Django serializer for one object

I'm trying to figure out a way to serialize some Django model object to JSON format, something like:

j = Job.objects.get(pk=1)
##############################################
#a way to get the JSON for that j variable???
##############################################

I don't want:

from django.core import serializers
serializers.serialize('json', Job.objects.get(pk=1开发者_Python百科),ensure_ascii=False)

Because it returns JSON array, not a single object representation.

Any ideas?

One way I'm thinking of: is to find a way to get a hash(attribute,value) of the object and then use simplejson to get the JSON representation of it, however I don't know how to get that hash.

How about just massaging what you get back from serializers.serialize? It is not that hard to trim off the square brackets from the front and back of the result.

job = Job.objects.get(pk=1)
array_result = serializers.serialize('json', [job], ensure_ascii=False)
just_object_result = array_result[1:-1]

Not a fancy answer but it will give you just the object in json notation.

Method-1

Use Django Serializer with python format

from django.core import serializers

j = Job.objects.get(pk=1)
response = serializers.serialize('python', [j], ensure_ascii=False)

Method-2

use json format while serializing and loads the string response

import json
from django.core import serializers

j = Job.objects.get(pk=1)
json_str_response = serializers.serialize('json', [j], ensure_ascii=False)
response = json.loads(json_str_response)[0]

Method-3

Use Django REST Framework's Serializer class define a serializer class and serialize the instance as

from rest_framework import serializers


class JobSerializer(serializers.ModelSerializer):
    class Meta:
        model = Job
        fields = '__all__'


j = Job.objects.get(pk=1)
response = JobSerializer(instance=j).data

Reference
1. Serializer Django model object

I would suggest using Django's model_to_dict. If I'm not mistaken, serializers.serialize() relies on it, too, but it only works for list, not single model instance. That's how you get a dict instance with your model fields out of a single model:

from django.forms.models import model_to_dict

# assuming obj is your model instance
dict_obj = model_to_dict( obj )

You now just need one straight json.dumps call:

import json
json.dumps(dict_obj)
