[RUBY] 11.2 Send Account Activation Email: Rails Tutorial Notes--Chapter 11

11.2 Send account activation email

11.2.1 Outgoing email template

You can generate mailers with rails generate (Password_reset will be used later)

$ rails generate mailer UserMailer account_activation password_reset 

The product is below

      create  app/mailers/user_mailer.rb #Define something like an action here
      invoke  erb
      create    app/views/user_mailer
      create    app/views/user_mailer/account_activation.text.erb #Email layout (text)
      create    app/views/user_mailer/account_activation.html.erb #Email layout (html)

ERB can be used for layout

edit_account_activation_url(@user.activation_token, email: @user.email)

And take two arguments Returns a path like the following

/account_activations/(1st argument)/edit?(2nd argument)

The following are called ** query parameters ** Written as a key / value pair with ? Email = ...

Make the view file embed the above url helper

** Instance variables **, ** Destination **, ** Title ** used in view files Define in app / mailers / user_mailer.rb`

  def account_activation(user)
    @user = user
    mail to: user.email, subject: "Account activation"

11.2.2 Preview of outgoing email

If you follow the procedure You will be able to preview in your browser

11.2.3 Testing Outgoing Email

The test is already described below Cause of $ rails test> (RED)

require 'test_helper'

class UserMailerTest < ActionMailer::TestCase
  test "account_activation" do
    mail = UserMailer.account_activation
    assert_equal "Account activation", mail.subject
    assert_equal ["[email protected]"], mail.to
    assert_equal ["[email protected]"], mail.from
    assert_match "Hi", mail.body.encoded


Rails.application.configure do
  config.action_mailer.delivery_method = :test
  config.action_mailer.default_url_options = { host: 'example.com' } #Set up a test environment host

It should be $ rails test> (GREEN)

    assert_equal ["[email protected]"], mail.from

After fixing

It became $ rails test> (GREEN)

11.2.4 Updated user create action

Change create action

--Send mail with ʻUserMailer.account_activation (@user)` --Change flash message --Do not log in at this point --Change redirect destination

	def create
    @user = User.new(user_params)
    if @user.save
      flash[:info] = "Please check your email to activate your account."
      redirect_to root_url
      render 'new'

Since the behavior changes, it becomes $ rails test> (RED)
