python - flask Blueprint file structure -

i have troubles flask blueprint

structure of project:

hw ...run.py ...sigcontoj ......__init__.py ......admin .........__init__.py .........views.py .........models.py ......frontend .........__init__.py .........views.py .........models.py 

run.py:

from sigcontoj import create_app sigcontoj.frontend import frontend   app = create_app(__name__)   if __name__ == '__main__':     print app.url_map     print app.blueprints     app.run(debug = true) 

sigcontoj__init__.py:

from flask import flask flask.ext.sqlalchemy import sqlalchemy sigcontoj.frontend import frontend   db = sqlalchemy()  def create_app(name=__name__):     app = flask(name, static_path='/static')     app.register_blueprint(frontend, url_prefix=none)     app.secret_key = 'dfsdf1323jlsdjfl'     app.config['sqlalchemy_database_uri'] = 'sqlite:///soj.db'     db.init_app(app)     return app 

sigcontoj\frontend__init__.py:

from flask import blueprint  frontend = blueprint('frontend', __name__, template_folder='templates') 

sigcontoj\frontend\models.py:

from datetime import datetime sigcontoj import db   class news(db.model):     id = db.column(db.integer, primary_key=true)     title = db.column(db.string(256))     content = db.column(db.text)     publish_time = db.column(db.datetime, default=datetime.now())      def __repr__(self):         return '<news : %s>' % self.title 

sigcontoj\frontend\views.py:

from sigcontoj.frontend.models import news sigcontoj.frontend import frontend   @frontend.route('/') def index():     news = news.query.all()[0:5]     return "hello world" 

the output of app.url_map is

map([' (head, options, get) -> static>])

and index page 404.

are there mistake in code?

the issue have though import frontend blueprint since never import views index (/) route never registered frontend. if update sigcontoj/__init__.py import sigcontoj.frontend.views:

from flask import flask flask.ext.sqlalchemy import sqlalchemy sigcontoj.frontend import frontend import sigcontoj.frontend.views 

then should work.
