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。
