Mein contact_spec.rb

end 

Mein contact.rb

class Contact < ActiveRecord::Base 
    has_many :phones 
    #accepts_nested_attributes_for :phones 

    validates :first_name, presence: true 
    validates :last_name, presence: ture 
    validates :email, presence: true, uniqueness: true 
    validates :phones, length: { is: 3 } 

    def name 
    [first_name, last_name].join('') 
    end 

    def self.by_letter(letter) 
    where("last_name LIKE ?", "#{letter}%").order(:last_name) 
    end 
end 

Wenn jemand mir helfen kann, werde ich schätzen!

In Ihrem contact.rb Sie haben einen Tippfehler

validates :last_name, presence: ture 

sein sollte

validates :last_name, presence: true
