Question

使用Whenever gem设置计划的rake任务。需要切换到特定架构（在我的项目中使用Apartment gem）

config / schedule.rb中的代码

env :PATH, ENV['PATH']
env :GEM_PATH, ENV['GEM_PATH']
set :output, "#{Whenever.path}/log/scheduler.log"
every 1.minute do
  rake "db:my_task"
end

lib / tasks / my_task.rake中的代码

namespace :db do
  task :my_task => :environment do
    Apartment::Tenant.switch("subdomain") do
       #My Code here
    end
  end
end

在log log / scheduler.logs

中生成以下错误

  rake aborted!

你缺少ActiveRecord :: Base.establish_connection.connection试试这个示例代码如下：

print(eval('a' + '.' + b + '(target)'))  # >>> 3

desc＆＃39;更新数据＆＃39;

任务email_normalize_to_downcase ::环境 create_connection_with_db ！公寓:: Tenant.switch（＆＃39;应用＆＃39）

namespace :debtor_email_data_fix do

端

任务全部：[：email_normalize_to_downcase]做端

私有

def create_connection_with_db 的ActiveRecord :: Base.establish_connection.connection 结束端

Rails租户模式切换，后台作业无效
