SQLAlchemy Flask ERROR: no such column XXX

[marcello86]

Hi there I'm trying to store a password in the db with SQLAlchemy, it's an FTP password that the application needs to submit some file, I was keeping the static pw in the code but for security reasons I cannot keep it in there, need to store it in the db. Here's the error:

OperationalError: (sqlite3.OperationalError) no such column: user.pwd
[SQL: SELECT user.id AS user_id, user.username AS user_username, user.pwd AS user_pwd
FROM user]
(Background on this error at: http://sqlalche.me/e/e3q8)
-------------------------------------------------------------
Here I create the table with columns in the db which already exists, and encrypt the password with bcrypt

#store_user_db.py

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

from flask import Flask 
from flask_sqlalchemy import SQLAlchemy
from sqlalchemy.ext.automap import automap_base

app = Flask(__name__)

app.config['SQLALCHEMY_DATABASE_URI'] = 'sqlite:///' + os.path.join(basedir, 'data-dev.sqlite')

db = SQLAlchemy(app)

Base = automap_base()
Base.prepare(db.engine, reflect=True)
User = Base.classes.user

class User(db.Model):

    id = db.Column(db.Integer, primary_key=True, autoincrement=True)
    username = db.Column(db.String(64), unique=True)
    pwd = db.Column(db.String(128))
    
    #db.create_all()    ??????? <-- Not sure about this if must be included or not
    
    #@hybrid_property
    def password(self):
        return self.pwd

    #@password.setter
    def _set_password(self, plaintext):
        self.pwd = bcrypt.generate_password_hash(plaintext)

--------------------------------------------------------------
Here I should store the password (I input the pw in the application with a GUI interface in python). Basically after I have stored it, I won't need this code again, I think I can make it run once and then delete the code? after has been stored I just need to retrieve the pw. Anyway I don't get this error, someone can help?

#installment_form.py

        
        from store_user_db import User, db
        #GUI password input
        DICP_FTP_DESTINATION_PSW=self.submit_pwd()

        user = User(username="ita_itf", pwd=DICP_FTP_DESTINATION_PSW)
        db.session.add(user)
        db.session.commit()

        results = db.session.query(User).all()
        flash(results)

        for r in results:
            print(r.username)
