Hi all,
      
I'm writing using Flask, Python 2.7.11, Sqlalchemy 1.0.11 and Postgresql 
9.4.6 to write a web application but 
I keep getting this error when I try to access the database. First, my 
config file:

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

SECRET_KEY = 'chara'
WTF_CSRF_ENABLED = True
WTF_CSRF_SECRET_KEY = 'csrf-chara'

LDAP_PROTOCOL_VERSION = 3
AD_PROVIDER_URL = 'ldap://ad.uillinois.edu:389/'
AD_BASE_DN = 'cn=%s,OU=People,DC=ad,DC=uillinois,DC=edu'
LDAP_PROVIDER_URL = 'ldap://ldap.illinois.edu:389'
LDAP_BASE_DN = 'OU=People,DC=uiuc,DC=edu'
#if os.environ.get('DATABASE_URL') is None:
#   SQLALCHEMY_DATABASE_URI = 'sqlite:///' + os.path.join(basedir, 'app.db')
#else:
SQLALCHEMY_DATABASE_URI = 
'postgres://erdwvldwaunpri:a9enrwrdx_zr9ptmamzs3bn...@ec2-54-227-245-197.compute-1.amazonaws.com:5432/dauoltmmkkfj08'
SQLALCHEMY_MIGRATE_REPO = os.path.join(basedir, 'db_repository')
SQLALCHEMY_TRACK_MODIFICATIONS = True




Then, I create my database ORM style:



#!flask/bin/python
from flask import Flask
from flask.ext.sqlalchemy import SQLAlchemy
from flask_login import LoginManager

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

login_manager = LoginManager()
login_manager.init_app(app)
login_manager.login_view = 'login'

from app.auth.views import auth
app.register_blueprint(auth)
db.create_all()


I can access the webpages and everything, but if I try to login or access 
the db I get the operational error. Can anyone help me with this? I've 
attached the full error file.
