Пробую regroup в шаблоні як написав N.E.M <br>
class BrandName(models.Model):<br>
name = models.CharField(max_length = 50, verbose_name = "Виробник")
<br>
class СarBatteries(models.Model):<br>
brand = models.ForeignKey(BrandName)<br>
name = models.CharField(max_length=63)<br>
cold_cranking_amps = models.PositiveSmallIntegerField(verbose_name = "Пусковий струм, А") <br>
cranking_amps = models.PositiveSmallIntegerField(verbose_name = "Ємність, Ah") <br>
views.py<br>
def index(request):<br>
batteries = СarBatteries.objects.order_by('brand', 'cranking_amps')<br>
brand = BrandName.objects.order_by('name')<br>
context = {
'batteries': batteries,
'brand': brand,
}<br>
return render(request, 'batteries/index.html', context)<br>
{% regroup batteries by brand.name as battery_list %}<br>
{% for brand in battery_list %}<br>
{{ brand.grouper }}<br>
{% for batter in battery_list %}<br>
{{batter.cranking_amps}}<br>
{{batter.cold_cranking_amps}}<br>
{% endfor %}<br>
{% endfor %}<br>
Але значення batter.cranking_amps і batter.cold_cranking_amps не виводить. В чому може бути причина?
