showing dynamic data from database in all views

I'm using Django 2.0

I have a Model within my notes application

notes/models.py

class ColorLabels(models.Model):
    title = models.CharField(max_lenght=50)

In the sidebar navigation which will be displayed on all pages, I want to show the list of color labels and it will show on all pages.

How can I show dynamic data in all views or say on all pages?

Use a custom template context processor.

This will add the context (data) you need into the templates rendered by all views.

First create the context processor (notes/context_processors.py):

from .models import ColorLabel

def color_labels(request):
    return {'color_labels': ColorLabel.objects.all()}

Then add it to the context_processors option of your template renderer in settings.py:

TEMPLATES = [{
    'BACKEND': '...',
    'OPTIONS': {
        'context_processors': [
            'notes.context_processors.color_labels',
            ...
        ],
    },
}]

Finally, you will be able to use it in your templates:

templates/base.html

<nav>
    {% for color_label in color_labels %}
        {{ color_label.title }}
    {% endfor %}
</nav>
