JSON serializing Mongodb

Question

I am using the python package pymongo to retrieve data from a mongodb database.

>>> r = collection.find()   # returns an object of class \'Cursor\'
         


        

Answer 1

on my situation, this error is due to mongo DB id object in flask all you have to do is convert id if you need it else you can pop it too I'm sharing my solution which I figured out hope this helps someone

from flask import jsonify

def get_data(self,data):
     data['_id'] = str(data['_id'])
     return data

app =  Flask(__name__)

@app.route('/')
def apimethod():
     temp = [self.get_data(i) for i in self.critical.find()]
     return jsonify(temp)

also dumps from pymongo don't help alot

from bson.json_util import dumps,loads

because it is returning a string instead of dict which was expected in my situation to create API and I have to load again if I did dumps.
