轨道邮件与不同的布局 [英] rails mailer with different layouts

问题描述

我在通知器模型（20多个电子邮件）中为我的所有电子邮件使用一个布局...但是有时我只想发送一个没有布局或HTML的纯文本电子邮件。我似乎无法弄清楚怎么样？如果我尝试发送一个纯文本电子邮件，我仍然会得到电子邮件中的所有HTML。

我使用的是Rails 2.3.8。 >

我在这里阅读了这个猴子补丁，但似乎表明一个较新版本的rails已经过来了？如果我可以避免一个麻烦，我真的不想要猴子补丁。

Rails - 为邮件模板的多部分电子邮件设置多个布局

  layoutemail＃use email.text。（html | plain）.erb作为布局
 
 
 def welcome_email（property）
主题'新注册'
收件人property.email 
 from'[e-mail]'
 body：property =>属性
 content_typetext / html
 end 
 
 def send_inquiry（询问）
主题＃{inquire.the_subject}
收件人查询.email 
来自Test代表＃{inquire.name}<＃{inquire.email}> 
 body：inquire =>查询
 content_typetext / plain
 
 end 
  

也有2个档案。

  email.text.html.erb 
 email.text.plain.erb 
  

它始终使用text.html.erb ...即使content_type是text / plain

解决方案

编辑：对于电子邮件模板，布局遵循不同的命名方案。只需重命名它们如下：

  layout.text.html.erb => layout.html.erb 
 layout.text.plain.erb => layout.text.erb 
  

如果您使用这一点，我也犯了手动定义部件的错误：

  part：content_type => 'text / plain'，
：body => render_message（'my_template'）
  

然后Rails无法确定你的部分的content_type，它假定它是HTML。

当我改变了这两件事情，它为我工作！

过去很多次，我一直在努力解决这个问题，通常会以某种非干燥的速度和肮脏解。我一直认为我是唯一有这个问题的人，因为Google对这个问题没有任何有用的东西。

这一次我决定挖掘Rails来计算出来到目前为止没有太多的成功，但也许我的发现将帮助别人了解这一点。

我发现是在ActionMailer ::基础#render_message方法被任务确定适当的content_type，并将其分配给@current_template_content_type。 #default_template_format然后为布局返回正确的mime类型，或者如果@current_template_content_type未设置，则默认为：html。

这是ActionMailer :: base＃render_message看起来像我的应用程序（2.3.5）

  def render_message（method_name，body）
如果method_name .respond_to？（：content_type）
 @current_template_content_type = method_name.content_type 
 end 
 render：file => method_name，：body =>身体
确保
 @current_template_content_type = nil 
 end 
  

麻烦是method_name看起来是一个字符串（本地视图的名称，在我的例子中是new_password.text.html），字符串当然不会回覆到#content_type，意味着@current_template_content_type将始终保持为零，所以#default_template_format将始终默认为：html。

我不知道更接近实际的解决方案。 ActionMailer内部对我来说太不透明。

I use one layout for all my emails in my Notifier model (20+ emails)... however sometimes I just want to send a plain text email with no layout or html at all. I can't seem to be able to figure out how? If I try to send a plain text email i still get the layout, and all the HTML in the email.

I'm using Rails 2.3.8.

I read about this monkey patch here... but it seemed to indicate a newer version of rails had over come this? And I don't really wanna monkey patch if I can avoid one.

Rails - setting multiple layouts for a multipart email with mailer templates

  layout "email" # use email.text.(html|plain).erb as the layout


  def welcome_email(property)
    subject    'New Signup'
    recipients property.email
    from       '[e-mail]'
    body       :property => property
    content_type "text/html"
  end

  def send_inquiry(inquire)
    subject    "#{inquire.the_subject}"
    recipients inquire.ob.email
    from       "Test on behalf of #{inquire.name} <#{inquire.email}>"
    body       :inquire => inquire
    content_type "text/plain"

  end

I also have 2 files.

email.text.html.erb
email.text.plain.erb

It always uses text.html.erb... even if the content_type is "text/plain"

解决方案

edit: Figured it out, the layouts follow a different naming scheme to the email templates. Just rename them as follows:

layout.text.html.erb    => layout.html.erb
layout.text.plain.erb   => layout.text.erb

I also made the mistake of manually defining the parts, if you use this:

part :content_type => 'text/plain',
     :body => render_message('my_template')

Then Rails can't determine the content_type for your part and it assumes it's HTML.

After I changed those two things it worked for me!

I've struggled with this question many times in the past, usually ending up with some sort of non-dry quick and dirty solution. I always thought I was the only one with this problem because Google turns up exactly nothing useful on the subject.

This time I decided to dig into Rails to figure it out but so far without much success, but maybe my findings will help someone else figure this out.

What I found was that in ActionMailer::Base the #render_message method is tasked with determining the proper content_type and should assign it to @current_template_content_type. #default_template_format then either returns the proper mime type for the layout or, if @current_template_content_type isn't set, it will default to :html.

This is what ActionMailer::Base#render_message looks like in my app (2.3.5)

  def render_message(method_name, body)
    if method_name.respond_to?(:content_type)
      @current_template_content_type = method_name.content_type
    end
    render :file => method_name, :body => body
  ensure
    @current_template_content_type = nil
  end

The trouble is that method_name appears to be a string (the name of the local view, in my case "new_password.text.html") and strings of course do not respond_to #content_type, meaning @current_template_content_type will always remain nil, and so the #default_template_format will always default to :html.

Not much closer to an actual solution, I know. The ActionMailer internals are just too opaque for me.
