我有一個rake任務，可以發送出去的電子郵件通知，如何對它們進行分組

Question

我有一個rake任務，它根據我的條目表發送電子郵件通知：

如果approve_disapprove的值為“ 3”（3表示“待定”），它將向批准該條目的人發送電子郵件，表明該條目仍在等待處理。

問題是，如果有多個條目，它將通過並為approve_disapprove查找帶有3的每個條目，並為每個條目發送一封電子郵件。

因此，如果我有5個條目，然后當我的任務在第二天完成並看到它們仍標記為3時，它將向批准者發送5封電子郵件。

如何將其分組，以便根據我在條目表中稱為section的另一列將它們全部分組。 如果它對所有條目進行了分塊或分組（帶有3個待處理條目），並按部門名稱分組，那么它只會向該部門的經理發送一封電子郵件，其中包含所有5個請求？

這是我的具有check_pending任務的輸入模型

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

這是我的待審核支票郵件

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

這是我的check_pending郵件視圖

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

這是耙任務

 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

額外信息

條目表列

  table "entries"
    t.datetime "created_at"
    t.datetime "updated_at"
    t.string   "emp_id"
    t.string   "emp_no"
    t.string   "emp_first_name"
    t.string   "emp_last_name"
    t.string   "emp_mail_addr"

    t.string   "mgr_first_name"
    t.string   "mgr_last_name"
    t.string   "mgr_mail_addr"
    t.datetime "leave_start"
    t.string   "employee_type"
    t.integer  "seq_no",           
    t.decimal  "range_days",        
    t.string   "alt_mgr_no"
    t.string   "alt_mgr_name"
    t.string   "alt_mgr_addr"
    t.string   "emp_dept"
    t.datetime "leave_end"
    t.string   "approve_disapprove"
    t.string   "section"

Answer 1

這里的問題是您需要入口對象來獲取有關入口的信息，因此您必須重新編寫視圖的邏輯。

首先，在您的Entry模型中定義幾個范圍：

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

然后將您的rake任務更改為按部分分組並傳遞一個關系，而不是一個條目：

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，您需要修改郵件程序：

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，您的視圖將需要遍歷以下內容：

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
    ...
