Filter combobox according to the list of projects created by each user logged in to Django

Question

I’m new to Jango and I have a lot to learn. I’m developing a system in which the logged-in user registers their requirement, but each requirement is tied to a project that the same user created. As it is a multi-tenant system, then multiple users will use the system and each registers its own project and requirement.

I’m getting the following message

AttributeError at /requisitos/cadastrarRequisito/
'User' object has no attribute 'projeto'
Request Method: GET
Request URL:    http://127.0.0.1:8000/requisitos/cadastrarRequisito/
Django Version: 3.1.2
Exception Type: AttributeError
Exception Value:    
'User' object has no attribute 'projeto'

Follow my model

class Requisito (models.Model):
    nomeRequisito = models.CharField(max_length=30, verbose_name=('Nome do Requisito'))
    responsavel = models.CharField(max_length=30, verbose_name=('Responsável pelo Desenvolvimento'))
    código = models.CharField(max_length=20, verbose_name=('Código do Requisito'))
    projeto = models.ForeignKey(Projeto, on_delete=models.PROTECT)
    prioridade = models.CharField(max_length=10, verbose_name=('Prioridade do Requisito'))
    risco = models.CharField(max_length=10, verbose_name=('Risco do Requisito'))
    motivo = models.CharField(max_length=20, verbose_name=('Motivo do Requisito'))
    status = models.CharField(max_length=20, verbose_name=('Status do Requisito'))
    requisitosImpactados = models.CharField(max_length=100, verbose_name=('Requisitos Impactados'))
    user = models.ForeignKey(User, on_delete=models.CASCADE)
    estoriaUsuario = HTMLField()
    regrasNegocio = HTMLField()

    def __str__(self):
        return self.nomeRequisito

Forms py.

class CadastrarRequisitos(ModelForm):
    def __init__(self, user, *args, **kwargs):
        super(CadastrarRequisitos, self).__init__(*args, **kwargs)
        self.fields['projeto'].queryset = Projeto.objects.filter(
             nomeProjeto=user.projeto.nomeProjeto)

    class Meta:
        model = Requisito
        fields = ['nomeRequisito',
                  'responsavel',
                  'código',
                  'projeto',
                  'prioridade',
                  'status',
                  'risco',
                  'motivo',
                  'requisitosImpactados',
                  'user',
                  'estoriaUsuario',
                  'regrasNegocio']

view

class RequisitoCreate(CreateView):
    model = Requisito
    form_class = CadastrarRequisitos
    
    def get_form_kwargs(self):
        kwargs = super(RequisitoCreate, self).get_form_kwargs()
        kwargs.update({'user': self.request.user})
        return kwargs

Model design

class Projeto(models.Model):
    nomeProjeto = models.CharField(max_length=20, verbose_name=('Nome do Projeto'))
    user = models.ForeignKey(User, on_delete=models.CASCADE)
    descricao = HTMLField()

How to make each requirement relate to a project that the respective logged-in user has registered and does not show this error message? Thank you very much, from now on.
