how to check the database name that ActiveRecord uses

Question

In database.yml you define all the settings. How can I access those settings from ruby? I've looked in `App::Application::config`, but can't find it there. Also, I remember people were able to configure database settings without yaml, does anyone know how?

Accepted Answer

```
Rails.configuration.database_configuration
```

This will give you a hash table with the configurations for each of your environments. E.g. to get your development database name:

```
Rails.configuration.database_configuration["development"]["database"]
```
