quickly access models attributes via foreign key relationship in django template - django

Question

I have a model where one field is a ForeignKey so that each child object is linked to a parent object.
In my (jinja2) templates, I list some attributes from a subset of objects from the child model, including one of the parents' attributes. The page loads very slowly, so I am wondering if there is a faster way to do the following:
views.py
class TransactionView(LoginRequiredMixin, ListView):
model = Transactions
context_object_name = 'transaction_list'
template_name = 'bank/transactions.html'
def get_queryset(self):
return Transactions.objects.filter(owner_id=self.request.user)
template.html
<tbody>
{% for transaction in transaction_list %}
<tr>
<td>{{transaction.source_document.service_provider}}</td>
<td>{{transaction.account}}</td>
<td>{{transaction.tnsx_date}}</td>
<td>{{transaction.end_bal}}</td>
<td>{{transaction.amount}}</td>
<td>{{transaction.category}}</td>
</tr>
{% endfor %}
</tbody>
models.py
class Transactions(models.Model):
def __str__(self):
return str(self.tnsx_uuid)
owner = models.ForeignKey(
User,
on_delete=models.CASCADE,
db_index=True,
editable=True,
)
source_document = models.ForeignKey(
Document,
on_delete=models.CASCADE,
editable=True,
)
tnsx_uuid = models.UUIDField(default=uuid.uuid4, unique=True)
account = IBANField(enforce_database_constraint=True)
currency = models.CharField(max_length=4, blank=False, null=False)
currency_assumed = models.BooleanField(null=False)
<etc>

As iklinac suggested, using .prefetch_related() increases the speed of the query dramatically.
change views.py to the following:
class TransactionView(LoginRequiredMixin, ListView):
model = Transactions
context_object_name = 'transaction_list'
template_name = 'bank/transactions.html'
def get_queryset(self):
return Transactions.objects.filter(owner_id=self.request.user).prefetch_related('source_document')
