Select in template does not update in edit - django

Question

I have the following code below, which would be the editing of a form of a request I made here for my work, as I had to change some of the views my update has to be manual, and the select field is not getting the result that I'm bringing it from the db, all fields are working except the select.
as it is now ||| as should be
class EditPedido(View):
def get(self, request, venda):
data = {}
venda = fixa.objects.get(id=venda)
data['filial'] = venda.regional
return render(request, 'fixa/fixa_update.html', data)
<select name="filial" class="select form-control" required="" id="filial">
<option value="" selected="">---------</option>
{% for filial in filiais %}
<option value="{{ filial.id }}">{{ filial.nome }}</option>
{% endfor %}
</select>
EDIT
class EditPedido(View):
def get(self, request, venda):
empresa_logada = request.user.funcionario.empresa
data = {}
data['filiais'] = empresa.objects.filter(nome=empresa_logada)
venda = fixa.objects.get(id=venda)
data['filial'] = venda.regional
return render(request, 'fixa/fixa_update.html', data)
<select name="filial" class="select form-control" required="" id="filial">
<option value="" selected="">---------</option>
{% for filial in filiais %}
<option value="{{ filial.id }}">{{ filial.nome }}</option>
{% endfor %}
</select>
<form method="POST" action="{% url 'create_fixa' %}">
{% csrf_token %}

Answer 1

So this is what you had in your last comment (I don't know where the space before the words in the third and fourth options are coming from, but perhaps you should remove them)
<select name="filial" class="select form-control" required="" id="filial">
<option value="" selected="">--------</option>
<option value="1">TESTE</option>
<option value="2"> SOROCABA</option>
<option value="5"> MARILIA</option>
</select>
You have the 1st option selected, which is --------. I think you want this
<select name="filial" class="select form-control" required="" id="filial">
<option value="1">TESTE</option>
<option value="2"> SOROCABA</option>
<option value="5" selected=""> MARILIA</option>
</select>
You will have to indicate to the template which option to select, you could pass this as a variable something like
data['selection'] = 5
Then in the template
<option value="{{ filial.id }}" {% if filial.id == selection %}selected=""{% endif %}>{{ filial.nome }}</option>
I'm not certain about the syntax of the {% if filial.id == selected %} statement. I don't use it much but the idea is to just put the tag in the option that requires it.
