ActiveRecord Validations Lab

Basic Validations

Add validations to these models such that...

1. All authors have a name
2. No two authors have the same name
3. Author phone numbers are exactly ten digits
4. All posts have a title
5. Post content is at least 250 characters long
6. Post summary is a maximum of 250 characters
7. Post category is either Fiction or Non-Fiction This step requires an inclusion validator, which was not outlined in the README lesson. You'll need to refer to the [Rails guide][ar_validations] to look up how to use it. [ar_validations]: http://guides.rubyonrails.org/active_record_validations.html

Custom Validations

Finally, add a custom validator to Post that ensures the title is sufficiently clickbait-y. If the title does not contain "Won't Believe", "Secret", "Top [number]", or "Guess", the validator should return false.

For future projects, it's a good idea to skim the list of available validation options. It will give you a sense of what's available and help with creating validations for your own model objects.
