Wenn ich die Seite tatsächlich rendere, scheint der input-group-append-Abschnitt jedoch nicht zu funktionieren. Hier ist ein Screenshot:

 Rendered page screenshot

Dies sieht jedoch eindeutig nicht wie in den Beispielen hier aus.

Nicht sicher, was ich hier anders machen soll. Ist dies ein Fehler in der Bootstrap 4.0 Beta? 

Schnelle zusätzliche Anmerkung, falls es irgendwie relevant ist, verwende ich Django 2.0.

Es gab keine Fehler.

Sie haben eine Menge unnötiger Dinge aufgenommen. Die jQuery stört viel. Seien Sie vorsichtig, wenn Sie Skripts hinzufügen, die in Konflikt geraten können. Siehe meinen Code

Ich bin gerade heute diesem begegnet. Ich habe meine Stile und Skripte noch einmal überprüft und alles ist gut. Statt Append und Preped zu verwenden, habe ich die Eingabe -group-addon und input-group-btn verwendet.

Bitte sehen Sie diesen Link .

Bootstrap 4 hat Alpha verlassen (4.1 zum Zeitpunkt dieser Antwort) und Folgendes sollte jetzt funktionieren:

  <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>

Verwenden Sie also die Klasse input-group-btn zusammen mit input-group-prepend (oder input-group-prepend) und input-group-text.

Überprüfen Sie die Dokumentation der Version 4.1 für die Eingabegruppe hier .
