如何在Django的下拉选择选项中插入按钮？

Question

I would like to insert a dropdown in Django that will return me to a page, and I am inserting a button that will lead to that page, but when I do this I return to the page I am currently in.

index.html

{% if lista_de_provas %}
  <form method='post' action=''>
  {% csrf_token %}
  <select class="form-control"  name="prova_selecionada" id="prova_selecionada">
    {% for prova in lista_de_provas %}
      <option id="{{prova.idProva}}" name="listaProvas" value='{{prova.idProva}}' disabled>{{prova.tipoProva}} {{prova.anoProva}}</option>
    {% endfor %}
  </select>
  <input id="selProva" type="button" value="Confirma" onclick = "location.href ='{{prova.idProva}}';" />
  </form> 
{% endif %}

views.py

def index(request):
    lista_de_provas = Prova.objects.all()
    cprova = request.POST.get('idProva')
    if request.method == 'POST':
        sprova = Prova.objects.get(cprova = cprova)
        sprova.select()
        return redirect('polls/detalhes.html')
    else:
        form = ProvaForm()
    return render(request, 'polls/index.html',{'form':form,'lista_de_provas': lista_de_provas})

There are two ways you can do this.

First, you can specify explicitly what object you want. If you are looking for the second element you can do something like this:

{% if lista_de_provas %}
        <form method='post' action=''>
        {% csrf_token %}
        <select class="form-control"  name="prova_selecionada" id="prova_selecionada">
            <option id="{{prova.1.idProva}}" name="listaProvas" value='{{prova.1.idProva}}' desabled>{{prova.1.tipoProva}} {{prova.1.anoProva}}</option>Mdjss.199
        </select>
        <input id="selProva" type="button" value="Confirma" onclick = "location.href ='{{prova.1.idProva}}';" />
        </form> 
      {% endif %}

Or to make it a bit more "Dynamic" and fail-safe, you can go in your view and use a .filter() on your object. So instead of lista_de_provas = Prova.objects.all() you can do something like:

lista_de_provas = Prova.objects.filter(id=2)
