Question

我正在开发一个使用RoR和Sendgrid发送批量电子邮件的Web应用程序。使用未定义的方法`to_model'为 NoMethodError ：0xa6e7980您的意思是？ to_yaml

发送和发送电子邮件但出现此错误。作为rails和ruby的新手，我迷失了，似乎无法弄清楚即使在上网了近6个小时之后该怎么做才能消除这个错误。我的代码如下：
1. test_mailer.rb

class TestMailer < ApplicationMailer
    include SendGrid
    sendgrid_enable   :ganalytics, :opentrack
    default from: 'abc@company.com'

    def send_email(e_arr, s_arr)
        @e_arr = e_arr
        @s_arr = s_arr
        headers['X-SMTPAPI'] = { :to => @e_arr }.to_json
        mail(
            :to => "this.is@ignored.com",
            :subject => "Hello User",
        ).deliver
    end
end

2。的routes.rb

    Rails.application.routes.draw do
        root 'static_pages#home'
        get  'static_pages/home'
        post 'static_pages/home', to: 'static_pages#func'
    end

3.static_pages_controller.rb

    class StaticPagesController < ApplicationController
      skip_before_action :verify_authenticity_token
      def home 
      end
      def func
          postvar = params[:Emails];
          lines = postvar.split("\n");
          arr = [];
          lines.each {|line|
              arr.push(line.split("@")[0]);
          }
          redirect_to TestMailer.send_email(lines, arr)
      end
    end

4。的environment.rb

# Load the Rails application.
require_relative 'application'

# Initialize the Rails application.
Rails.application.initialize!

ActionMailer::Base.smtp_settings = {
  :address => "smtp.sendgrid.net",
  :port => 25,
  :domain => "abc.com",
  :authentication => :plain,
  :user_name => "xyz",
  :password => "pqr"
}

Answer 1

您不能redirect_to邮件程序send_mail功能。

而不是

redirect_to TestMailer.send_email(lines, arr)

只做

TestMailer.send_email(lines, arr).deliver_now

在另一行中redirect_to发送邮件后要转到的路径，或呈现所需的视图，或者如果func只是来自现有操作的方法调用，则不要执行任何操作，并且它会回到行动。

用于＃<actionmailer :: messagedelivery：0xa6e7980>的未定义方法`to_model'
