如何使Rails模型根据环境类型有条件地建立连接

Question

I have a rails model that looks like this:

class Db_Prod_Write < ActiveRecord::Base
    establish_connection :prod_write 
    self.abstract_class = true
end

:prod_write is a production environment defined in my database.yaml file.

This model (Db_Prod_Write) is being used in another model in a method that establishes a connection. The problem is, that when the method is running in QA environment, it still runs the method in production. Is there a way for me to make establish_connection :prod_write in the above code conditional so that it only establishes if the environment is production?

Thank you in advance.

Answer 1

establish_connection(:prod_write) if Rails.env.production?

Answer 2

测试以下任何一项：

• ENV['RAILS_ENV']
• RAILS_ENV
• Rails.env
• Rails.env.production?
