Question

我制作简单的联系表格而没有任何花哨的宝石，我想我已经完成了，除了生产中没有任何作品。

我在rails 4.2.0 IDE中使用Cloud9。对于制作我使用Heroku和邮件Mailgun服务已在Heroku中启用。

当我尝试在开发环境中发送邮件时，我看到电子邮件是在服务器控制台中发送的，但是当我尝试在生产中执行时，它不会发送电子邮件，也不会将我重定向回到联系表单页面（在开发环境中）。也许我没有正确使用Mailgun，如果是这样，你能为邮件提供一些好的gmail教程，所以我可以在Heroku和Digital Ocean托管平台上使用它。

messages_controller.rb

class MessagesController < ApplicationController 

  def new
    @message = Message.new
  end

  def create
    @message = Message.new(message_params)

    if @message.valid?
      MessageMailer.message_me(@message).deliver_now
      redirect_to new_message_path, notice: "Thankyou for your message."
    else
      render :new
    end
  end

  private
    def message_params
      params.require(:message).permit(:name, :email, :subject, :content)
    end
end

message_mailer.rb

class MessageMailer < ApplicationMailer
  # use your own email address here
  default :to => "MYMAIL@gmail.com"

  def message_me(msg)
  @msg = msg

    mail(from: @msg.email, subject: @msg.subject, body: @msg.content)
  end
end

配置/环境/ production.rb

  config.action_mailer.delivery_method = :smtp
  config.action_mailer.smtp_settings = {
    :port           => ENV['587'],
    :address        => ENV['smtp.mailgun.org'],
    :user_name      => ENV['SANDBOX USERNAME GIVEN BY MAILGUN'],
    :password       => ENV['PASWORD'],
    :domain         => 'MYAPP.herokuapp.com', #eg: 'yourappname.herokuapp.com'
    :authentication => :plain,
  }

模型/ message.rb

class Message
  include ActiveModel::Model
  attr_accessor :name, :email, :subject, :content

  validates :name, :email, :subject, :content, presence: true
end

视图/消息/ new.html.erb

<%= form_for @message do |f| %>
  <% if @message.errors.any? %>
    <div id="error_explanation">
      <h2><%= "#{pluralize(@message.errors.count, "error")} prohibited this message from being sent:" %></h2>
      <ul>
        <% @message.errors.full_messages.each do |msg| %>
          <li><%= msg %></li>
        <% end %>
      <ul>
    </div>
  <% end %>

  <div class="field">
    <%= f.label :name %>
    <%= f.text_field :name %>
  </div>

  <div class="field">
    <%= f.label :email %>
    <%= f.email_field :email %>
  </div>

  <div class="field">
    <%= f.label :subject %>
    <%= f.text_field :subject %>
  </div>

  <div class="field">
    <%= f.label :content %>
    <%= f.text_area :content %>
  </div>

  <div class="actions">
    <%= f.submit 'Send', class: 'button' %>
  </div>
<% end %>

SMTP配置看起来不对。它应该从环境变量加载配置值，但您似乎试图将值放在那里：

config.action_mailer.smtp_settings = {
  :port           => ENV['587'],
  :address        => ENV['smtp.mailgun.org']
  :user_name      => ENV['SANDBOX USERNAME GIVEN BY MAILGUN'],
  :password       => ENV['PASWORD'],
  :domain         => 'MYAPP.herokuapp.com', #eg: 'yourappname.herokuapp.com'
  :authentication => :plain,
}

这应该设置为：

config.action_mailer.smtp_settings = {
  :port           => 587,
  :address        => 'smtp.mailgun.org'
  :user_name      => ENV['MAILGUN_USERNAME'],
  :password       => ENV['MAILGUN_PASSWORD'],
  :domain         => 'MYAPP.herokuapp.com', #eg: 'yourappname.herokuapp.com'
  :authentication => :plain,
}

然后，您需要在Cloud 9 Run面板中设置这些MAILGUN_USERNAME和MAILGUN_PASSWORD环境变量。
