Rails 如何将电子邮件表单与 Sendgrid 链接？

Question

我能够创建一个联系表单，当用户单击提交时，它会发送一封电子邮件，我会在我的收件箱中收到该表单。我想通过 sendgrid 发送该电子邮件，以便我可以分析分析。我查看了 Gorails Sendgrid 课程，并能够通过 sendgrid 发送电子邮件，但我不知道如何将其应用于我的联系表。我在下面列出了我的代码，任何帮助都会很棒。非常感谢！

new.html.erb（当用户点击提交时定期发送电子邮件的联系表）

<div align="center">
<h3>Send A message to Us</h3>
  <%= form_for @contact do |f| %>
<div class="field">
    <%= f.label :name %><br>
    <%= f.text_field :name, :required => true %>
</div>
<div class="field">
    <%= f.label :email %><br>
    <%= f.email_field :email, :required => true %>
    </div>
    <div class="field">
    <%= f.label :message %><br>
    <%= f.text_area :message, :as => :text, :required => true %>    
</div>
<div class="actions">
    <%= f.submit "Send Message", :class => "btn btn-primary btn-md"%>
    </div>
  <% end %>
</div>

contacts_controller.rb

class ContactsController < ApplicationController
  def new
@contact = Contact.new
  end
  def create
@contact = Contact.new(contact_params) 
@contact.request = request
if @contact.deliver
  flash.now[:notice] = 'Thank you for your message. We will contact you soon!'
else
  flash.now[:error] = 'Cannot send message.'
  render :new
end
  end
  private
  def contact_params
  params.require(:contact).permit(:name, :email, :message)
  end
end

Sendgrid.rb（在我的配置 > 初始化程序文件夹中）

ActionMailer::Base.smtp_settings = {
  :user_name => 'apikey',
  :password => Rails.application.secrets.sendgrid_api_key,
  :domain => 'tango.co',
  :address => 'smtp.sendgrid.net',
  :port => 587,
  :authentication => :plain,
  :enable_starttls_auto => true
}

development.rb

config.action_mailer.perform_caching = false
config.action_mailer.delivery_method = :smtp
ActionMailer::Base.smtp_settings = {
:user_name => 'apikey',
:password => Rails.application.secrets.sendgrid_api_key,
:domain => 'tango.co',
:address => 'smtp.sendgrid.net',
:port => 587,
:authentication => :plain,
:enable_starttls_auto => true
}

邮件文件夹（我只有两个文件通知和应用程序都没有处理我的联系人表单）

我知道我缺少什么。我需要为联系人生成邮件。完成并在我的contacts_controller.rb中添加一行后，我就可以毫无问题地通过sendgrid发送我的电子邮件了:)

class ContactsController < ApplicationController  
def new
@contact = Contact.new
  end
  def create
@contact = Contact.new(contact_params) 
@contact.request = request
if @contact.save
    ContactMailer.new_request(@contact.id).deliver_later
end
if @contact.deliver
  flash.now[:notice] = 'Thank you for your message. We will contact you soon!'
else
  flash.now[:error] = 'Cannot send message.'
  render :new
end
  end
  private
  def contact_params 
   params.require(:contact).permit(:name, :email, :message)
 end
end

联系邮寄者

class ContactMailer < ApplicationMailer 
 def new_request
 end
end
