I have problems with views - django

Question

I have this models:
Class Category(models.Model):
name = models.CharField(max_length=150, unique=True)
description = models.CharField(max_length=250)
def get_absolute_url(self):
return reverse('categories_url', args=[str(self.id)])
class Company(models.Model):
name = models.CharField(max_length=150, unique=True)
country = models.CharField(max_length=50)
class Motobike(models.Model):
name = models.CharField(max_length=150)
company = models.ForeignKey('Company', on_delete=models.CASCADE)
category = models.ForeignKey('Category', on_delete=models.CASCADE)
def get_absolute_url(self):
return reverse('details_url', args=[str(self.id)])
And views:
class CategoryView(DetailView):
model = Motobike
template_name = 'bikes_site/categories_detail.html'
pk_url_kwarg = 'pk'
def get_context_data(self, **kwargs):
context = super().get_context_data(**kwargs)
category = self.get_object()
context['motobikes'] = Motobike.objects.filter(category_id=category.pk)
return context
And test:
def test_category(setup):
client = Client()
category_id = Category.objects.get(name='Мотоциклы').id
response = client.get(f'/categories/{category_id}/')
assert response.status_code == 200
response_data = json.loads(response.content.decode('utf-8'))
assert len(response_data) == 2
assert response_data[1]['name'] == 'Ninja Turbo'
assert response_data[1]['vendor'] == 'Kawasaki'
assert response_data[1]['category'] == 'Мотоциклы'
assert response_data[1]['description'] == ''
response = client.get(f'/categories/25/')
assert response.status_code == 404
I need to present all thin in JSON, through JsonResponce, and what should almost go to the meaning of the dictonary, did i create them correctly?

You should do something like in your view:
from django.http import JsonResponse
class CategoryView(DetailView):
model = Motobike
template_name = 'bikes_site/categories_detail.html'
pk_url_kwarg = 'pk'
def get_context_data(self, **kwargs):
context = super().get_context_data(**kwargs)
category = self.get_object()
context['motobikes'] = Motobike.objects.filter(category_id=category.pk)
return JsonResponse(context, status=200) # or wahtever status is appropriate
Note: Haven't tested it, but that's what I use with GenericAPIView
