python html提交表单数据库,html - 如何使用Python将输入表单HTML从发送到SQLite3数据库？ - SO中文参考 - www.soinside.com...
我正在尝试为到达办公室的客人创建客人登记表。我无法将输入从表单发送到SQLite3数据库。
如果有人可以帮助我，那会很棒。
提前谢谢您
HTML：{% block body %}

还有我的python脚本：from flask import Flask, render_template, url_for, request, redirect
from datetime import datetime
import sqlite3
from sqlite3 import Error
app = Flask(__name__)
# Here I create a DB and a connection
def create_connection(db_file):
connection = None;
try:
conn = sqlite3.connect(db_file)
print(sqlite3.version)
except Error as e:
print(e)
return conn
# This is were I call the function for my db
create_connection("gast.db")
# This is were I create the tables I want in the database
def create_table(conn, guests):
sql = """ INSERT INTO guests(voor_naam,achter_naam,bedrijfs_naam,datum)
VALUES(?,?,?,?) """
c = conn.cursor()
c.execute(sql,guests)
return cur.lastrowid
# here I insert the created tables
def main():
database = r"gast.db"
sql_create_guests_table = """ CREATE TABLE IF NOT EXISTS guests (
id integer PRIMARY KEY,
voor_naam text NOT NULL,
achter_naam text NOT NULL,
bedrijfs_naam text NOT NULL,
datum date NOT NULL
); """
conn = create_connection(database)
if conn is not None:
# maak gast table
create_table(conn, sql_create_guests_table)
else:
print("Error! cannot create the database connection.")
# index for the html page
@app.route('/')
def index():
return render_template("index.html")
# sending input form form to db
@app.route('/my_form', methods=['POST'])
def my_form():
if request.method == 'POST':
c = conn.cursor()
guest_vnaam = request.form.get('Voornaam')
guest_anaam = request.form.get('Achternaam')
guest_cnaam = request.form.get('Bedrijfsnaam')
guest_datum = request.form.get('Datum')
try:
sql = ("INSERT INTO databasename.tablename (columnName,columnName,columnName,columnName Ci) VALUES (%s, %s, %s, %s)")
c.execute(sql,(guest_vnaam, guest_anaam, guest_cnaam, guest_datum))
connection.commit()
#or "conn.commit()" (one of the two)
return redirect('/')
except:
return 'Er ging iets fout met het opslaan van uw gegevens'
# This is where I run the app
if __name__ == '__main__':
app.run(debug=True)
该应用程序运行，但是当我单击注册按钮时，出现以下错误：
文件“ /home/ronny/Desktop/registratieinc/app.py”，第70行，在my_form中c = conn.cursor()NameError：未定义名称'conn'
再次欢迎您提供任何帮助或建议(;
再次感谢！
