独立的活动记录：连接池

Question

Using activerecord outside rails, may I be confident all the connection drudgework is performed behind the curtains the same as inside rails?

In rails, activerecord does a great job establishing a connection pool and activating or closing connection as needed.

If I have a ruby daemon which calls a class file with:

ActiveRecord::Base.establish_connection(:production)
# more active_record tasks

can I assume on the following calls a connection from a pool is used?

Answer 1

是的，调用ActiveRecord::Base.establish_connection将根据ActiveRecord::Base.establish_connection内容创建连接池： https : //github.com/rails/rails/blob/master/activerecord/lib/active_record/connection_adapters/abstract/connection_pool.rb#L842
