- ### Problem
It's no longer possible to define a numeric validation on abstract
class:
```ruby
class AnimalsBase < ApplicationRecord
self.abstract_class = true
validates :age, numericality: { min: 18 }
end
class Dog < AnimalsBase
end
Dog.create!(age: 0) => ActiveRecord::TableNotSpecified: Dog has no table configured. Set one with Dog.table_name=
```
### Solution
Instead of trying to get the type for attribute on the class
defining the validation, get it from the record being validated.
