Can't call a function to create a object on #route function even tough it works on python interpreter - database

Question

I'm creating a database for a school project and doing the backend between it and the app.(I'm using Flask and SQLAlchemy for it)
So the problem is that i can't call a function User(entrances), the function User() is a construction function used to create and object ,well it's what it looks like for me at least. But the function itself works when i do it in the interpreter.
WHY can i do it in my interpreter and can't do it on the flask tiny web framework???
here's the github link:BackEndRepository
Before taking a look at the samples here's the output form the interpreter that works:
Interperter
here's the code for my route:
from app import app,db
from models import User
from flask import render_template,Flask,request,redirect,url_for
#app.route('/index')
def index():
return "Hello, World!"
#app.route('/teste')
def teste():
users = db.session.query(User).all()
return u"<br>".join([u"{0}: {1}".format(user.name, user.email) for user in users])
#app.route('/teste2')
def teste2():
teste=User(name='susan',email='susan#example.com')
#u = User(name=request.args.get('1'), email=request.args.get('2'))
return teste
And here is the code for my model:
from app import db
class User(db.Model):
id = db.Column(db.Integer, primary_key=True)
name = db.Column(db.String(64), index=True, unique=True)
email = db.Column(db.String(120), index=True, unique=True)
def __init__(self,name,email):
self.name = name
self.email= email
def __repr__(self):
return '<User {0} {1}>'.format(self.name,self.email)
so i run in my terminal "flask run" and get the error in response:(theese is all the log i had after doing what i explained)

TypeError: 'User' object is not callable
The view function did not return a valid response. The return type must be a string, tuple, Response instance, or WSGI callable, but it was a User.

JUST highlighting the part that's bugging me out the most here:
TypeError: 'User' object is not callable

Answer 1

The problem is here:
#app.route('/teste2')
def teste2():
teste=User(name='susan',email='susan#example.com')
#u = User(name=request.args.get('1'), email=request.args.get('2'))
return teste
You are returning teste which is a User. That's not a valid return type here as the error tells you:
The return type must be a string, tuple, Response instance, or WSGI callable, but it was a User.
It's fine to return a string for example, so this should work:
#app.route('/teste2')
def teste2():
teste=User(name='susan',email='susan#example.com')
#u = User(name=request.args.get('1'), email=request.args.get('2'))
return teste.name
