Django response in json format?

Question

Django

I'm trying to send data in json format, but I get an error:
Option 1
views.py

...
ingredients = Food.objects.values_list('id', 'title').filter(title__icontains=name)
response_data = serializers.serialize('json', ingredients)
return JsonResponse(response_data)

Mistake:

'tuple' object has no attribute '_meta'

Option 2
views.py

...
ingredients = Food.objects.values_list('id', 'title').filter(title__icontains=name)
return JsonResponse(json.dumps(ingredients), safe=True)

Mistake:

< QuerySet[(...)] > is not JSON serializable

Answer 1

The simplest solution

ingredients = Food.objects.values('id', 'title').filter(title__icontains=name)
return JsonResponse({'ingredients': list(ingredients)})

Answer 2

you need a JSON object or string that can be converted to JSON

Answer 3

JsonResponse accepts dict.
Alternatively, you can try to define a function in the model that will return an object as a dict.

ingredients = map(lambda food: food.to_json(), Food.objects.values_list('id', 'title').filter(title__icontains=name))
return JsonResponse(json.dumps(ingredients), safe=True)

It's worth using the Django REST Framework in the long run: djangorestframework.org
