification gt lt li gt lt notification message gt lt unless notification read gt lt link to Mark as read mark as read notification path notification gt lt end gt lt li gt lt end gt lt ul gt lt h gt Payments lt h gt lt link to Make a payment my engine payments path gt In this example we re using the MyEngine Notification model provided by the engine to display a list of notifications along with a link to mark each notification as read We re also using the mark as read notification path helper method provided by the engine to generate the appropriate URL for marking a notification as read Finally we re using the my engine payments path helper method provided by the engine to generate a link to the payment page When the user clicks this link they ll be taken to the payment page provided by the engine where they can make a payment using the payment functionality provided by the engine Overall integrating a Rails engine into a Rails application is similar to using any other external library or gem in a Rails app By using the routes and helper methods provided by the engine you can easily access the functionality provided by the engine and integrate it into your application as
