impossible d'afficher l'image dans un modèle Django (en utilisant ImageField)

Je télécharge une image du site d'administration dans le champ image du modèle. J'ai effectué les modifications nécessaires dans le fichier settings.py et urls.py et ajouté le répertoire multimédia dans mon projet. Bien que l'image apparaisse dans le site d'administration, j'obtiens l'erreur "L'attribut 'image' n'a pas de fichier associé" lors du rendu du modèle.

voici mes fichiers:

"""ProTwo URL Configuration

The `urlpatterns` list routes URLs to views. For more information please see:
    https://docs.djangoproject.com/en/2.0/topics/http/urls/
Examples:
Function views
    1. Add an import:  from my_app import views
    2. Add a URL to urlpatterns:  path('', views.home, name='home')
Class-based views
    1. Add an import:  from other_app.views import Home
    2. Add a URL to urlpatterns:  path('', Home.as_view(), name='home')
Including another URLconf
    1. Import the include() function: from django.urls import include, path
    2. Add a URL to urlpatterns:  path('blog/', include('blog.urls'))
