Typeerror: Object Of Type Decimal Is Not Json Serializable

TypeError: Object of type Decimal is not JSON serializable While I am running in postman api i get the above error because sales_qty is decimal , I dont know how to parse decimal

Solution 1:

Use json.dump with cls argument, I believe that when ever the json module dont know how to convert, it will call the default function.

import json
import decimal

classEncoder(json.JSONEncoder):
    defdefault(self, obj):
        ifisinstance(obj, decimal.Decimal): returnfloat(obj)

json.dumps( ... , cls = Encoder)

```python

Solution 2:

import decimal

from flask import current_app as app
from flask import Jsonify
from flask.json import JSONEncoder

classJsonEncoder(JSONEncoder):
    defdefault(self, obj):
        ifisinstance(obj, decimal.Decimal):
            returnfloat(obj)
        return JSONEncoder.default(self, obj)

@app.route('/test_jsonify')deftest_jsonify():
    data = {
        'float': 7.5,
        'decimal': decimal.Decimal(7.5)
    }

    app.json_encoder = JsonEncoder
    return jsonify(data)
