我有一个rake任务，可以发送出去的电子邮件通知，如何对它们进行分组

Question

我有一个rake任务，它根据我的条目表发送电子邮件通知：

如果approve_disapprove的值为“ 3”（3表示“待定”），它将向批准该条目的人发送电子邮件，表明该条目仍在等待处理。

问题是，如果有多个条目，它将通过并为approve_disapprove查找带有3的每个条目，并为每个条目发送一封电子邮件。

因此，如果我有5个条目，然后当我的任务在第二天完成并看到它们仍标记为3时，它将向批准者发送5封电子邮件。

如何将其分组，以便根据我在条目表中称为section的另一列将它们全部分组。 如果它对所有条目进行了分块或分组（带有3个待处理条目），并按部门名称分组，那么它只会向该部门的经理发送一封电子邮件，其中包含所有5个请求？

这是我的具有check_pending任务的输入模型

def self.check_pending # What this does is goes through each entry and looks at approve_disapprove if its a 3 which is pending it will sent an alert to the employees manager. 
  check_pending = Entry.where(approve_disapprove: 3)                      
  check_pending.each do |entry|
      EntryMailer.check_pending(entry).deliver
  end
end

这是我的待审核支票邮件

class EntryMailer < ActionMailer::Base

  def check_pending(entry)
    @entry = entry

    mail to: @entry.emp_mail_addr, subject: '(TEST) You have pending time off requests that require approval or disapproval'
  end
end

这是我的check_pending邮件视图

Hello

#{@entry.mgr_name}


 The following time off request are pending please approve or disapprove once you have made your decision.


 %li
  %span.u= @entry.emp_first_name
  %span.u= @entry.emp_last_name
 %li Dept
 %li= @entry.emp_dept
 %li Leave Start
 %li= @entry.leave_start.strftime('%m/%d/%y')
 %li Leave End
 %li= @entry.leave_end.strftime('%m/%d/%y')
 %li Type Of Request
 %li= @entry.indirect_id

这是耙任务

 desc "Looks at pending request if the are still marked pending sends a email to the manager for the request"
 task :check_pending => :environment do
   Rails.logger.info "Check Pending: Finding all pending."
   Entry.check_pending
   Rails.logger.info "Found Pending: Check complete."
   Rails.logger.flush
 end

额外信息

    t.datetime "created_at"
    t.datetime "updated_at"

    t.string   "emp_no"

Answer 1

这里的问题是您需要入口对象来获取有关入口的信息，因此您必须重新编写视图的逻辑。

首先，在您的Entry模型中定义几个范围：

class Entry < ActiveRecord::Base #I'm assuming AR here
  scope :pending, -> { where(approve_disapprove: 3) }
  scope :for_section, ->(section) { where(section: section) }
end

然后将您的rake任务更改为按部分分组并传递一个关系，而不是一个条目：

def self.check_pending 
  sections = Entry.pending.pluck(:section).uniq                     
  sections.each do |section|
      entries = Entry.pending.for_section(section)
      EntryMailer.check_pending(entries).deliver
  end
end

然后，您需要修改邮件程序：

class EntryMailer < ActionMailer::Base

  def check_pending(entries)
    @entries = entries
    emails = @entries.map(&:emp_mail_addr).uniq.join(',') #may not need this if your email will always be the same, could just grab the first @entries.first.enp_addr
    mail to: emails, subject: '(TEST) You have pending time off requests that require approval or disapproval'
  end
end

最后，您的视图将需要遍历以下内容：

Hello

#{@entries.first.mgr_name}


 The following time off request are pending please approve or disapprove once you have made your decision.

- @entries.each do |entry|

  %li
    %span.u= entry.emp_first_name #note change from @entry to entry
    ...
