ActiveRecord Validations Lab
Basic Validations
Add validations to these models such that...
- All authors have a name
- No two authors have the same name
- Author phone numbers are exactly ten digits
- All posts have a title
- Post content is at least 250 characters long
- Post summary is a maximum of 250 characters
- Post category is either
Fiction
orNon-Fiction
This step requires aninclusion
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.
