How can I register the project and add this app to flask-admin
my code:
__ __ INIT. RU
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 project in my custom app and I registered it, but when I want to add this to my admin to manage custom data, it throws the following exception:

I'm crazy about this

The collision is because you have a module username and a project called by the user. Rename the project to user_blueprint. From the code, it appears that you have a folder called user, a module called by the user, and a plan called by the user. You can avoid problems later with some descriptive names. Otherwise it is just confused.

If you have a drawing that already has a username, then your "admin" project must be named something else for your model view of administrators.
You can achieve this with var endpoint in ModelView
Flask-Admin - ModelView
admin.add_view(ModelView(Users, db.session, endpoint="users_"))

You can also override the admin command names in your ModelView subclass:
from flask_admin.contrib.sqla import ModelView
class AppModelView(ModelView):
def create_blueprint(self, admin):
blueprint = super(AppModelView, self).create_blueprint(admin)
blueprint.name = '{}_admin'.format(blueprint.name)
return blueprint
def get_url(self, endpoint, **kwargs):
if not (endpoint.startswith('.') or endpoint.startswith('admin.')):
endpoint = endpoint.replace('.', '_admin.')
return super(AppModelView, self).get_url(endpoint, **kwargs)
