Django: generate download link

Question

I have a File model, which store path field - path in the filesystem to file. All files are stored in MEDIA_ROOT/files

In template I want g

Answer 1

In models.py:

import os

from django.conf import settings
from django.db import models

class File(models.Model):
    ... (your existing File model)

    @property
    def relative_path(self):
        return os.path.relpath(self.path, settings.MEDIA_ROOT)

(using the relpath method to strip MEDIA_ROOT from the value of self.path)

In your file_detail.html (or equivalent) template:

{{ file.name }}

NB as Chris says, it's better to use a FileField here. The above will hopefully work for your exact situation, but unless you're deeply committed to arranging things that way, I'd suggest changing to the dedicated field.
