### Configuração do formulário (forms.py)
```python

class AddressForm(forms.Form):
    address = forms.CharField(
        max_length=255,
        widget=forms.TextInput(attrs={'class': 'form-control'})
    )
    address_complement = forms.CharField(
        max_length=255,
        widget=forms.TextInput(attrs={'class': 'form-control'})
    )
    city = forms.CharField(
        max_length=255,
        widget=forms.TextInput(attrs={'class': 'form-control'})
    )
    state = forms.ChoiceField(
        choices=STATE_CHOICES,
        widget=forms.Select(attrs={'class': 'form-control'})
    )
    country = forms.CharField(
        max_length=255,
        widget=forms.TextInput(attrs={'class': 'form-control'})
    )
```
### Método de criação a recebimento da request (views.py)
```python
@login_required(login_url='/login/')
def address_create(request):
    form_submitted = False
    if request.method == 'GET':
        form = AddressForm()
    else:
        form_submitted = True
        form = AddressForm(request.POST)
        if form.is_valid():
            Address.objects.create(
                address=form.cleaned_data['address'],
                address_complement=form.cleaned_data['address_complement'],
                city=form.cleaned_data['city'],
                state=form.cleaned_data['state'],
                country=form.cleaned_data['country'],
                user=request.user
            )
            return redirect('/addresses/')

    return render(request, 'my_app/address/create.html', {'form': form, 'form_submitted': form_submitted})
```

### Formulário (create.html)
```python
<form action="/addresses/create/" method="post" {% if form_submitted %}class="was-validated"{% endif %}>
  {% csrf_token %}
  <div class="form-group">
      {{ form.address.label_tag }}
      {{ form.address }}
      <div class="invalid-feedback">
          {{ form.address.errors }}
      </div>
  </div>
  
  <div class="form-group">
      {{ form.address_complement.label_tag }}
      {{ form.address_complement }}
      <div class="invalid-feedback">
          {{ form.address_complement.errors }}
      </div>
  </div>
  
  <div class="form-group">
      {{ form.city.label_tag }}
      {{ form.city }}
      <div class="invalid-feedback">
          {{ form.city.errors }}
      </div>
  </div>
  
  <div class="form-group">
      {{ form.state.label_tag }}
      {{ form.state }}
      <div class="invalid-feedback">
          {{ form.state.errors }}
      </div>
  </div>
  
  <div class="form-group">
      {{ form.country.label_tag }}
      {{ form.country }}
      <div class="invalid-feedback">
