Using annotate for more than one value in django

I'm Trying to perform a query that uses annotation. But the problem is I need to annotate for 2 values without having the item showed 2 times in my template .. here are the files for a better understanding.
Those are the models I use:
class Daily(models.Model):
date = models.DateTimeField(auto_now=True)
text = models.CharField(max_length=80) #
maden = models.IntegerField(default=0) #
maden_from_type = models.ForeignKey(Type, on_delete=CASCADE, blank=True, null=True)
maden_from_cat = models.ForeignKey(Category, on_delete=CASCADE, blank=True, null=True)
da2en = models.IntegerField(default=0)
da2en_from_type = models.ForeignKey(Type, on_delete=CASCADE, related_name='da2en_from_type', blank=True, null=True)
da2en_from_cat = models.ForeignKey(Category, on_delete=CASCADE, related_name='da2en_from_cat', blank=True,
null=True)
farm = models.ForeignKey(Farm, on_delete=CASCADE)
is_invoice = models.BooleanField(default=False)
class Type(models.Model):
type_name = models.CharField(max_length=80)
def __str__(self):
return self.type_name
class Category(models.Model):
category_name = models.CharField(max_length=80)
type = models.ForeignKey(Type, on_delete=CASCADE)
def __str__(self):
return self.category_name
And that is how I tried to execute the annotate in the views:
def mezan(request):
all_daily = Daily.objects.values('da2en_from_cat__category_name', 'maden_from_cat__category_name').annotate(
all_maden=Sum('maden',distinct=True)).annotate(
all_da2en=Sum('da2en',distinct=True))
context = {
'all_daily': all_daily,
}
return render(request, 'mezan.html', context)
Finally, when I try to view it in my HTML templates, it duplicates the item if it has value in both annotated fields.
{% for item in all_daily %}
<tr>
<td>{{item.da2en_from_cat__category_name}}</td>
<td>{{item.all_da2en}}</td>
<td">{{item.all_maden}}</td>
</tr>
{% endfor %}
I need to show it once with the 2 values being displayed. But it is being shown twice with one value for each
Image for the result
