In the code above, you first import thesqlite3module to use it to connect to your database. Then you import theFlaskclass and therender_template()function from theflaskpackage. You make a Flask application instance calledapp. You define a function calledget_db_connection(), which opens a c...
You define a function calledget_db_connection(), which opens a connection to theflask_dbdatabase using the user and password you store in yourDB_USERNAMEandDB_PASSWORDenvironment variables. The function returns theconnconnection object you’ll be using to access the database. Then you create...

这个得看下具体的代码片段，哪里传的database参数，看下url连接串咋写的呀

Adding to what @zzzeek wrote, this pattern can (will) create problems if your Flask project is run in a forking model and you invoke that code before the fork. See: "Working with Engines and Connections : Engine Disposal" "Connection Pooling : Using Connection Pools with Multiprocessing" "...
In web applications this connection is typically tied to the request. It is created at some point when handling a request, and closed before the response is sent. flaskr/db.py import sqlite3 import click from flask import current_app, g def get_db(): if 'db' not in g: g.db = sql...
Flask needs a database connection per request context, and that is registered to close in route.py """db = getattr(g,'_database',None)ifdbisNone: db = g._database= sqlite3.connect(db_name)returndb 开发者ID:jedimatt42,项目名称:tipi,代码行数:11,代码来源:tipi_cache.py ...
