Return JSON

Oi Thiago, tudo bem ?

Você consegue fazer algo assim :

from django.http import JsonResponse
return JsonResponse({'foo':'bar'})

Assim correto ?

from django.shortcuts import render, redirect
from perfis.models import Perfil
from django.http import JsonResponse
# Create your views here.
def index(request):
    perfis = Perfil.objects.all()

    return JsonResponse({'perfis':perfis})

Tá dando o seguinte error:

TypeError at /

Acho que pode fazer

def index(request):
    perfis = Perfil.objects.all()

    return JsonResponse({perfis})

from django.shortcuts import render, redirect
from perfis.models import Perfil
from django.http import JsonResponse
# Create your views here.
def index(request):
    perfis = Perfil.objects.all()

    return JsonResponse({perfis})

Olá Thiago, acho que você pode fazer dessa maneira

from django.shortcuts import render, redirect
from perfis.models import Perfil
from django.http import JsonResponse
# Create your views here.
def index(request):
    perfis = Perfil.objects.all()

    return JsonResponse(perfis, safe=False)

Ainda tá

Oi Thiago, tudo bem?

Acho que você consegue utilizar o módulo django.core.serializers

from django.shortcuts import render, redirect
from perfis.models import Perfil
from django.core import serializers


# Create your views here.
def index(request):
    perfis = Perfil.objects.all()

    return serializers.serialize("json", perfis)

Tudo bem Yuri, e contigo ?
