How to JSON serialize __dict__ of a Django model?

model_to_dict() is what you need:

from django.forms.models import model_to_dictdata = model_to_dict(model)data['logo'] = data['logo'].urlreturn HttpResponse(json.dumps(data), content_type='application/json')

By specifying fields and exclude keyword arguments you can control what fields to serialize.

Also, you can simplify the try/except block by using the shortcut get_object_or_404():

model = get_object_or_404(Customer, id=id, user=1)

check the source code django/core/serializers/__init__.py comment:

Interfaces for serializing Django objects.Usage::    from django.core import serializers    json = serializers.serialize("json", some_queryset)    objects = list(serializers.deserialize("json", json))To add your own serializers, use the SERIALIZATION_MODULES setting::    SERIALIZATION_MODULES = {        "csv" : "path.to.csv.serializer",        "txt" : "path.to.txt.serializer",    }

for one object

json = serializers.serialize("json", some_queryset[0:1])

I found out that is is actually possible to use values() together with get(). You just have to fetch values from a filtered set.

def single(request, id):    user = 1    try:        models = Customer.objects.filter(id=id, user=user)        values = models.values().get()    except Customer.DoesNotExist:        raise Http404    string = json.dumps(values)    return HttpResponse(string, content_type='application/json')
