我一直在使用带有Rails的Mongoid Adapter作为应用程序。所以我基本上把项目设置为不使用ActiveRecord(因为我也将它部署到Heroku)。我遵循了一个教程,它对我有用:
Remove database adapter gems from your Gemfile, e.g., mysql2, sqlite3, etc
From application.rb, remove require 'rails/all' and add
require "action_controller/railtie"
require "action_mailer/railtie"
require "sprockets/railtie"
require "rails/test_unit/railtie"
Delete database.yml, schema.rb and all the migrations
Delete migration checks from test/test_helper.rb
Delete all activerecord related configuration from config/environments
但是,现在 - 当我在我的网络应用程序(导入csv进程)中优化进程时,我决定使用ActiveJob + Resque来使用延迟作业。
据我所知,我需要Redis for Resque,所以我安装了它并运行了服务器,但是Resque的rake任务设置如下:
require 'resque/tasks'
task "resque:setup" => :environment do
Resque.before_fork = Proc.new do |job|
ActiveRecord::Base.connection.disconnect!
end
Resque.after_fork = Proc.new do |job|
ActiveRecord::Base.establish_connection
end
end
似乎需要ActiveRecord来完成它的工作(当然因为它映射到redis数据库)。当我跑这个时毫不奇怪:
LOGGING=1 QUEUE=* bundle exec rake resque:work
它会发出错误(因为缺少ActiveRecord):
*** Failed to start worker : #<NameError: uninitialized constant ActiveRecord>
如何使这项工作?
答案 0 :(得分:0)
我知道这是前一段时间被问到的,但这里的答案是你可以安全地删除前/后工作程序与你自己的resque.rake
这是我的:
#lib/tasks/resque.rake
require 'resque/tasks'
require 'resque/scheduler/tasks'
namespace :resque do
task setup: :setup_logger do #setup logger includes environment!
require 'resque'
require 'resque-scheduler'
end
end
#Sets up logging - should only be called from other rake tasks
task setup_logger: :environment do
logger = Logger.new(STDOUT)
logger.level = Logger.const_get((ENV["LOG_LEVEL"] || "DEBUG").upcase)
Rails.logger = logger
end
