Rails 7 - has_many_attached delete old attachment when new is loaded-CodePudding

I'v got problem with Active Storage under Rails 7.

I read some posts but all are about Rails 5-6 and some methods was depreciated since then.

Problem - when I try to upload second photo, old is deleted. Why? How to fix this?

I have model:

class Profile
  has_many_attached :photos
  has_one_attached :avatar

in controller:

 class ProfilesController < ApplicationController

 

 def update

    Rails.logger.debug params.inspect
    @profile = current_user.profile

    @profile.update(profiles_params)


 private
# Only allow a list of trusted parameters through.
def profiles_params
    params.require(:profile).permit(:id, :email, :marketing, 
                                    :marketing_second, :terms, 
                                    :personal_data, 
                                    :birthdate, :avatar, :photos )
end

in view:

<%= form_for @profile do |f| %>  

    <div class='upload_container'>

       <%= f.file_field :photos, accept:'image/*', 
          :class=>'file_field_custom',  required: true  %>
       <%= f.button "Upload", type:'submit', :class=>'photos_submit_button' %>

    </div>

<% end %>

This was removed from Rails 7:

config.active_storage.replace_on_assign_to_many = false

Why action Destroy is fired.

@profile.photos.attach(params[:profile][:photos]) in update action of your controller
