How to filter a selection in a template?

Question

Django

I have:

class Data(models.Model):
    user = models.ForeignKey(settings.AUTH_USER_MODEL, verbose_name=_('User'))
    number = models.CharField(_('Number'), unique=True, max_length=6)

class Wallet(models.Model):
    user = models.ForeignKey(settings.AUTH_USER_MODEL, verbose_name=_('User'))
    data = models.ForeignKey(m.Data, null=True, verbose_name=_('Data'))

class DataListView(LoginRequiredMixin, TemplateView, BaseContextMixin):
    template_name = "data/list.html"
    login_url = reverse_lazy('users:login')

    def get_context_data(self, **kwargs):
        context = super(DataListView, self).get_context_data(**kwargs)
        context['my_data'] = self.request.user.data_set.all()
        return context

then I output in the template:

{% for one in my_data %}

{% endfor %}

And I get the data of the current user: context['my_data'] = self.request.user.data_set.all()
Everything is fine, but inside the for loop I need to display all wallets of this user for this date. I use

{% for wallet in one.wallet_set.all %}

{% endfor %}

As a result, I get all wallets that do not even belong to the current user. How to set up a filter so that wallets are only from the current user? How to use filter by models in templates?

no way.
Disgusting practice
Filter in the model, as a last resort, in the view
