title: When I put data on :notes and :place, the validation still fails
body: <p>I think, this code is correct but I don't know what happen? Here's my code:</p>
  
  <p>registration.rb :</p>
  
  <pre><code>class Registration &lt; ActiveRecord::Base
    attr_accessor :create_registration, :is_contact_registration, :is_appointment_registration
  
    validates :client_id, presence: true
    validates :type, presence: true
    validates :contact_thru, presence: true
    validates :purpose_message, presence: true,   :unless =&gt; :is_appointment_registration
    validates :action_needed, presence: true,     :unless =&gt; :is_appointment_registration
    validates :date_created, presence: true
    validates :owner_id, presence: true
    validates :status, presence: true
    validates :notes, presence: true  
  
  end
  </code></pre>
  
  <p>My controller,</p>
  
  <pre><code>  def create
      binding.pry
      @registration = Registration.new(record_params)
      @registration.owner_id = current_user.id
  
      @registration.is_appointment_registration = true
      if @registration.save
        render json: @registration, status: :created, location: @registration
      else
        render json: @registration.errors, status: :unprocessable_entity
      end
  
    end
  </code></pre>
  
  <p>The problem is, when I put data on <code>:notes</code> and <code>:place</code>, the validation still fails. </p>
