Rails Actionmailer发送多个收件人

Question

我无法让Rails立即向多个用户发送电子邮件.我正在尝试向与我们网站签名的多个场所发送通知,以便与其匹配的查询获得批准.

待定查询必须由管理员批准.邮件被传递@enquiry,即电子邮件被触发时.在我这里显示Enquiries controller:

def approve
    @enquiry.approve
    redirect_to [:admin, @enquiry], notice: 'Enquiry is approved.'
    SupplierMailer.new_enquiry(@enquiry).deliver
 end

在我Supplier_mailer.rb,我有这个方法:

    def new_enquiry(enquiry)
      @enquiry = enquiry
      @enquiry.venues.each do |venue|
        mail(to: venue.supplier.user.email, subject: 'You have a new enquiry')
      end
    end

目前,它只发送到1个电子邮件地址,因此不能正常循环.

楷模:

Enquiry 
  has_and_belongs_to_many :venues

Supplier
  has_many :venues
  has_one :user

我做错了什么？

谢谢

Answer 1

该new_enquiry方法应该构建一个电子邮件,然后通过deliver方法发送.循环正常工作,但每次调用邮件时,都会覆盖其先前的调用,并且该方法返回最后一次调用.

相反,首先获取收件人列表,并将其用作to属性

emails = @enquiry.venues.map {|venue| venue.supplier.user.email}
mail(to: emails, subject: 'You have a new enquiry')

如果您不喜欢彼此发送其他电子邮件,则需要在循环中放置Mailer操作:

def approve
  @enquiry.approve
  redirect_to [:admin, @enquiry], notice: 'Enquiry is approved.' 
  @enquiry.venues.each do |venue|
    SupplierMailer.new_enquiry(@enquiry, venue).deliver
  end
end

def new_enquiry(enquiry, venue)
  @enquiry = enquiry
  mail(to: venue.supplier.user.email, subject: 'You have a new enquiry')
end

最终选项非常hacky,但提供最佳界面:

class SupplierMailer << ActionMailer::Base

  def self.new_enquiry(enquiry)
    @enquiry = enquiry
    mails = @enquiry.venues.map do |venue|
      mail(to: venue.supplier.user.email, subject: 'You have a new enquiry')
    end
    class << mails
      def deliver
        each(&:deliver)
      end
    end
    mails
  end
