Rails Test "11" Add mail Send program and test mail send program

When it comes to testing the mail-sending program, we first want the system to send mail. Let's first add the ability to send mail to the system.

Action Mailer in Rails 3 is a good video tutorial that you can refer to.

There is a more detailed introduction of http://guides.rubyonrails.org/action_mailer_basics.html.

Add Mail Send Program

Send mail to ensure that we have the target mailbox, so our users have a property: email.

Or take my blog project as a practice project.

We send him an e-mail when the user registers.

First we create an initialization file

CONFIG/INITIALIZERS/SETUP_MAIL.RB, initializes the mailbox-related information.

Actionmailer::base.smtp_settings = { 
  : Address              => "smtp.163.com", 
  :p ort                 =>, 
  :d omain               => "163.com", 
  : User_name            => "woaiguanshui2012", 
  :p assword =>             "123456asdf", 
  : Authentication       => "plain", 
  : Enable_starttls_auto => True
}

We use 163 of the mailbox as a mail sending server, we need to have a registered user above, here I register a woaiguanshui201, the password is 123456ASDF.

Create a mail-sending program

Then create a mailer program with the Rails G Mailer command.

Rails G Mailer User_mailer

command creates a app/mailers/user_mailer.rb file.

Class Usermailer < actionmailer::base 
  default:from => "woaiguanshui2012@163.com"
End

Add a method inside to send a message to the user when they sign up.

Class Usermailer < actionmailer::base 
  default:from => "woaiguanshui2012@163.com"
  def registration_ Confirmation (user) 
    mail (: To => user.email,: Subject => "registered") 
  end 

Create a message content template

The content of the message can also be implemented through the template, and the controller action should have a view. Our Mailer method also needs a view to do the template.

Create the App/views/user_mailer/registration_confirmation.text.erb file, and write the following in the file.

Thank for registering!

Calling the mail-sending program

Up and down the last step, that is, after the user registered successfully, call this Mailer program Registration_confirmation method, you can send our predefined template file content.

We modify the user registration method, Userscontroller create method.

def create 
    @user = User.new (Params[:user]) 
     
    if @user. Save 
      usermailer.registration_confirmation (@user). Deliver 
     
      Flash[:notice] = "Sign Up successfully!"
      Signin (@user) 
      redirect_to root_path 
    else
      flash.now[:notice] = "Sign Up failed!"
      Render:new
    End 
  

Usermailer.registration_confirmation (@user). Deliver

The above line is our new addition, is the e-mail use.

This time to start our service Rails s, then register a user, and then look at the user's mailbox, you should have a letter from the woaiguanshui2012@163, the title is registered, the content is thank for registering!.

This means that our mail-sending programs are working properly.

Enrich Message Content Templates

We can also enrich the content of the message, such as adding user information. Modify the Registration_confirmation.text.erb file.

Hi, <%= @user. Nickname%> 
     
Thank for registering! 
     
Welcome to come back!

This requires us to add a returned variable @user to the Registration_comfirmation method.

def registration_confirmation (user) 
    @user = user 
   mail (: To => user.email,: Subject => "registered") 
 End
