Establish a connection to another database only in a block?

Question

In a rails application, I have this code in pure ruby :

class LinkCreator
  attr_accessor :animal

  def initialize(animal:)
    @animal = animal
  end

  de         


        

Answer 1

It would be nice if you keep all database connections in database.yml

development:
  adapter: mysql2
  other stuff...
  
db_2:
  adapter: mysql2
  other stuff..

other_envs:
.....

Then create a class

class OtherDB < ActiveRecord::Base
  establish_connection(:db_2)
end

From your controller you can access just like

OtherDB.table_name = "table_name"
OtherDB.first
