小编use*_*369的帖子

我在lib/models/alert_import'中有一个文件alert_import,我想在我的任务中使用......这样:

task :send_automate_alerts => :environment do

  ai.send_email_with_notifcations
end

在这段代码中我得到错误:

module AlertImport

  class Alert

    def initialize(number_days)

      alerts = { }
      Organization.automate_import.each do |o|
        last_import = o.import_histories.where(import_type: "automate").last
        last_successful_import = ImportHistory.last_automate_successful_import(o)
        if last_import
          if last_import.created_at + @number_days.days >= Time.now
            alerts[o.id] ="Error during last automate import Last successful import was #{ last_successful_import ? last_successful_import.created_at : "never"}" if last_import.status == "failure"
            alerts[o.id] ="Error during last automate …

你怎么杀死所有的heroku工人？

我试过了:

heroku scale worker=0

它不起作用.

我想将 activeadmin 过滤器与 hstore 一起使用：

在模型中，我有房间的柱设施。

我想做这样的事情：

过滤器 :amenities, :as => :select, :collection => proc {Room.all.map{|r| r.便利设施} }
