[Fixed]-Django – best way of storing data created on the fly for a view/template

You can store your data in a list of dictionaries:

data = [
    {
        "template_name": "RTR-01",
        "device_name": "EDGE"
    },
    {
        "template_name": "SW-01",
        "device_name": "CORE"
    },
]

Then you will need to update the template’s context by overriding the render_to_response method.

def render_to_response(self, context, **kwargs):
    context.update({"data": data})
    return super().render_to_response(context, **kwargs)

And then you can iterate in your template

<ul>
{% for item in data %}
<li>{{item.template_name}}</li>
<li>{{item.device_name}}</li>
{% endfor %}
