Question

我是Flask的新手，我遇到了这个问题：

使用此代码，我使用表单和IU在“/”indexv2.html上收费。我用表格更改了std，avg等不同的参数。我使用python创建预测模拟，并将此预测存储在文件中。 indexv2.html阅读此文件并显示可视化。我第一次这样做时效果很好并且显示正确的可视化，第二次它运行良好，存储文件很好，可视化仍然在前面，如果我重新加载页面，可视化改变为正确的可视化。如何重新加载页面才能正确查看？

sim.py

from flask import Flask, render_template, request, redirect
import forecast
import time

app = Flask(__name__)

@app.route('/')
def student():
   return render_template('indexv2.html')

@app.route('/result',methods = ['POST', 'GET'])
def result():
   if request.method == 'POST':
      result = request.form
      avg=result["Avg"]
      std=result["Std"]
      leadTime=result["leadTime"]
      sl=result["serviceLevel"]
      numDays=result["numdays"]
      forecastSimulation = forecast.Forecast(float(avg), float(std), float(leadTime), float(sl), int(numDays))
      print avg, std, leadTime, sl, numDays
      forecastSimulation.runAnalysis()

      return render_template("indexv2.html",result = result)

if __name__ == '__main__':
    app.run(debug = True, threaded=True)

indexv2.html
