问题描述
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的:
I have a file alert_import in lib/models/alert_import', I would like to use in my task sth like this:
task :send_automate_alerts => :environment do
# STDERR.puts "Path is #{$:}"
Rake.application.rake_require '../../lib/models/alert_import'
ai = AlertImport::Alert.new(2)
ai.send_email_with_notifcations
end
在这段代码中我得到错误:
In this code I get error:
找不到../../lib/models/alert_import
Can't find ../../lib/models/alert_import
在 AlertImport 我有:
in AlertImport I have:
module AlertImport
class Alert
def initialize(number_days)
@number_days = number_days
end
def get_all_alerts
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 import - status pending Last successful import was #{ last_successful_import ? last_successful_import.created_at : "never"}" if last_import.status == "pending"
else
alerts[o.id] = "There were no new files uploaded within #{@number_days} days"
end
else
alerts[o.id] = "The import was never triggered at all"
end
end
alerts
end
def send_email_with_notifcations
alerts =get_all_alerts
unless alerts.empty?
AlertMailer.email_notifications(alerts).deliver
end
end
end
end
正确的解决方法是:
desc "Send alerts about automate imports"
task :send_automate_alerts => :environment do
require "#{Rails.root}/lib/models/alert_import"
ai = AlertImport::Alert.new(2)
ai.send_email_with_notifcations
end
推荐答案
在 Rails 3.x 中,我通过首先使用 require
导入文件然后将模块包含到命名空间中取得了成功.这是它的外观:
In Rails 3.x, I've had success by first importing the file using require
and then including the module to the namespace. Here's how it would look:
require 'models/alert_import'
namespace :alerts
include AlertImport
desc 'Send alerts about automate imports'
task send_automate_alerts: :environment do
ai = AlertImport::Alert.new(2)
ai.send_email_with_notifcations
end
end
