I need help picking up the values of an object in a list view
class Compraslist(LoginRequiredMixin, ListView):
model = Solicitacao
template_name = 'compraslist.html'
def get_context_data(self, **kwargs):
context = super(Compraslist, self).get_context_data(**kwargs)
context['solicitacoes'] = Solicitacao.objects.all()
return context
this is my list class, it lists the requests that have been made what I need is that it only lists the requests that have the Free status = 1
class Orcamento(models.Model):
anexo_descricao = models.CharField("Descrição do Arquivo" ,max_length=100)
anexo_orcamento = models.FileField("Anexar Arquivo", upload_to='media/uploads/anexos/')
anexo_relacionamento = models.ForeignKey(Solicitacao, on_delete=models.CASCADE)
ROLE_CHOICES = (
(1, 'Sim'),
(2, 'Não')
)
liberacao_compras = models.PositiveSmallIntegerField("Aprovar Solicitação?",
choices=ROLE_CHOICES,
default = 1,
)
def __str__(self):
return self.anexo_descricao
class Meta:
verbose_name = 'Orcamento'
verbose_name_plural = 'Orcamentos'
I tried to take it by the get_context_data as follows
class Compraslist(LoginRequiredMixin, ListView):
model = Solicitacao
template_name = 'compraslist.html'
def get_context_data(self, **kwargs):
context = super(Compraslist, self).get_context_data(**kwargs)
context['solicitacoes'] = Solicitacao.objects.all()
context['anexo'] = Orcamento.objects.filter(anexoRelacionamento=self.kwargs['pk'])
return context
but an error has been returned to me
context['anexo'] = Orcamento.objects.filter(anexoRelacionamento=self.kwargs['pk'])
Keyerror: 'pk'
Your filter should be in the request model. Solicitation.objects.filter(clears_purchases=1) The pk error is something else. You cannot find the key in the arguments coming from the context: tries: Organizing.objects.filter(annex_relationship=kwargs['id']) the attributes must be lowercase.

that
self.kwargs['pk']refers to the modelSolicitacaoorOrcamento? what is the url of this view?– JonatasCD
This pk Keyerror is because you are calling a parameter that has not been passed in your url. E reads in the Listview documentation, it is correct that you change the query in get_queryset and not in get_context_data.

The names aren’t right either. You have a view called Compraslist that uses a model called Request and the pk parameter you passed calls a Budget model. Think about whether it’s worth changing the name from Compraslist to Solicitacaodecompralist or Solicitacoeslist or something you prefer. And if you need to do a filter in Orcing with pk, change the url parameter to orcamento_pk because normally in urls when we use 'pk', this parameter is used in some filter of the main view model, which in this case is Request.
