flask下，实现简单博客2
创建数据库

drop table if exists entries;
create table entries (
id integer primary key autoincrement,
title string not null,
text string not null
);

将上面的代码保存到schema.sql 文件中。

创建views.py

from __future__ import with_statement

from sqlite3 import dbapi2 as sqlite3

from flask import Flask, request, session, g, redirect, url_for, abort, render_template, flash, _app_ctx_stack

# configuration

DATABASE = 'blog.db'

DEBUG = True

SECRET_KEY = 'development key'

USERNAME = 'admin'

PASSWORD = '123'

# create our little application :)

app = Flask(__name__)

app.config.from_object(__name__)

app.config.from_envvar('FLASKR_SETTINGS', silent=True)

def init_db():

"""Creates the database tables."""

with app.app_context():

db = get_db()

with app.open_resource('schema.sql') as f:

db.cursor().executescript(f.read())

db.commit()

在shell模式下运行

from flaskr import init_db
>>> init_db()

执行完后，将创建数据库和表。
