我想用Flask構建一個預測Web應用程序。該應用程序應該接受用戶輸入,通過python訓練過的模型進行處理,然後在輸入表單旁顯示結果作爲圖表。如何根據表單輸入更新現有的Python Flask網頁?

我的代碼如下所示:

HTML表單:

<form class = "prediction-options" method = "post" action = "/prediction/results"> 
    <!--the input fields--> 
</form> 

瓶app.py

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

@app.route("/prediction/results", methods = ['POST']) 
def predict(): 
    input_aqi = float(request.form['aqi'])/272 
    input_pm2_5 = float(request.form['pm2_5'])/224 
    input_pm10 = float(request.form['pm10'])/283 
    input_so2 = float(request.form['so2'])/36 
    input_no2 = float(request.form['no2'])/110 
    input_co = float(request.form['co'])/1.83 
    input_o3 = float(request.form['o3'])/124 
    input_list = [[input_aqi,input_pm2_5,input_pm10,input_so2,input_no2,input_co,input_o3]] 


    output_acute_bronchitis = model_acute_bronchitis.predict(input_list) 
    output_asthma = model_asthma.predict(input_list) 
    output_asthmatic_bronchitis = model_asthmatic_bronchitis.predict(input_list) 
    output_aurti = model_aurti.predict(input_list) 
    output_bronchitis = model_bronchitis.predict(input_list) 
    output_pneumonia = model_pneumonia.predict(input_list) 

    d = collections.OrderedDict() 
    d['acute_bronchitis'] = output_acute_bronchitis[0] 
    d['asthma'] = output_asthma[0] 
    d['asthmatic_bronchitis'] = output_asthmatic_bronchitis[0] 
    d['aurti'] = output_aurti[0] 
    d['bronchitis'] = output_bronchitis[0] 
    d['pneumonia'] = output_pneumonia[0] 

    prediction = jsonify(d) 
    return prediction 

現在,我已成功地採取用戶在「/預測/結果」頁面上輸入並呈現預測結果。我怎樣才能讓結果顯示在'/'頁面上?我試圖做到這一點:

@app.route("/", methods = ['POST','GET']) 
def main(): 
    if request.method == 'POST': 
     def predict(): 
      #predict function that returns prediction 
    return render_template('index.html') 

但我總是得到一個socket.error: [Errno 32] Broken pipe錯誤消息。我該怎麼辦?

您可以在predict航線使用這個session,最後一行之前,預測存儲與

session['prediction'] = prediction 

然後你就可以在你的應用程序的任何其他途徑獲得,例如,你可以有這適用於/

@app.route("/", methods = ['POST','GET']) 
def main(): 
    if request.method == 'POST': 
     pass 

    prediction = session['prediction'] 

    return render_template('index.html', prediction=prediction)
