You can build your own context processor where it will be run with each request and pass the data from there. You will find a detailed answer in this link (Django variable in base.html).

With Context Processors you can pass data to template. So, can use them every .html page.

your_project/context_processors.py

from .models import Category
def category_list(request):
    return {
        "category_urls": [
            {"name": category.name, "url": category.get_absolute_url()}
            for category in Category.objects.all()
        ]
    }

in settings.py

TEMPLATES = [
    {
        "BACKEND": "django.template.backends.django.DjangoTemplates",
        "DIRS": [str(BASE_DIR / "templates")],
        "APP_DIRS": True,
        "OPTIONS": {
            "context_processors": [
                "django.template.context_processors.debug",
                "django.template.context_processors.request",
                "django.contrib.auth.context_processors.auth",
                "django.contrib.messages.context_processors.messages",
                "my_app.context_processors. category_list"
            ],
        },
    },
]

in base.html

{% for category in category_urls %}
    
    {{category.name }}
{% endfor %}

You can use a custom context processor to add data to the template context for every request.

# myapp/context_processors.py
from .models import Category

def catgories(request):
    return {
        "categories": Category.objects.all()
    }

# settings.py
TEMPLATES = [
    {
        "BACKEND": "django.template.backends.django.DjangoTemplates",
        # ...your other settings....
        "OPTIONS": {
            "context_processors": (
                "django.contrib.auth.context_processors.auth",
                # ...other processors you use
                "myapp.context_processors.categories",
            ),
        },
    }
]

# my_template.html
{% for category in categories %}
     {{ category.name }}
{% endfor %}
