AssertionError: View function mapping is overwriting an existing endpoint function: index

This is my __init__.py:
import os

from flask import Flask
from flask_sqlalchemy import SQLAlchemy

basedir = os.path.abspath(os.path.dirname(__file__))

app = Flask(__name__)
app.config['SECRET_KEY']= '\xd4\xdf\xac\xf1\x1f\xcbGt\xd0,\xbb\xd9\x02\xaf/+n\x08\x13t\x9fd\x12g'
app.config['SQLALCHEMY_DATABASE_URI'] ='sqlite:///'+ os.path.join(basedir,'thermos.db')
app.config['SQLALCHEMY_TRACK_MODIFICATION'] = False
app.config['DEBUG']= True
db = SQLAlchemy(app)

import models
import views
import os

from flask import Flask
from flask_sqlalchemy import SQLAlchemy

basedir = os.path.abspath(os.path.dirname(__file__))

app = Flask(__name__)
app.config['SECRET_KEY']= 'its_a_secret'
app.config['SQLALCHEMY_DATABASE_URI'] ='sqlite:///'+ os.path.join(basedir,'thermos.db')
app.config['SQLALCHEMY_TRACK_MODIFICATION'] = False
app.config['DEBUG']= True
db = SQLAlchemy(app)

import models
import views

and my manaage.py is this:

#! /usr/bin/env python

from thermos import app, db
from thermos.models import User
from flask_script import Manager, prompt_bool

from thermos import db
from models import User

manager = Manager(app)

@manager.command
def initdb():
db.create_all()
db.session.add(User(username="olatunji",email="olatunji. [email protected]"))
db.session.add(User(username="Samuel",email="abiodun@Sam [email protected]"))
db.session.commit()
print 'Initialized the database'

@manager.command
def dropdb():
if prompt_bool(
"Are you sure you want to lose all your data"):
db.drop_all()
print 'Dropped the database'

if __name__ == '__main__':
manager.run()

and my model.py is this:
from datetime import datetime

from sqlalchemy import desc

from thermos import db

class Bookmark(db.Model):
id = db.Column(db.Integer,primary_key=True)
url = db.Column(db.Text,nullable=False)
date = db.Column(db.DateTime,default=datetime.utcnow)
description = db.Column(db.String(300))
user_id = db.Column(db.Integer,db.ForeignKey('user.id'),nullable=False)

@staticmethod
def newest(num):
return Bookmark.query.order_by(desc(Bookmark.date)).limit(num)

def __repr__(self):
return "<Bookmark '{}': '{}'>".format(self.description,self.url)

class User(db.Model):
id = db.Column(db.Integer,primary_key=True)
username = db.Column(db.String(80),unique=True)
email = db.Column(db.String(120),unique=True)
bookmarks = db.relationship('Bookmark',backref='user',lazy='dynamic')

def __repr__(self):
return "<User '{}'>".format(self.username)
how can I correct this error?
