Implementing Mandrill Email

gistfile1.txt

Pre-Work:

Got to Mandrill and set up and account. Have your `username` and `keys` ready.

In Rails, run ` rails g mailer NotificationsMailer` (or something similar) will set up a new file in the `app/mailer/` folder. In this case it generates a `notifications_mailer.rb`. It also creates a new dir: `app/views/notifications` 

1. Configure your Mail APP .  In `config/application.rb`  add the following configuration :  

```
    config.action_mailer.delivery_method = :smtp

    config.action_mailer.smtp_settings = {
      address: 'smtp.mandrillapp.com',
      port: 587,
      domain: 'example.com',
      user_name: ENV[mandrill_username],
      password: ENV[mandrill_password],
      authentication: 'plain',
      enable_starttls_auto: true
    }
```

2. Set up the controller actions!
In the NotificationsController :

```
class NotificationsController < ApplicationController
  def show
  end

  def create
    NotificationsMailer.contact(email_params).deliver_now

    redirect_to :back, notice: "Your Email was Sent"
  end

  private

  def email_params
    params.permit(:name, :email, :message)
  end
end
```

3. Add the contact method in your class!
In notificaitons_mailer.rb
```
class NotificationsMailer < ApplicationMailer
  def contact(email_params)
    @message = email_params[:message]

    mail(
      to: email_params[:email],
      subject: "Message for #{email_params[:name]}"
    )
  end
end
```

Also, add this to your `ApplicationMailer` class:
```
class ApplicationMailer < ActionMailer::Base
  default from: "from@example.com"
  layout 'mailer'
end
```

You'll now need to create two templates. You can simply render `@message` in your email views.

1. `app/views/notifications_mailer.contact.html.erb`
2. `app/views/notifications_mailer.contact.text.erb`

At this point, your email should work(send)
