how to count post by category django
#views.py
from django.db.models import Count
# You should change post in Count function based on your model.
categories = Category.objects.all().annotate(posts_count=Count('post'))
#Then you will have access to number of posts for each category:
for category in categories:
print(category.posts_count)
#in your template
{% for category in categories %}
<p>Number of posts: {{category.posts_count}}</p>
{% endfor %}
Are there any code examples left?
