I have one mongodb database and I have connected that db with pymongo in django. I am new to django, I am trying to get if the entered data present in the collection or not, if present return that record using get method

import pymongo
from pymongo import MongoClient
db_name = 'student_db'
client = MongoClient('localhost', 27017)
db_obj = client[db_name]
collection=db_obj['mongo_app_student']

@api_view(['GET'])
def test(request):
    data = request.data
    for x in collection.find():
        if data in x:
            print('entered a right value')
            return Response(data)

TypeError at /test unhashable type: 'dict'

I am getting this error when i am trying to get the output in postman. please help

First you Should use a POST request for that and since find() return a cursor, you're trying to iterate on a cursor. I'm not sure that's a good idea. And assuming request.data is a dict() try using == for comparison with x
Also Try casting what you get from mongo in a list like this :

import pymongo
from pymongo import MongoClient
db_name = 'student_db'
client = MongoClient('localhost', 27017)
db_obj = client[db_name]
collection=db_obj['mongo_app_student']

@api_view(['GET', 'POST'])
def test(request):
    response_data = None
    if request.method == 'POST':
        for x in list(collection.find()):
            if data == x:
                print('entered a right value')
                response_data = data
    return Response(response_data )

Let me know how it goes.
