In a Ruby on Rails project, all migration files generate into the same directory 'db/migrate'. It's enough for simple projects, but not that good for large modulized projects. It is inconvenient to review thousands of files in the same directory for one project.
It looks like:

Since MVC directories are modular, the migration directory should the same. It's expected to be structured and clear. That's the reason I release the gem <a href="https://github.com/swordray/modular_migration">modular\_migration</a>\.
Just include it in your Gemfile:
<code>gem 'modular_migration'</code>
Using Rails generator as usual:
<code>$ rails generate model Core::User name:string invoke active_record create app/models/core/user.rb create app/models/core.rb create db/migrate/core/user/20140324105328_create_core_users.rb </code>
It will look like:
