烧瓶从字段中保存选定的值并在另一页上显示

我是新来的烧瓶，并且遇到困难，保存从四种不同的咖啡烘焙选项中选择的值并将其显示在另一页上。一个页面（Roast.html）用户可以选择从Light，Medium，Dark和Special中选择一个咖啡烘焙。按下提交按钮后，我想在下一页（Brew.html）上显示该选择，即“你的_____烘焙咖啡现在正在酿造！”任何帮助将不胜感激！我宁愿不在这个代码中涉及php或javascript。谢谢烧瓶从字段中保存选定的值并在另一页上显示

coffeeMaker.py：

from flask import render_template 
from flask import url_for 
from flask import request 

app = Flask(__name__) 

@app.route('/') 
def welcome(): 
    return render_template("welcome.html") 

@app.route('/Roast', methods = ['GET','POST']) 
def roast(): 
    print "inside Roast" 
    return render_template("Roast.html") 

@app.route('/Brew', methods = ['GET','POST']) 
def brew(): 
    if request.method == 'POST': 
     print 456 
     a = request.query_string 
     print 789 
     return render_template("Brew.html",selection = a) 
    else: 
     return "This is a GET request." 



if __name__ == '__main__': 
    app.run()

你只需要从request.form对象抢元素：

if request.method == 'POST': 
    brew_type = request.form["roastType"] 
    print(brew_type) 
    return render_template("Brew.html", selection=brew_type)

它涵盖的所有quickstart guide。
