Question

所以说我有两个使用database.yml文件连接的数据库，现在我希望我的sidekiq工作人员也连接到第二个数据库，但是当我从工作人员访问第二个数据库时，sidekiq工作人员最终会给ActiveRecord::NoDatabaseError: Unknown database

我的database.yml如下

development:
  adapter: mysql2
  database: database
  username: username
  password: password
  host: localhost

test:
  adapter: mysql2
  database: database
  username: username
  password: password
  host: localhost

production:
  adapter: mysql2
  database: database
  username: username
  password: password
  host: localhost

seconddatabase:
  development:
    adapter: mysql2
    database: database2
    username: username2
    password: password2
    host: different.localhost

  production:
    adapter: mysql2
    database: database2
    username: username2
    password: password2
    host: different.localhost

我的基本活动记录是

class SecondDatabaseBase < ActiveRecord::Base
  establish_connection configurations['seconddatabase'][ENV['RAILS_ENV']]
  self.abstract_class = true
end

我用来查询表的实际活动记录类是

class TableToQuery < SecondDatabaseBase
  self.table_name = 'table_to_query'
end

现在，当我运行以下查询时

TableToQuery.where(:column => 1)

它给我一个错误，说 ActiveRecord::NoDatabaseError: Unknown database 'seconddatabase'

Sidekiq如何访问Multipe活动记录数据库？
