how to retrieve an active storage attachment url as json in ruby

I'm trying to retrieve the URL of an active storage attachment as JSON response but i didn't quite get the correct respond here is my code:

#projet.rb

class Projet < ApplicationRecord
 has_many :appartements, dependent: :destroy
 has_one_attached :image_de_couverture
 has_one_attached :situation
 has_many_attached :images
end

#projet_serializer.rb

class ProjetSerializer < ActiveModel::Serializer
  include Rails.application.routes.url_helpers
  attributes :id, :nom, :gouvernorat, :localite, :surface, :description, :en_cours, :fini, 
  :situation, :images, :image_de_couverture

  def images
    object.images.map do |image|
      rails_blob_path(image, only_path: true) if object.images.attached?
    end
  end

  def image_de_couverture
    polymorphic_url(object.image_de_couverture, only_path: true) if 
    object.image_de_couverture.attached?
  end

  def situation
    polymorphic_url(object.situation, only_path: true) if object.situation.attached?
  end
end

#projets_controller.rb

class ProjetsController < ApplicationController
  # show all projects
  def index
    @projets = Projet.all
    render json: @projets
  end

  def set_projet
    @projet = Projet.find(params[:id])
  end

  def projet_params
    params.require(:projet).permit(:nom, :gouvernorat, :localite, :surface, :description, :situation, images: [])
  end
end

and here is the response i get with this code

[
  {
  id: 1,
  nom: "Test",
  gouvernorat: "Test",
  localite: "Test",
  surface: 30303,
  description: "Test",
  en_cours: true,
  fini: true,
  situation: "/rails/active_storage/blobs/redirect/eyJfcmFpbHMiOnsibWVzc2FnZSI6IkJBaHBFdz09IiwiZXhwIjpudWxsLCJwdXIiOiJibG9iX2lkIn19--50589feef3ab662f5fb9877dbf4f0a21c79e2412/lame_rideau1.jpg",
  images: [
  "/rails/active_storage/blobs/redirect/eyJfcmFpbHMiOnsibWVzc2FnZSI6IkJBaHBEdz09IiwiZXhwIjpudWxsLCJwdXIiOiJibG9iX2lkIn19--0550f31bd4e562c76dfd1aff9f0beac6483e1651/1.jpg",
  "/rails/active_storage/blobs/redirect/eyJfcmFpbHMiOnsibWVzc2FnZSI6IkJBaHBFQT09IiwiZXhwIjpudWxsLCJwdXIiOiJibG9iX2lkIn19--11ec06652e38fc43b54ef93187905f4591115d3c/2.jpg",
  ],
  image_de_couverture: null
  },
]

instead of

"/rails/active_storage/blobs/redirect/eyJfcmFpbHMiOnsibWVzc2FnZSI6IkJBaHBEdz09IiwiZXhwIjpudWxsLCJwdXIiOiJibG9iX2lkIn19--0550f31bd4e562c76dfd1aff9f0beac6483e1651/1.jpg"

i want to the link to the attachment.

Thanks in advance.

Try changing the rails_blob_path helper by rails_blob_url in your ProjetSerializer#images. You also need to set the host config in your application file. source

# config/application.rb

class Application < Rails::Application
  ...
  routes.default_url_options = { host: 'localhost:3000' }
end

def images
    object.images.map do |image|
      Rails.application.routes.url_helpers.rails_blob_url(image, only_path: true) if object.images.attached?
    end
  end
