django如何在模板中显示子查询

我的看法是:

credits = Credit.objects.filter(account=OuterRef('pk')).values('account_id').annotate(sum_credits=Sum('amount'))
debits = Debit.objects.filter(account=OuterRef('pk')).values('account_id').annotate(sum_debits=Sum('amount'))
dif = Account.objects.annotate(credit_sum=Subquery(credits.values('sum_credits')),debit_sum=Subquery(debits.values('sum_debits')),balance=F('credit_sum') F('debit_sum')).values_list('name', 'balance')

我的模板:

{% for account in dif %}
<tr>
  <td>{{ account }}</td>
  <td></td>
  <td></td>
  <td></td>
</tr>
{% endfor %}

结果:

('andrea', 10)          
('mosca', 20)           

如何删除括号?
