Question

我试图以表格形式输入值并从数据库中获取值，但我无法做到这一点。我正在使用名为travel的mysql数据库，并将表也命名为travel。我在下面附加了我的python代码和模板我的错误是：werkzeug.exceptions.BadRequestKeyError werkzeug.exceptions.HTTPException.wrap..newcls：400错误的请求：KeyError：'stay'

Python代码：

from flask import Flask, render_template, request, redirect,flash,url_for,session
from flask_mysqldb import MySQL
import datetime
import time
app = Flask(__name__)
app.config['MYSQL_HOST'] = "127.1.1.0"
app.config['MYSQL_USER'] = "root"
app.config['MYSQL_PASSWORD'] = "****"
app.config['MYSQL_DB'] ="travel"
app.secret_key="gsabo"
mysql = MySQL(app)
@app.route('/')
@app.route('/questions',methods=['GET', 'POST'])
def questions():
    if request.method == "POST" or "GET":
        userDetails= request.form
        cur = mysql.connection.cursor()
        stay=userDetails['stay']
        Budget=userDetails['Budget']
        print(Passengers,Weather,Transport,stay,Interests)
        cur.execute("select * from travel where stay=%s,Budget=%s",(stay,Budget,))
        mysql.connection.commit()
        userDetails=cur.fetchone()
        Location=userDetails[3]
        Budget=userDetails[4]
        return render_template('questions.html',Budget=Budget,Location=Location)
    return render_template('questions.html')
if __name__ == '__main__':
    app.run(debug=True)

HTML模板：

<html>
    <head>
    <meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
    <title>Travel</title>
    </head>
<body>
<div id="content">

                <tr>

                    <td><select name="Budget">

                </tr>

                    <td><input type="submit" value="Submit" href="hello" /></td>
                    <td><input type="reset" value="Reset" /></td>  
                </tr>  
        <tr>  
                    <td>Budget:</td>  
                    <td><input type="number" name="Budget" value="<%=Budget %>" readonly disabled/></td>  
                </tr> 
                <tr>  
                    <td>Location:</td>  
                    <td><input type="text" name="Location" value="<%=Location %>" readonly disabled/></td>

Answer 1

<td><select name="stay">
                        <option>Select</option>
            <option value="Hotel">Hotel</option>
            <option value="Tent">Tent</option>
            </select></td>

您具有此代码块，大概可以使用value = "Hotel"或value = "Tent"到/ questions，但在代码中仅占value = "stay"。您需要考虑所有情况
