Controller Validations Lab

• Check the validity of a model in a controller
• Render a response with the error messages
• Use HTTP status codes to provide additional context

Question for teacher: In practice, will we use the rescue_from approach? Or the custom inline approach like

author = Author.new(author_params)
if author.save
  render json: author, status: :created
else
  render json: { errors: author.errors.full_messages }, status: :unprocessable_entity
end

or...both
