How do I traverse a generic relationship in a Django template?

Question

I would like to traverse generic relationships in my Django template, similar to how you can traverse FK relationships.

Models.py

class Company(models.Model):
    name = models.CharField(blank=True, max_length=100)
    notes = models.TextField(blank=True)

class Address(models.Model):
    address = models.TextField(max_length=200)
    content_type = models.ForeignKey(ContentType)
    object_id = models.PositiveIntegerField()
    content_object = generic.GenericForeignKey('content_type', 'object_id')

This does not seem to work in my template:

{{ company.address_set.all }}

Any help is appreciated.

Answer 1

Your Company model doesnt know about the adresses, you could try this:

class Company(models.Model):
    name = models.CharField(blank=True, max_length=100)
    notes = models.TextField(blank=True)
    addresses = generic.GenericRelation('Address', blank = True)

In your template you can do something like this :

{% for address in company.addresses.all %}
{{ address.town }}, {{ address.street }}
{% endfor %}

Hope this helps.
