Я пытался получить flask соединение с базой данных и обработать запрос

/ 27 мая 2020

Я пытался создать несколько моделей для своей базы данных и подключился с помощью flask -sqlalchemy. Я подключаю свою базу данных из connections.py в app.py и использую его функции, классы из функций в app.py. Все три модели создают базу данных после запуска flask. Мой код app.py 

from flask import (Flask, request, redirect, render_template, url_for, session, blueprints)

from flask_sqlalchemy import SQLAlchemy import config from connection import (db, users)

app = Flask(__name__)

app.config['SQLALCHEMY_DATABASE_URI'] = 'sqlite:///users.sqlite3' app.config['SQLALCHEMY_TRACK_MODIFICATIONS'] = False

app.config.from_object(config.DevelopementConfig)

#Link to main Page @app.route('/') def index():
    return render_template("index.html")

#Link to Login Page @app.route('/login', method = ["POST", "GET"]) def login():
    if request.method == "POST":
        user = request.form('username')
        password = request.form('password')
        #Checking if user exist
        check_usr = users.query.filter_by().first()
        if check_usr:
            session['username'] = check_usr.username
            session['password'] = check_usr.password
        return redirect(url_for('index'))
    else:
        #Checking if user is logged in
        if "username" in session:
            return redirect(url_for('index'))

    return render_template('login.html')

#Link to teachers report page @app.route('/report') def report():
    return render_template('report.html')

@app.route('/weekly_report') def weekly():
    return render_template('weekly.html')

@app.route('/view_weekly_report') def viewW():
    return render_template('vieww.html')


@app.route('/view_Daily_report') def viewD():
    return render_template('viewd.html')


@app.route('/daily_report') def daily():
    return render_template('daily.html')

#Link to children assessment page @app.route('/assessment') def asses():
    return render_template('assessment.html')


if __name__ == "__main__":
    db.create_all()
    app.run()

и это connections.py

Я не понимаю, что пошло не так, но получаю кучу ошибок. Я не могу их понять.

Я попытался отладить и изменить значение для __init__, но ответа не получил.
