altered_beast Data Model
If you have a look at db/schema.rb you'll see there are 12 tables.
- brain_busters
- forums
- moderatorships
- monitorships
- open_id_authentication_associations
- open_id_authentication_nonces
- open_id_authentication_settings
- posts
- schema_migrations
- sites
- topics
- users
Some, but not all, of these tables correspond to Models. JawSpeak: First Steps in Rails, RESTful by Example, Part 1: Beast has a diagram of the model used in the original Beast. This is still fairly appropriate for altered_beast although it should now include a Site model.
Most of the tables are created by the auto_migrations plugin from the initial db/schema.rb file. These tables include:
- forums
- moderatorships
- monitorships
- posts
- sites
- topics
- users
There are only three normal migrations:
- 001_create_permalinks.rb
- 002_add_brain_buster.rb
- 20090317123901_add_open_id_authentication_tables.rb
The first of these adds permalinks to three already existing tables: Forum, Topics and Users. The second only adds the brain_busters table for the brain_buster plugin. The third migration adds the three open_id_authentication tables.
The relations between Model, Table and Migrations are given in the following table.
| Model | Table | Table created by |
|---|---|---|
| brain_busters | migration 002 | |
| forum | forums | auto_migrations |
| moderatorship | moderatorships | auto_migrations |
| monitorship | monitorships | auto_migrations |
