Basic knowledge of Ruby on Rails: You should have a basic understanding of Ruby on Rails and how it works. This includes knowledge of the MVC architecture, routing, and controllers.
A working Ruby on Rails application: You should have a working Ruby on Rails application that you can use to integrate Postmark. If you don't have an existing application, you can create a new one using the Rails command line tool.
A Postmark account: You will need to create a Postmark account to use their email service. Postmark offers a free trial account that you can use to follow along with the tutorial.
A text editor: You will need a text editor to edit your Rails application files. There are many text editors available, including Sublime Text, Atom, and Visual Studio Code.
Basic knowledge of HTML and CSS: You should have a basic understanding of HTML and CSS, as we will be using these languages to create email templates.
Basic knowledge of the command line: You should be comfortable using the command line to run Rails commands and install gems.
Ruby on Rails Postmark step by step setup and configuration
Integrating Postmark into a Ruby on Rails project is a straightforward process that involves configuring your application to use Postmark as your email service provider. To get started, you will need to create a Postmark account and obtain an API key. Once you have your API key, you can add the Postmark gem to your Rails application by adding the following line to your Gemfile:
After adding the Postmark gem to your Gemfile, run the following command to install it:
Next, you will need to configure your Rails application to use Postmark as your email service provider. To do this, create a new file called
postmark.rb in the
config/initializers directory and add the following code:
require 'postmark' Postmark.configure do |config| config.api_key = 'YOUR_API_KEY_HERE' end
YOUR_API_KEY_HERE with your actual API key. This code initializes the Postmark gem and sets your API key, allowing your Rails application to communicate with the Postmark API.
Once you have configured your Rails application to use Postmark, you can start sending transactional emails. To send an email, you can use the
deliver_now method provided by the Postmark gem. For example, to send a welcome email to a new user, you can add the following code to your controller:
def create @user = User.new(user_params) if @user.save UserMailer.welcome_email(@user).deliver_now redirect_to @user else render 'new' end end
This code creates a new user and sends a welcome email using the
deliver_now method provided by the Postmark gem. The
UserMailer class is responsible for creating the email message and formatting it using an HTML template.
