How to make categories?

Question

Django

Good afternoon. I can't figure out how to make categories. Skinte please an example. I found a vidos with categories, I tried it, but something was not right. There was such

{% for c in categories %}
{{ c.name }}
{for p in posts}
{{p.name}}
{% endfor %}

In views it takes categories = Category.objects.all() and posts = Post.objects.all()
So did but it displays everything in all categories. How to make that would display under each of its own.

Answer 1

1) the Post must have a ForeignKey on the category
2) Then instead of posts in the template it will be possible to use c.post_set.all
3) It turns out that for each category there is a cycle through all the posts whose ForeignKey value corresponds to this category
