Django admin overriding - adding a print button

问题

I would like to create a "print button" inside an app in django admin interface to load a page in another browser tab (a view that is already coded) and let the user print it directly from admin interface.

I used the override to add a "print" button near the "history" button following this example: overriding admin templates

I have a model named "Card", each card has a unique number which is used to load a corresponding view, now I need to take this number and pass it to the print button to redirect to the page I want to print. How to get it?

I tried this

<a href="{{ ROOT_URL }}/my_app/{{ card.number }}" class="historylink">Print</a>

but it redirect to the root directory and doesn't take the value I need from the model.
