Question

我是python的新手所以我通过Flaskr教程创建了一个简单的聊天。当我到第4步创建数据库时，我得到以下错误：

>>> import __init__
>>> init_db()
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "__init__.py", line 34, in init_db
db = get_db()
File "__init__.py", line 29, in get_db
g.sqlite_db = connect_db()
File "__init__.py", line 22, in connect_db
rv = sqlite3.connect(app.config['DATABASE'])
NameError: global name 'connect' is not defined

这是__ init __。py：

# coding: utf-8
from flask import Flask, render_template, request, redirect, session, url_for, escape, g, abort, flash
from functools import wraps
from time import *
import locale
import os
import sqlite3

app = Flask(__name__)
app.config.from_object(__name__)
app.config.update(dict(
    DATABASE='chat.db',
    DEBUG=True,
    SECRET_KEY = "very secret",
    USERNAME="user",
    PASSWORD="password"
))
app.config.from_envvar("FLASKR_SETTINGS", silent=True)

def connect_db():
    rv = sqlite3.connect(app.config['DATABASE'])
    rv.row_factory = sqlite3.Row
    return rv

def get_db():
    if not hasattr(g, "sqlite_db"):
        g.sqlite_db = connect_db()
    return g.sqlite_db

def init_db():
    with app.app_context():
        db = get_db()
        with app.open_resource("schema.sql", mode="r") as f:
            db.cursor().executescript(f.read())
        db.commit()

#some @app.route

@app.teardown_appcontext
def close_db(error):
    if hasattr(g, "sqlite_db"):
        g.sqlite_db.close()

if __name__ == "__main__":
    app.run(debug=True)

这是schema.sql：

drop table if exists entries;

create table entries (

  id integer primary key autoincrement,
  name text not null,
  text text not null

);

抱歉我的英语不好，这不是我的第一语言。谢谢你的回答！
