I have one database (call it "First") with 4 tables. And I Have another database (call this database "Second"), (with another password). I want take emails (field) from Second and table if there are any updates was and inserting into First database.
Question: How I can do it?
You can define different databases in your database.yml.
first:
adapter: mysql
database: first_development
username: user
password: pwd
host: localhost
second:
adapter: mysql
database: second_development
username: user
password: pwd
host: localhost
and then connect your models to different databases using ActiveRecord::Base.establish_connection
class A < ActiveRecord::Base
ActiveRecord::Base.establish_connection "first"
end
class B < ActiveRecord::Base
ActiveRecord::Base.establish_connection "second"
def self.sync
A.all.each do |record|
B.create(:email => record.email)
end
end
end
I added a simple method called sync that can be a starting point for your synchronisation issue,
