Pass data from views.py into the plotly callback function

Dash Python

I’m working with node js and Django data connection. I have this middleware using node js that can send data using post request.

my node.js

const payload = mydata;
        //POST payload to django
        var obj = { data: payload };
        jsonobj = JSON.stringify(obj);
        var XMLHttpRequest = require("xhr2");
        var xhr = new XMLHttpRequest();
        xhr.open("POST", "http://127.0.0.1:8000/", true);
        xhr.setRequestHeader("Content-Type", "application/json;charset=UTF-8");
        xhr.send(jsonobj);

And I can access that data in my django project views.py using this following code. It’s printing the data that node js sent.

from django.views.decorators.csrf import csrf_exempt
import json

@csrf_exempt
def overview(request):
    if request.method == 'POST':
    post_data = json.loads(request.body.decode("utf-8"))
    value = post_data.get('data')
    print(value)

    return render(request, 'myhtml')

how can I pass this data (value = post_data.get(‘data’)) into a Plotly dash callback function. I tried this function, but I think it will not recognize request

 @app.callback(Output('graph-ph', 'figure'),
                  [Input('interval-graph-update', 'n_intervals')],
                  [State('graph-ph', 'figure')])
        def update_extend_traces_traceselect(n_intervals, fig_raw, request):
            if request.method == 'POST':
                post_data = json.loads(request.body.decode("utf-8"))
                value = post_data.get('data')
                print(value)
