Creating json array in django

Question

I am trying to make a json array in django but I am getting error -

In order to allow non-dict objects to be serialized set the safe parameter to False

and my views.py -

def wall_copy(request):
    if True:
        posts = user_post.objects.order_by('id')[:20].reverse()
        return JsonResponse(posts) 

Basically user_post is a model a posts is the object of top 20 saved data. I want to send a json array but I am unable to convert posts into a json array. I also tried serializers but it didnt helped.

I am stuck help me please.

Thanks in advance.

Answer 1

Would this solve your problem?

from django.core import serializers
def wall_copy(request):
    posts = user_post.objects.all().order_by('id')[:20].reverse()
    posts_serialized = serializers.serialize('json', posts)
    return JsonResponse(posts_serialized, safe=False) 

Answer 2

You can solve this by using safe=False:

    def wall_copy(request):
        posts = user_post.objects.all().order_by('id')[:20].reverse()

        return JsonResponse(posts, safe=False)

Note that it's not really unsafe - you just have to make sure on your own, that what you are trying to return can be converted to JSON.

See JsonResponse docs for reference.
