I'm building a REST API using flask. I'm using postman for testing a route that creates a new item in my database, but only if the user is logged in. The routes for registering and login are working well, the last one returns the token using flask_jwt_extended module. When I send a post request to my "/api/notes" (creates a new note in database) I get the error bellow:
" (...) raise TypeError(f'Object of type {o.class.name} '
TypeError: Object of type function is not JSON serializable"
for the request I'm using the authorization tab of postman. type: Bearer Token, and my token in the field (tried with and without quotation marks)
I had faced this error this morning, before implementing my one-many relantionship, but I got it working by replacing my VERY_LONG_TOKEN with "VERY_LONG_TOKEN" in the Barear token field. I thought that because the token includes dots, it was interpreting as a function. But after implementing the relationship, I went to test and got this error again.
my note.py file:
from flask import request, Response, jsonify
from app.models import User, Note
from flask_restful import Resource
from flask_jwt_extended import jwt_required, get_jwt_identity
class NotesApi(Resource):
def get(self):
notes = Note.objects().to_json()
return Response(notes, mimetype="application/json", status=200)
@jwt_required
def post(self): # post method I'm making a request for
print("fool") # this doesn't get printed -> not reaching
user_id = get_jwt_identity()
data = request.get_json(force=True)
if data:
user = User.objects(id=user_id) # logged in user
note = Note(**data, user_author=user) # creates note with the author
note.save()
user.update(push__notes=note) # add this note to users notes
user.save()
id = str(note.id)
return {'id': id}, 200
else:
return {'error': 'missing data'}, 400
my models.py:
from app import db # using mongodb
from datetime import datetime
from flask_bcrypt import generate_password_hash, check_password_hash
class Note(db.Document):
title = db.StringField(max_length=120,required=True)
content = db.StringField(required=True)
status = db.BooleanField(required=True, default=False)
date_modified = db.DateTimeField(default=datetime.utcnow)
user_author = db.ReferenceField('User')
class User(db.Document):
username = db.StringField(max_length=100, required=True, unique=True)
email = db.StringField(max_length=120, required=True, unique=True)
password = db.StringField(required=True)
remember_me = db.BooleanField(default=False)
notes = db.ListField(db.ReferenceField('Note', reverse_delete_rule=db.PULL)) # one-many relationship
def hash_password(self):
self.password = generate_password_hash(self.password).decode('utf8')
def check_password(self, password):
return check_password_hash(self.password, password)
User.register_delete_rule(Note, 'user_author', db.CASCADE)

body of my post request:
{
"title": "test0",
"content": "test0"
}
Did anyone faced it before or know how to solve it?
Edit: added more code info
