How can i both register blueprint and add that app to flask-admin

Question

my Code:

__init__.py

from flask import Flask
from flask_admin import Admin
from flask_admin.contrib.sqla import ModelView
from flask.ext.sqlalchemy import SQLAlchemy

app = Flask(__name__)
app.config.from_object('config')
db = SQLAlchemy(app)

from user.user import mod as user
from user.models import User as userModel

app.register_blueprint(user, url_prefix='/user')

admin = Admin(app, name='My app')
admin.add_view(ModelView(userModel, db.session, name='userAdmin'))

user.py:

from flask import Blueprint, json
from flask.views import MethodView

mod = Blueprint('user', __name__)

class UserAPI(MethodView):
    def get(self):
        users = [
            {'nickname': 'Chan'},
            {'nickname': 'Hzz'},
        ]
        return json.dumps(users)

mod.add_url_rule('/users/', view_func=UserAPI.as_view('users'))

models.py:

from app import db

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)

    def __init__(self, username, email):
        self.username = username
        self.email = email

    def __repr__(self):
        return "<User %s>" % self.username

i have a blueprint in my user app, and i've registered it, but when i want to add this to my admin to manage the user data, it throws the below exception:

i am crazy about that

If you have a blueprint that has a name of users already then your 'admin' blueprint for your admin users model view needs to be called something different.
You can achieve this with the endpoint var in ModelView Flask-Admin - ModelView

admin.add_view(ModelView(Users, db.session, endpoint="users_"))
