How can I post params to be used as an object in Django

I want to send an ajax Post request to my server with a param to be used like an object:

student_name = request.data.get('student_info', {}).get('name')

When I send the params like this:

student_info: {"name":"Tom", "age": 20}

It produce the following error:

AttributeError: 'unicode' object has no attribute 'get'

The best answer is what I don't need to change my back-end, and solve my problem by sending data properly.

Regards,

You should send a JSON Object from your client. Set 

Content-Type: application/json

in your request header and write your Object in the request body like so:

{"student_info":{"name":"Tom", "age": 20}}

Then you will directly get an object.

As easy as that :)

I hope you did stringify your data at the front-end. I once solved this problem by sending data from ajax as follows:

var js = {"name":"nguyen","age":"1"};
$.post("/", {'data': JSON.stringify(js)}, function(ret){
        console.log(ret)
    });

The request.data is just a string when posted from the front-end.

You could just do,

student_name = request.data.get('student_info', {})['name']

You could also do,

import json
student_name = json.loads(request.data.get('student_info')).get('name')

But, this may raise error if there is no student_info in request.data

Previous answer was a mistake from my side. Apologies from my behalf for that.

You need to send Json content and not key string values :

data: JSON.stringify({"student_info":"{'name':'Tom', 'age': 20}'})

your error is request.data.get('student_info', {}) return a string so you cannot retrieve the name with get('name')

And json.loads(request.data.get('student_info', {})) in Django part :)
