Django - Annotation not showing in template - django

Question

I'm trying to get annotations showing in my templates. I have two models (model1 and model2) and I want to show the number of model2's related to model1.
Here is my views.py:
def model2_count(request, pk):
model2count = models.Model1.objects.filter(pk=model1.pk).annotate(title_count=Count(‘model2__title'))
return render(request, 'model1/_model1.html', {‘m2c’: model2count})
Here is the template (model1/_model1.html):
I tried this:
{% for object in m2c %}</h3>
{{ object.title }}
{{ object.title_count }}
{% endfor %}
And tried this:
{% if m2c.title_count %}
{{ m2c.title_count }}
{% endif %}
I've been pulling my hair out over this for a couple days and can't figure it out. The following has been largely unhelpful:
Django - Annotating Weighted AVG by Group
Django: Annotation not working?
Django templates are not showing values of annotations
Django annotated value in template
What's frustrating is that I can't even say why applying these solutions hasn't worked.
Any input is appreciated.
Also, here are my models with all the BS taken out.
class Publication(models.Model):
title = models.CharField(max_length=150, unique=False, blank=False)
contributors_note = models.TextField(max_length=300, blank=False)

Answer 1

Bad mistake on my part. The solution's given above worked. Here is my final code:
views.py
class PublicationDetail(SelectRelatedMixin, generic.DetailView):
model = models.Publication
select_related = ("category", "user")
def get_queryset(self):
queryset = super().get_queryset()
return queryset.filter(user__username__iexact=self.kwargs.get("username")).annotate(assessment_count=Count('assessment'))
Fellow noobs that follow:
- It's easier for the people that want to help you (and faster for you) if you just post your original code instead of trying to get smart. Don't be embarrassed. I would've saved us all time if I had just done that.

Answer 2

First aggregations are done only using the field name i.e model2 not model2__title
Next getting counts of annotated columns recommended to use .values or values_list but not required.
https://docs.djangoproject.com/es/2.1/topics/db/aggregation/#cheat-sheet
model1 = Model1.objects.get(pk=model1.pk)
model2count = (
Model1.objects.annotate(count=Count('model2'))
.filter(pk=model1.pk)
.values_list('title', 'count', named=True)
)
template.html
{% for object in model2count %}
{{ object.title }}
{{ object.count }}
{% endfor %}
