getting "undefined method 'validates'" error after validating format video.

Try changing "validates" to "validate" in your code and let us know if you still have problems.

That did not work either. Here is my code so far...

class User < ActiveRecord::Base # Include default devise modules. Others available are: # :token_authenticatable, :confirmable, # :lockable, :timeoutable and :omniauthable devise :database_authenticatable, :registerable, :recoverable, :rememberable, :trackable, :validatable

# Setup accessible (or protected) attributes for your model attr_accessible :email, :password, :password_confirmation, :remember_me, :first_name, :last_name, :profile_name

Validate :first_name, presence: true

Validate :last_name, presence: true

Validate :profile_name, presence: true, uniqueness: true, format: { with: /a-zA-Z0-9_-/, message: 'Must be formatted correctly.' }

has_many :statuses

def full_name first_name + " " + last_name end
end

Try chaning "Validate" to "validate" with the first letter lower cased and let us know how it works out.

Yes, that worked! Thank you for your help!
