I am using the following code in views.py:

 class MatriculaCreateView(CreateView):
 template_name = "website/matricula.html"
 model = CursoPeriodoEstudante
 form_class = MatriculaMembroForm
 success_url = reverse_lazy("website:lista_estudantes")

 def get_context_data(self, **kwargs):
 context = super(MatriculaCreateView, self).get_context_data(**kwargs)
 context['estudante'] = Estudante.objetos.filter(id=self.kwargs['pk'])
 context['pk'] = self.kwargs['pk']
 return context

I create the following in forms.py:

 class MatriculaMembroForm(forms.ModelForm):

 class Meta:
 # Modelo base
 model = CursoPeriodoEstudante

 # Campos que estarão no form
 fields = [
 'estudante',
 'cursoPeriodo'

 ]

And finally in the template I created this page:

 % extends "website/_layouts/base.html" %

 % load widget_tweaks %

 % block title %Matricula de Membros% endblock %

 % block conteudo %
 <div class="container mt-5">
 <div class="row">
 <div class="col-lg-12 col-md-12 col-sm-12 col-xs-12">
 <div class="card">
 <div class="card-body">
 <h5 class="card-title">Matrícula de Membros</h5>
 <p class="card-text">
 Complete o formulário abaixo para matricular
 um <code>Membro</code> em um evento.
 </p>
 <p>Membro: estudante </p>
 <form method="post">
 <!-- Não se esqueça dessa tag -->
 % csrf_token %

 <!-- Estudante -->
 <div class="input-group mb-3">
 <div class="input-group-prepend">
 <span class="input-group-text">Estudante</span>
 </div>
 % render_field form.estudante class+="form-control" %
 </div>
 <hr>
 <!-- Curso -->
 <div class="input-group mb-3">
 <div class="input-group-prepend">
 <span class="input-group-text">Evento</span>
 </div>
 % render_field form.cursoPeriodo class+="form-control" %
 </div>
 <hr>
 <div class="text-right">
 <a href="% url 'website:lista_estudantes' %" class="btn btn-outline-primary">Voltar</a>
 <button class="btn btn-primary">Enviar</button>
 </div>
 </form>
 </div>
 </div>
 </div>
 </div>
 % endblock %

The problem is, when the page opens, I want the field "Estudante" already filled with the one I selected in the view through the get_context_data (This field can be fixed). But the field always comes like this:printscreen from page. How can I fix to come with the student like this. What can I do? Thank you!

Ps.: I tried to put the following, but nothing happened...

 class MatriculaCreateView(CreateView):
 template_name = "website/matricula.html"
 model = CursoPeriodoEstudante
 form_class = MatriculaMembroForm
 success_url = reverse_lazy("website:lista_estudantes")

 def get_initial(self):
 return 'estudante': Estudante.objetos.filter(id=self.kwargs['pk'])

 def get_context_data(self, **kwargs):
 context = super(MatriculaCreateView, self).get_context_data(**kwargs)
 context['estudante'] = Estudante.objetos.filter(id=self.kwargs['pk'])
 context['pk'] = self.kwargs['pk']
 return context

Override the get_initial() method of CreateView to set initial values for your model:

def get_initial(self):
 return 'estudante': Estudante.objects.get(id=self.kwargs['pk'])

I got it!
I should change the view to get, instead of filter (a query).

Thanks!
