python - Setting up postgres with flask on win7 -


enter image description here

i working on flask app based on http://code.tutsplus.com/tutorials/intro-to-flask-signing-in-and-out--net-29982.

as part of tut i'm trying connect postgres server, structure in screenshot. i've added table 'yournewdb' can see.

based on tut have following code in main file ('routes.py'):

app.config['sqlalchemy_database_uri'] = "postgresql://postgres:123@localhost/yournewdb"  models import db db.init_app(app)  @app.route('/testdb') def testdb():   if db.session.query("1").from_statement("select 1").all():     return 'it works.'   else:     return 'something broken.'

models.py:

from flask.ext.sqlalchemy import sqlalchemy werkzeug import generate_password_hash, check_password_hash  db = sqlalchemy()  class user(db.model):   __tablename__ = 'users'   uid = db.column(db.integer, primary_key = true)   firstname = db.column(db.string(100))   lastname = db.column(db.string(100))   email = db.column(db.string(120), unique=true)   pwdhash = db.column(db.string(54))    def __init__(self, firstname, lastname, email, password):     self.firstname = firstname.title()     self.lastname = lastname.title()     self.email = email.lower()     self.set_password(password)    def set_password(self, password):     self.pwdhash = generate_password_hash(password)    def check_password(self, password):     return check_password_hash(self.pwdhash, password)

when go http://127.0.0.1:5000/testdb i'm getting internal server error. debugger gives:

c:\envs\virtalenvs\flask_mini\lib\site-packages\flask_sqlalchemy\__init__.py:800: userwarning: sqlalchemy_track_modifications adds significant overhead , disabled default in future.  set true suppress warning.   warnings.warn('sqlalchemy_track_modifications adds significant overhead , disabled default in future.  set true suppress warning.')  * running on http://127.0.0.1:5000/ (press ctrl+c quit) c:\envs\virtalenvs\flask_mini\lib\site-packages\sqlalchemy\sql\elements.py:3779: sawarning: textual sql expression 'select 1' should explicitly declared text('select 1') (this warning may suppressed after 10 occurrences)   {"expr": util.ellipses_string(element)})

what doing wrong?

seems you're connecting table, not db, correct? why don't change yournewdb postgres or make new db? you'll still have make table. can have sqlalchemy you. here great answer on that: https://stackoverflow.com/a/20749534/2326132

i'd suggest making new database each project, if test projects. you'll run fewer issues.

ios - Realm over CoreData should I use NSFetchedResultController or a Dictionary? -

i'm working on app using core data , nsfetchedresultcontroller many reasons switch use realm. saw there "realm version" of nsfetchedresultcontroller on github wouldn't compatible current code using core data. the view controller displaying list of people same school, address book. list sublist of people studied in same city. so thinking make 1 unique request database retrieve list of people , filter locally list within 1 dictionary per school [string: anyobject] string section name within tableview , anyobject array of people. first solution, make nsfetchedresultcontroller each school predicate filtering location. delete actions etc.. handled delegates -> not compatible realm create dictionaries , update them each actions... -> works realm it's annoying code. any better solution? edit: i need clarify request: i'd write class inherit uitableviewcontroller. this class has list of people sorted in alphabetical order the tableview has ...
