Hi I have a question related to model inheritance and accessing the fields in a Django template.

My Model:

class Security(models.Model):
    name = models.CharField(max_length=100, blank=False)

class Stock(Security):
    wkn = models.CharField(max_length=15)
    isin = models.CharField(max_length=25)

class Asset(models.Model):
    security = models.ForeignKey(Security, on_delete=models.CASCADE,blank=False)

My views.py

context["assets"] = Asset.objects.all()

My template:

{% for asset in assets %}
   {{ asset.security.wkn }}
...

This gives me an error as wkn is no field of security.
Any idea how I can solve this?

Thanks in advance!
