所以我在codermanual上做了一个在线训练营，顺便说一句，我是一个初学者，刚开始学习Ruby和其他webdev的东西。
我坚持某一步，而且我有一个关于＆＃34;接收电子邮件的问题＆＃34;从我的webapp的联系表单页面通过heroku。
出于某种原因，我似乎无法使sendgrid工作。 当我点击联系表单的提交按钮时，网页会返回错误消息。
我精确地遵循了这些步骤，但我的contacts_controller.rb似乎有问题，特别是这行代码：
ContactMailer.contact_email（姓名，电子邮件，正文）.deliver
ruby v2.3.0p0
$ heroku logs
ArgumentError（发送邮件需要SMTP地址。设置消息smtp_envelope_to，to，cc或bcc地址。）： 2016-06-13T05：24：00.381485 + 00:00 app [web.1]：app / controllers / contacts_controller.rb：14：在'create＆＃39;
感谢帮助。 以下是其余文件：
class ContactsController < ApplicationController
def new
@contact = Contact.new
end
def create
@contact = Contact.new(contact_params)
if @contact.save
name = params[:contact][:name]
email = params[:contact][:email]
body = params[:contact][:comments]
ContactMailer.contact_email(name, email, body).deliver
flash[:success] = 'Message sent.'
redirect_to new_contact_path
else
flash[:danger] = 'Error occured, message has not been sent'
redirect_to new_contact_path
end
end
private
def contact_params
params.require(:contact).permit(:name, :email, :comments)
end
end
