default context for all pages Django

Question

I was wondering if there's any way of sending a default context for all pages in django, such as user is always passed to the template regardless of other context, for my particular case i want to send context for navbar such as category and sub category to all pages without having to send in all the views. TIA

You can achieve this by creating a context processor. Create a context_processors.py in any app, I suggest doing it on your main app. And here you can create context dictionaries. Like so:

from product.models import SubCategory, Category


def add_variable_to_context(request):
    return {
        'subCategories': SubCategory.objects.order_by('id').all(),
        'categories': Category.objects.order_by("id").all(),
    }

Add this line to your TEMPLATES in settings.py to call the created context processor

'OPTIONS': {
    'context_processors': [
        ....
        'yourAppName.context_processors.add_variable_to_context',
        ....
    ],
},

Now you can call your created context dictionaries in your base.html
