How to I return JsonResponse from Paginator's page? Object of type Page is not JSON serializable

(this is my first stackoverflow question ever)

I want to return JsonResponse from the dictionary "context" (seems to be a paginator Page) as coded below:

myposts = userposts.all().values()
myfollowers = userfollowers.ffollowers.all()
myfollowings = userfollowers.ffollowings.all()

context = {"posts": page_obj,
    "loops": range(1, totalpages + 1),
    "user": uprofile.username,
    "myposts": list(myposts),
    "mypostsnum": len(userposts.all()),
    "myfollowers": list(myfollowers),
    "myfollowersnum": len(userfollowers.ffollowers.all()),
    "myfollowings": list(myfollowings),
    "myfollowingsnum": len(userfollowers.ffollowings.all())
}

this is the return I use:

return JsonResponse(context, safe=False)

Result I get:

Object of type Page is not JSON serializable

My question is how do I get JsonResponse from 'context'?

Solution

  • The problem is with "posts": page_obj. page_obj is an instance of a model. Like page_obj = Post.objects.get(pk=1).

    JsonResponse will call json.dumps() on your context and is failing because it doesn't know how to handle a object.

    I would recommend you to use Django rest framework for this. Serializers is used just for this problem.
