Django create path to an image file

I have a normal app that has a directory structure similar to the following:

...static/
      Training/
            css/
            img/
            js/
...templates/
   ....

Within one of my templates, I would like to get the image name from the database and build the path to the image. For example, if I had the image MyPicture.jpg, then I would like to include static and combine this with 'Training/img/' and the file name to get something like 

'..path to static../Training/img/MyPicture.jpg'

I found the following article that suggested using template tags, so I have tried this:

from django import template

register = template.Library()

@register.filter
def addstr(arg1, arg2):
    # Apparently, add has side effects, so use this:
    # https://stackoverflow.com/questions/4386168/how-to-concatenate-strings-in-django-templates
    return str(arg1) + str(arg2)

With the template:

{% with static|addstr:"Training/img/"|addstr:course.img as imgpath %}
<img class="card-img rounded-lg rounded-top" src="{{ imgpath }}" alt="Card image">
{% endwith %}

This is unfortunately leaving out the static part of the address.

How do I combine all three parts ?

[p.s. I have a {% load static %} at the top of the template ]

Thanks

Mark

Silly mistake really. All I needed to do was separate out the static and not treat it like a string. This works:

"{% static 'Training/img/'|addstr:course.img %}"

if you wanna show the absolute full url, this is what you need:

{{request.scheme}}://{{request.META.HTTP_HOST}}{{object.filefield.url}}

but if you just need to show the file, you can use this:

<img class="card-img rounded-lg rounded-top" src="{{ object.filefield.url }}" alt="Card image">
