Access ForeignKey set directly in template in Django

Question

I have this simplified model:

class Item(models.Model):
    name = models.CharField(max_length=120)

class ItemImage(models.Model):
    image = models.ImageF         


        

Answer 1

This worked for me, use the related_name in your models.

models.py

class Building(models.Model):
    address  = models.CharField(max_length=200, blank=True, null=True)
    city     = models.CharField(max_length=200, blank=True, null=True)

class Space(models.Model):
    title     = models.CharField(max_length=200, blank=True, null=True)
    building  = models.ForeignKey(Building, related_name="spaces_of_this_building")

buildings.html

{% for space in building.spaces_of_this_building.all %}
  {{ space.size }}
{% endfor %}
