Ich bekomme den obigen Fehler, aber verstehe nicht warum. Hier ist der Stack-Trace:NoMethodError: undefinierte Methode `validates_confirmation_of 'Sinatra

     from /Users/benrumble/.rvm/gems/ruby-2.3.0/bin/ruby_executable_hooks:15:in `<main>'

und hier ist das user.rb Modell

require 'bcrypt' 
require 'dm-validations' 

class User 
    attr_reader :password 
    attr_accessor :password_confirmation 

    validates_confirmation_of :password 

    include DataMapper::Resource 

    property :id, Serial 
    property :email, String 

    property :password_digest, String, length: 60 

    def password=(password) 
    @password = password 
    self.password_digest = BCrypt::Password.create(password) 
    end 

end

Ich habe versucht, mit und ohne 'dm-Validierungen' aber es tut einen Unterschied machen.

Jede Hilfe wäre großartig.

Dank

Das Problem scheint in "validates_confirmation_of: password" zu sein, "validates_confirmation_of" ist eine Methode, die in 'DataMapper :: Resource' enthalten ist, aber diese Methode ist veraltet. Schau: http://www.rubydoc.info/gems/dm-validations/DataMapper/Validations/ValidatesConfirmation –

löste ich dieses Problem, indem die nach Deklarieren der Klasse

include DataMapper::Resource

Linie als die erste Zeile zu bewegen.
