How can I represent foreign keys in templates?

How I can represent foreign keys in templates?

Models.py

class Trabajo(models.Model):
    titulo = models.CharField(blank=True, max_length=150)
    imagen = models.ImageField(upload_to='perfiles', verbose_name = 'Small image')
    descripcion = models.TextField()
    fecha = models.CharField(blank=True, max_length=150)
    link = models.CharField(blank=True, max_length=150)
    cliente = models.CharField(blank=True, max_length=150)

    def __unicode__(self):
        return self.titulo

class Imagen(models.Model):
    titulo_proyecto = models.ForeignKey(Trabajo, related_name='+')
    imagenes = models.ImageField(upload_to='perfiles', verbose_name = 'Imagen')

    def __unicode__(self):
        return unicode(self.titulo_proyecto)

Views.py

def index(request):
    trabajos = Trabajo.objects.all()
    imagenes = Imagen.objects.all()
    return render_to_response('index.html', {'works': trabajos, 'images': imagenes})

index.html

{% for item in works %}

    {% for obj in item.images.all %}
        {{obj.imagenes}}
    {% endfor %}

{% endfor %}

Okay, I think I know what you mean. First, you should clean up your view so it doesn't hit the database more often than it needs to. Change:

trabajos = Trabajo.objects.all()
imagenes = Imagen.objects.all()

to:

trabajos = Trabajo.objects.all().select_related()

Now try:

{% for item in works.imagen_set.all %}
    <img src="{{ MEDIA_URL }}{{ item }}" />
{% endfor %}
