即使使用了python flask mysql，也无法将数据提交到数据库（使用python flask mysql）连接.提交()

Question

我正面临一个非常奇怪的问题。我的数据没有被存储在数据库中连接.提交（）在Python瓶里。这是我的代码：-在

from flask import Flask
from flaskext.mysql import MySQL
app = Flask(__name__)

def getMysqlConnection():

    mysql = MySQL()
    app.config['MYSQL_DATABASE_USER'] = "user_name"
    app.config['MYSQL_DATABASE_PASSWORD'] = "pass_string"
    app.config['MYSQL_DATABASE_DB'] = "db_name"
    app.config['MYSQL_DATABASE_HOST'] = "hostname"

    mysql.init_app(app)

    connection = mysql.connect()
    cursor = connection.cursor()
    return {"cursor":cursor,"connection":connection}

cursor = getMysqlConnection()['cursor']   #####global variables####
connection = getMysqlConnection()['connection']

def main_function():
    cursor.execute("Insert into table_name "
                       "(col1,col2,col3,col4) "
                       "Values (%s,%s,%s,%s,%s,%s)",
                       (val1,vla2,val3,val4)
                       )
    connection.commit()

这不是在数据库中保存代码。不知道为什么。在

任何帮助都会有帮助的。谢谢

Answer 1

下面的代码是否会初始化数据库连接两次？在

cursor = getMysqlConnection()['cursor']   #####global variables####
connection = getMysqlConnection()['connection']

试试看
