POST & PUT method request confusions

I tried to build my own flask app, On that i faced some problems in PUT & POST requests, I gave my POST & PUT data in x-www-form-urlencoded in postman it works fine but when i go with raw data in postman below error came.

My code goes here-

class OrganisationList(Resource):

def __init__(self):
    self.reqparse = reqparse.RequestParser()
    self.reqparse.add_argument( 'org_name', required=True, help='No org name provided', location=['form', 'json'])
    self.reqparse.add_argument( 'org_phone1', required=True, help='No phone number provided', location=['form', 'json'])
    self.reqparse.add_argument( 'org_phone2', required=False, nullable=True, location=['form', 'json'], default=0)
    self.reqparse.add_argument( 'org_email', required=True, help='No email id provided', location=['form', 'json'])
    self.reqparse.add_argument( 'org_passkey', required=True, help='No org passkey provided', location=['form', 'json'])
    super(OrganisationList, self).__init__()

def get(self):
    organisations = [marshal(organisation, organisation_fields)
                    for organisation in models.Organisation.select()]
    return {'organisations': organisations}

def post(self):
    args = self.reqparse.parse_args()
    try:
        models.Organisation.create(**args)
    except models.IntegrityError:
        return 'some of the fields already exists'
    else:
        return 'saved successfully'

My JSON data: { "org_name": "ABC" "org_phone1": "1234567890" "org_email": "abc@xyz.com" "org_passkey": "admin1234" }

Error: { "message": { "org_name": "No org name provided" } }

But i gave my org_name in JSON. Help me to solve this issue. Thanks in advance.

Hi

I am not taking this course yet , but I can take a look at your JSON and spot a problem

 { "org_name": "ABC" "org_phone1": "1234567890" "org_email": "abc@xyz.com" "org_passkey": "admin1234" }


normally a Json is comma separated as in:

 { "org_name": "ABC", "org_phone1": "1234567890", "org_email": "abc@xyz.com", "org_passkey": "admin1234" }

if this points you in the right direction, plase mark question as answered.

Hi Mark Mneimneh thanks for your answer

In my actual JSON i made the request as a comma separated one but i failed to mark it here, Sorry fot that.

I found some solutions to make that work. But i'm not sure that is a correct way or may be some easy tricks other than this

I put my solution here-

def post(self):
    json_data = request.get_json(force=True)
    args = self.reqparse.parse_args()
    try:
        models.Organisation.create(**args)
    except models.IntegrityError:
        return 'some of the fields already exists'
    else:
        return jsonify('saved successfully')

On the POST method if i gave "json_data = request.get_json(force=True)" it works

Is that the only way or any easy ways are there.
