extra context in django generic.listview

Question

So I have two models: Car and Picture. a car may have multiple pictures.

Now I want to use a list view to display all the cars along with one picture for each car, can someone tell me how can I do that? Below is my code

# models.py
class Car(models.Model):
  name = models.CharField(max_length=100)
class Picture(models.Model):
  car = models.ForeignKey(Car,related_name='pictures')
  picture = models.ImageField()

# views.py
class CarList(ListView):
  model = Car

Answer 1

List view has a method get_context_data. You can override this to send extra context into the template.

def get_context_data(self,**kwargs):
    context = super(CarList,self).get_context_data(**kwargs)
    context['picture'] = Picture.objects.filter(your_condition)
    return context

Then, in your template you can access picture object as you wish.

I guess this should solve your problem.
