How to Use Multiple Databases in a Rails App Using the database.yml

Question

I\'ve read up on the documentation on how to do this, but in practice, I am having problems. In my app, I have 2 different databases as described below in my database.yml file.

Answer 1

I tried to replicate and got it to work. It has to do with naming conventions: You're in development mode and AR will look for the development tag, which in your case does not exist for sqlite.

Here is my database.yml:

development:
  adapter: mysql2
  database: se_development
  username: root
  pool: 5
  timeout: 5000

sqlite_development:
  adapter: sqlite3
  database: db/development.sqlite3
  pool: 5
  timeout: 5000

Here is the model:

class Plot < ActiveRecord::Base
  establish_connection 'sqlite_' + Rails.env
end

Worked for me. Hope this helps.
