问题描述
我正在关注StackOverflow帖子中引用的有关简单联系表单的教程。教程在此处:
I'm following a tutorial referenced in a StackOverflow post for a simple contact form. Tutorial is here: http://matharvard.ca/posts/2011/aug/22/contact-form-in-rails-3/
一切都是复制/粘贴并更改我的域的一些值和邮件设置。遇到两个非常奇怪的错误:当我第一次提交联系表单时,我得到一个:
Everything is copy/paste and change a few values for my domain and mail settings. Running into two very strange errors: When I first submit the contact form, I get a :
Rails.root:/ Users / me / application
Rails.root: /Users/me/application
应用程序跟踪|框架跟踪完全跟踪
Application Trace | Framework Trace | Full Trace
加载以下文件时发生此错误:
This error occurred while loading the following files:
mail / parsers / rfc2822_obsolete
mail/parsers/rfc2822_obsolete
如果我重新提交而不重新启动Rails应用程序,则会得到:
If I resubmit without restarting the rails app, I get:
Rails.root:/ Users / me / application
Rails.root: /Users/me/application
应用程序跟踪|框架跟踪完整跟踪
Application Trace | Framework Trace | Full Trace
app / mailers / notifications_mailer.rb:1:in`'
app/mailers/notifications_mailer.rb:1:in `'
app / controllers / contact_controller .rb:11:in'create'
app/controllers/contact_controller.rb:11:in `create'
此错误在加载以下文件时发生:
This error occurred while loading the following files:
我认为可能涉及的部分是:
The sections I feel might be relavent are:
class NotificationsMailer < ActionMailer::Base
default :from => "[email protected]"
default :to => "[email protected]"
def new_message(message)
@message = message
mail(:subject => "mydomain Feedback")
end
end
class Message
include ActiveModel::Validations
include ActiveModel::Conversion
extend ActiveModel::Naming
attr_accessor :name, :email, :subject, :body
validates :name, :email, :subject, :body, :presence => true
validates :email, :format => { :with => %r{.+@.+\..+} }, :allow_blank => true
def initialize(attributes = {})
attributes.each do |name, value|
send("#{name}=", value)
end
end
def persisted?
false
end
end
class ContactController < ApplicationController
def new
@message = Message.new
end
def create
@message = Message.new(params[:message])
if @message.valid?
NotificationsMailer.deliver_new_message params[:message]
# NotificationsMailer.new_message(@message).deliver
redirect_to(root_path, :notice => "Message was successfully sent.")
else
flash.now.alert = "Please fill all fields."
render :new
end
end
end
其余的模板非常简单并且可以很好地呈现。
The rest of the templates are very straightforward and rendering fine.
此外,附加gemfile以防万一我错过了一些明显的冲突:
Also, attaching the gemfile in case I missed some obvious conflict in there:
source 'https://rubygems.org'
gem 'rails', '3.2.8'
gem 'sqlite3'
gem 'redis', '2.1.1'
group :assets do
gem 'sass-rails', '~> 3.2.3'
gem 'coffee-rails', '~> 3.2.1'
gem 'uglifier', '>= 1.0.3'
end
gem 'jquery-rails'
gem 'jade'
gem "haml", ">= 3.1.7"
gem "haml-rails", ">= 0.3.5", :group => :development
gem "hpricot", ">= 0.8.6", :group => :development

谢谢。
推荐答案
I认为ContactController.rb中的以下代码是罪魁祸首:
I think the following code from ContactController.rb is the culprit:
NotificationsMailer.deliver_new_message params[:message]
您实际上没有方法名称deliver_new_message
You do not actually have a method name deliver_new_message
尝试将其删除,并取消注释下面的行:
Try removing it, and uncommenting the line below it:
NotificationsMailer.new_message(@message).deliver
希望这会有所帮助
这篇关于Rails 3.2.8 Actionmailer-堆栈级别太深,加上未初始化的常量Mail :: Ruby19的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持!
