I tried this at console and got the following.

```ruby
Person.model_name
# => #<ActiveModel::Name:0x00000103143850 @name="Person", @klass=Person, @singular="person", @plural="people", @element="person", @human="Person", @collection="people", @param_key="person", @i18n_key=:person, @route_key="people", @singular_route_key="person"> 
```
