Cannot display foreign key in Django list view

Question

I'm trying to display the foreign key information in my list view for the primary key and it's just not displaying and I cannot for the life of me figure out why.

Models:

Primary

class LightHouse(models.Model):
    customer = models.ForeignKey('users.CustomUser', on_delete=models.CASCADE,  related_name='lighthouse_group')
    context_object_name = 'lighthouse'
    lighthouseName = models.CharField(max_length=35, default="Not a lighthouse")

Foreign

class Endpoint(models.Model):

    lighthouse = models.ForeignKey(LightHouse, on_delete=models.CASCADE, related_name='LHName')
    device = models.CharField(max_length=50, unique=True)

Django Template for the PK

<tbody>
          {% for endpoint in lighthouse.endpoint_set.all%}
          <ul>
            <td>{{ endpoint.device }}</td>
            <td>{{ endpoint.endpointIPv4 }}</td>
            <td> Online </td>
          </ul>
          {% endfor %}
        </tbody>

What am I missing that it won't display the FK?

Answer 1

For your question "I cannot for the life of me figure out why." the reason is when you try to view a foreign key data you must view it as list of objects for your situation "lighthouse" is a foreign key for "LightHouse" Model so when try to view "lighthouseName" you should display it on this way "{{lighthouse.lighthouseName}}" for single row of data.

      {% for endpoint in lighthouse.endpoint_set.all%}
      <ul>
        <td>{{ endpoint.device }}</td>
        <td>{{ endpoint.lighthouse.lighthouseName}}</td>
        <td> Online </td>
      </ul>
      {% endfor %}
