如何在Ruby On Rails中发送多个电子邮件

Question

我想在单个请求中向多个用户发送电子邮件。我有一个成员表，其中包含员工ID，但该成员表没有电子邮件列。员工表有电子邮件列。所以当我发送请求并选择成员时，所有选定的成员都应该收到电子邮件。

def issue_tracker_group_email(issue_request)
  @issue_request = issue_request
  @issue_request = IssueRequest.find(issue_request.id)
  @issue_tracker_group = IssueTrackerGroup.find(issue_request.issue_tracker_group_id)
  mail(to: @issue_tracker_group.email, subject: 'Issue Request')
end

Answer 1

你可以这样做：

    def issue_tracker_group_email(issue_request)
      @issue_request = issue_request
      @issue_request = IssueRequest.find(issue_request.id)
      @issue_tracker_group = IssueTrackerGroup.find(issue_request.issue_tracker_group_id)
      @email=@issue_tracker_group.map{|i| i.email}.join(",")
      mail(to:@email, subject: 'Issue Request')
    end
