Question

I have a Rails app and a Sinatra app, sharing the same database. The Sinatra app uses ActiveRecord.

Can I run migrations from within each app, as if they were in the same app? Will this cause any problems?

The schema.rb file in the Rails app tracks the current migration via

ActiveRecord::Schema.define(:version => 20121108154656) do

but, how does the Sinatra app know the current version the database?

Rails 3.2.2, Ruby 1.9.3.

Answer 1

I decided to put all migrations in the Rails app because:

1. Since there is only one database
2. Rails manages migrations

This has worked well.

This simplifies the system because all migrations are stored in one place. And, the Sinatra app doesn’t need to know about them anyway.
