Overview

Railtie to hook Keycard into Rails applications.

This does three things at present:

1. Loads our rake tasks, so you can run keycard:migrate from the app.
2. Pulls the Rails database information off of the ActiveRecord
   connection and puts it on Keycard::DB.config before any application
   initializers are run.
3. Sets up the Keycard database connection after application
   initializers have run, if it has not already been done and we are not
   running as a Rake task. This condition is key because when we are in
   rails server or console, we want to initialize!, but when we are in
   a rake task to update the database, we have to let it connect, but
   not initialize.

.after_initializers(&block) ⇒ Object

Register a callback to run after anything in ‘config/initializers’ runs. The block will get a reference to Keycard::DB.config as its only parameter. Keycard::DB.initialize! will not have been automatically called at this point, so this is an opportunity to do so if an initializer has not.

.when_keycard_is_ready(&block) ⇒ Object

Register a callback to run when Keycard is ready and fully initialized. This will happen once in production, and on each request in development. If you need to do something once in development, you can choose between keeping a flag or using the after_initializers.
