This code recipe gives you an idea of how to use Flask-Admin with postgresql database.

from flask import Flaskfrom flask.ext.admin import Adminfrom flask.ext.admin import BaseViewfrom flask.ext.admin import exposefrom flask.ext.sqlalchemy import SQLAlchemyfrom flask.ext.admin.contrib.sqla import ModelViewapp = Flask(__name__)app.config['SECRET_KEY'] = '123456790'app.config['SQLALCHEMY_DATABASE_URI'] = 'postgresql://postgres:postgres123@localhost/scrapy'db = SQLAlchemy(app)admin = Admin(app)class MyView(BaseView):    @expose('/')    def index(self):        return self.render('index.html')class Cars(db.Model):        can_create = False        id = db.Column(db.Integer, primary_key=True)    name = db.Column(db.String(64))    price = db.Column(db.String(64))    admin.add_view(MyView(name='Hello'))admin.add_view(ModelView(Cars, db.session))if __name__ == '__main__':    app.run(host='0.0.0.0',port=8080,debug=True)
