我们正在使用Ruby 1.9和Rails 3.2我们将AS / 400用于我们的数据库。我们之前尝试过使用Active Record，因为我们的Ruby和Rails版本较旧，并且需要将它与400连接，所以它不想工作。
我们有一个在线订购网站，您必须设置一个帐户才能访问。根据您设置的帐户类型，您可能必须由某人批准您的订单。即如果我是一个下落账户，我的经销商必须批准我订购的东西。它的设置方式，经销商没有得到任何类型的批准电子邮件。
我们一直在控制台中尝试下面的代码，让它运行起来。如果我们输入帐号而不是将其留空，则会返回将收到批准电子邮件的电子邮件地址列表。太棒了！如果它如下所示留空，则返回一个空白数组。有道理，我们还没有登录，所以它还不知道我们的帐号。当用户登录时，他们的帐号应自动替换为。
Contact.find_by_sql ["SELECT EMAL23 FROM WEBOEL23 WHERE ACT223 = ‘’”]
但是，当我们将该代码段添加到order.rb文件中时，它会返回错误：
wrong number of arguments (1 for 4)
显然，我们设置线路的方式并不正确：
Mailer.deliver_order_distributor_approval_email('Contact.find_by_sql (SELECT EMAL23 FROM WEBOEL23 WHERE ACT223 = "30153"')
它只是让人感到困惑......我们似乎与错误一起走了一圈。我们尝试修复它，但接下来我们只是得到了与该行有关的新错误。

如果order.rb文件有用，我可以附上它...它只是有点冗长，所以我没有把它包含在帖子中。如果您对如何更改mailer.deliver_order_distributor_approval_email行有任何建议，请告诉我们。我真的很感激！提前谢谢！
修改
Mailer.deliver_order_distributor_approval_email ('Contact.find_by_sql SELECT EMAL23 FROM WEBOEL23 WHERE ACT223 = "30153"'),"Coastal Pet Online Ordering<noreply@coastalpet.com>", "Order Confirmation-customer", email_details
有了这个（在经过一些调整之后），我们能够毫无错误地提交订单，但我们没有收到任何电子邮件。奇。看起来我们可能会错过一些邮件或其他东西吗？
修改 在修改了脚本建议之后，我们想出了这个......
target_email = Contact.find_by_sql ["SELECT EMAL23 FROM WEBOEL23 WHERE ACT223 = ''"]
Mailer.deliver_order_confirmation_email(target_email, "Coastal Pet Online Ordering<noreply@coastalpet.com>", "Order Confirmation-customer", email_details)
它＆＃34;工作＆＃34;没有错误 - 我们可以登录并提交订单，但仍然无法收到任何电子邮件。 奇怪的是，当通过控制台运行时，该片段会返回以下错误。
ActiveRecord::StatementInvalid: 37000 (-10) [IBM][iSeries Access ODBC Driver][DB 2 UDB]SQL0010 - String constant beginning ' ' not delimited.
如果我们输入如下的帐号，它会运行并提交..但仍然没有电子邮件。它也会在控制台上返回错误。
target_email = Contact.find_by_sql ["SELECT EMAL23 FROM WEBOEL23 WHERE ACT223 ='30153'"]
Mailer.deliver_order_confirmation_email(target_email, "Coastal Pet Online Ordering<noreply@coastalpet.com>", "Order Confirmation-customer", email_details)
错误：
NameError: undefined local variable or method `email_details' for main:Object
想法？
答案 0 :(得分：0)
您收到的错误消息：
wrong number of arguments (1 for 4)
表示您调用了一个需要四个参数的方法，但是您只提供了一个参数。这是您的方法调用：
Mailer.deliver_order_distributor_approval_email('Contact.find_by_sql (SELECT EMAL23 FROM WEBOEL23 WHERE ACT223 = "30153"')
如上所述，您提供了一个参数：字符串'Contact.find_by_sql (SELECT EMAL23 FROM WEBOEL23 WHERE ACT223 = "30153"'。
当您调用方法Mailer.deliver_order_distributor_approval_email时，它最终会将给定的参数传递给您在order_distributor_approval_email类中定义的Mailer方法。该方法需要四个参数，但你只给它一个，因此错误。您需要提供所有四个参数才能使方法调用起作用。
<强>更新
您正在传递字符串'Contact.find_by_sql SELECT EMAL23 FROM WEBOEL23 WHERE ACT223 = "30153"'作为第一个参数，因此邮件程序正在尝试将该字符串视为电子邮件地址，这自然不起作用。大概你想在find_by_sql上实际调用Contact方法来获取真实的电子邮件地址，在这种情况下你会想要这样的东西：
target_email = Contact.find_by_sql('SELECT EMAL23 FROM WEBOEL23 WHERE ACT223 = "30153"').first
Mailer.deliver_order_distributor_approval_email(target_email, "Coastal Pet Online Ordering<noreply@coastalpet.com>", "Order Confirmation-customer", email_details)
这应执行查询并尝试将电子邮件发送到第一个结果。您需要进一步调整以发送给多个收件人或发送多封电子邮件。
