Cependant, lorsque je rends la page, la section input-group-append ne semble pas fonctionner. Voici une capture d'écran:

Cependant, cela ne ressemble clairement pas aux exemples ici .

Pas sûr de ce que je devrais faire différemment ici, s'agit-il d'un bogue avec la version bêta de Bootstrap 4.0? 

Note supplémentaire rapide, au cas où cela serait pertinent, j'utilise Django 2.0.

Il n'y avait pas de bugs.

Vous avez inclus beaucoup d'inutiles. Les jQuery font beaucoup de perturbations. Soyez prudent lorsque vous ajoutez des scripts susceptibles d'entrer en conflit. Se référer à mon code

Je viens de rencontrer celui-ci aujourd'hui. J'ai vérifié deux fois mes styles et mes scripts et tout va bien. Au lieu d'utiliser append et preped, j'ai utilisé input -group-addon et input-group-btn.

S'il vous plaît voir ce lien .

Bootstrap 4 est sorti de l'alpha (4.1 au moment de cette réponse) et devrait fonctionner maintenant:

  <div class="form-group">
    <label for="price">Price</label>
    <div class="input-group-btn">
      <div class="input-group-prepend">
        <span class="input-group-text">$</span>
        <input id="price" type="number" class="form-control" />
        <span class="input-group-text">.00</span>
      </div>
    </div> 
  </div>

Donc, utilisez la classe input-group-btn avec input-group-prepend (ou input-group-prepend) et input-group-text.

Vérifiez la documentation de la version 4.1 pour le groupe d’entrée ici .
