How to display the model on all pages?

Question

Django

I have a model that I display in the header through for, but I don't like what I write in each function. I tried using templatetags
Categorie.objects.all().order_by('id')

@register.simple_tag(takes_context=True)
def header_categories(context):
  return Categorie.objects.all().order_by('id')

but it doesn't work in the template.

{%header_categories%}
  {% for cat in header_categories %}
    cat.text
  {% endfor %}

How to fix it?

Answer 1

this is not a model, but a queryset type, put the template where you display
it in another template
