Carrierwave return nil for image link after uploading. Rails 6.1

Question

Hellow everyone! After clone, My app won't upload photos from PC! It look like data base saving all photo params, but only for adress return nil. Photo.last -> #<Photo id: 12, photo: nil, event_id: 59, user_id: 4, created_at: "2022-03-31 06:29:36.880107000 +0000", updated_at: "2022-03-31 06:29:36.880107000 +0000"> but presence :true validation is mode on. my form.html:

<%= form_for [@event, photo], html: { multipart: true } do |f| %>

  <div class="form-group">
    <%= f.label :photo %>
    <%= f.file_field :photo %>
  </div>
  <div class="actions">
    <%= f.submit 'upload', class: 'btn btn-primary' %>
  </div>
<% end %>

my photo_uploader.rb:

class PhotoUploader < CarrierWave::Uploader::Base
  include CarrierWave::RMagick

  if Rails.env.production?
    storage :fog
  else
    storage :file
  end

  def store_dir
    "uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}"
  end

  def extension_allowlist
    %w(jpg jpeg gif png)
  end
end

My model Photo.rb:

class Photo < ApplicationRecord
  belongs_to :event
  belongs_to :user

  validates :event, presence: true
  validates :user, presence: true
  validates :photo, presence: true

  mount_uploader :photo, PhotoUploader

  scope :persisted, -> { where "id IS NOT NULL"}
end

My photo_controller.rb:

class PhotosController < ApplicationController
  before_action :set_event, only: [:create, :destroy]
  before_action :set_photo, only: [:destroy]

  def create
    @new_photo = Photo.new(event: @event)
    
    @new_photo.user = current_user
  end

  private

  def photo_params
    params.fetch(:photo, {}).permit(:photo)
  end
  def set_event
    @event = Event.find(params[:event_id])
  end
  def set_photo
    @photo = @event.photos.find(params[:id])
  end
end
