TestMailer 的参数数量错误
我在发送电子邮件时遇到了一个奇怪的问题。 我遇到了这个异常:
ArgumentError (wrong number of arguments (1 for 0)):
/usr/lib/ruby/gems/1.8/gems/activerecord-2.1.1/lib/active_record/base.rb:642:in `initialize'
/usr/lib/ruby/gems/1.8/gems/activerecord-2.1.1/lib/active_record/base.rb:642:in `new'
/usr/lib/ruby/gems/1.8/gems/activerecord-2.1.1/lib/active_record/base.rb:642:in `create'
/usr/lib/ruby/gems/1.8/gems/ar_mailer-1.3.1/lib/action_mailer/ar_mailer.rb:92:in `perform_delivery_activerecord'
/usr/lib/ruby/gems/1.8/gems/ar_mailer-1.3.1/lib/action_mailer/ar_mailer.rb:91:in `each'
/usr/lib/ruby/gems/1.8/gems/ar_mailer-1.3.1/lib/action_mailer/ar_mailer.rb:91:in `perform_delivery_activerecord'
/usr/lib/ruby/gems/1.8/gems/actionmailer-2.1.1/lib/action_mailer/base.rb:508:in `__send__'
/usr/lib/ruby/gems/1.8/gems/actionmailer-2.1.1/lib/action_mailer/base.rb:508:in `deliver!'
/usr/lib/ruby/gems/1.8/gems/actionmailer-2.1.1/lib/action_mailer/base.rb:383:in `method_missing'
/app/controllers/web_reservations_controller.rb:29:in `test_email'
在我的 web_reservations_controller 中,我有一个简单的方法调用
TestMailer.deliver_send_email
我的 TesMailer 类似于:
class TestMailer < ActionMailer::ARMailer
def send_email
@recipients = "[email protected]"
@from = "[email protected]"
@subject = "TEST MAIL SUBJECT"
@body = "<br>TEST MAIL MESSAGE"
@content_type = "text/html"
end
end
你有什么想法吗?
谢谢! 罗伯托
I'm running a strange problem sending emails. I'm getting this exception:
ArgumentError (wrong number of arguments (1 for 0)):
/usr/lib/ruby/gems/1.8/gems/activerecord-2.1.1/lib/active_record/base.rb:642:in `initialize'

/app/controllers/web_reservations_controller.rb:29:in `test_email'
In my web_reservations_controller I have a simply method calling
TestMailer.deliver_send_email
And my TesMailer is something like:
class TestMailer < ActionMailer::ARMailer
def send_email
@recipients = "[email protected]"
@from = "[email protected]"
@subject = "TEST MAIL SUBJECT"
@body = "<br>TEST MAIL MESSAGE"
@content_type = "text/html"
end
end
Do you have any idea?
Thanks!
Roberto

问题在于 ar_mailer 用于存储消息的模型。 您可以在回溯中看到异常来自 ActiveRecord::Base.create 当它调用初始化时。 通常,ActiveRecord 构造函数需要一个参数,但在本例中,您的模型似乎没有。 ar_mailer 应该使用名为“电子邮件”的模型。 你的 app/models 目录中有这个类吗? 如果是这样,初始化是否会覆盖任何内容? 如果您要覆盖初始化,请务必为其提供参数并调用 super。
The problem is with the model that ar_mailer is using to store the message. You can see in the backtrace that the exception is coming from ActiveRecord::Base.create when it calls initialize. Normally an ActiveRecord constructor takes an argument, but in this case it looks like your model doesn't. ar_mailer should be using a model called Email. Do you have this class in your app/models directory? If so, is anything overridden with initialize? If you are overriding initialize, be sure to give it arguments and call super.
检查 email_class 设置是否正确: http://seattlerb.rubyforge.org /ar_mailer/classes/ActionMailer/ARMMailer.html#M000002
也不要使用实例变量。 尝试:
从文档中: body 方法有特殊的行为。 它采用一个散列,该散列生成一个以散列中的每个键命名的实例变量,其中包含该键所指向的值。
因此,在上面的方法中添加了这样的内容:
将允许您在模板中使用
@user
。Check that email_class is set correctly: http://seattlerb.rubyforge.org/ar_mailer/classes/ActionMailer/ARMailer.html#M000002
Also don't use instance variables. Try:
From the docs: the body method has special behavior. It takes a hash which generates an instance variable named after each key in the hash containing the value that that key points to.
So something like this added to the method above:
Will allow you to use
@user
in the template.
