python - Django: How to display a pdf file in a new tab?

Question

Most of the posts showing how to open a pdf file in a new tab are 3 years old. What is the best way in Django to open a pdf file uploaded to a model?

invoice.py

class Invoice(models.Model):
    
    file = models.FileField(upload_to='estimates/', blank =True)
    name = models.CharField(max_length=250, blank =True)    

    def __str__(self):
        return self.name

views.py

def view_invoice(request, invoice_id):
    invoice = get_object_or_404(Invoice, pk=invoice_id)
    return render(request, 'index_invoice.html', {'invoice': invoice}) 

index_invoice.html

<a href=""><i class="fas fa-eye"></i>&nbsp;</a>

Many Thanks

Answer 1

You should be able to use the FileField's url:

<a href="{{ invoice.file.url }}"><i class="fas fa-eye"></i>&nbsp;</a>
