我爲如下時間字段定義wtforms:WTForms日期時間字段的時間沒有更新

stime = DateTimeField(label='Start time',validators=[validators.InputRequired()],format = "%d%b%Y %H:%M",default= datetime.now(timezone('UTC'))) 
    etime = DateTimeField(label='End time',validators=[validators.InputRequired()],format = "%d%b%Y %H:%M",default= datetime.now(timezone('UTC'))) 

在HTML頁面調用下面這個字段:

<form method= POST action="{{ url_for('input_ext') }}"> 
      <table> 
       {% for field in form %} 
       <tr> 
          <td>{{ field.label }}*</td><td>{{ field }}</td> 
       </tr> 
       {% endfor %} 
      </table> 
<input id = "generate" name="generate" type=submit value=Next></form> 

瓶代碼:

from flask import Flask 
from flask import render_template 
from flask import request 
from model import InputForm 

app = Flask(__name__) 
@app.route('/',methods = ['GET','POST']) 
#select interface and for selected interfaces pullup circuit info 
def provideinput(): 
    global devices 
    devices = '' 
    form = InputForm(request.form) 
    return render_template("utctime.html", form=form) 
if __name__ == "__main__": 
    app.run(debug=True,host="10.23.102.116",port=82) 

問題是,我得到UTC的時間,並沒有更新到當前UTC值,只要我重新加載page.It保持相同我開始運行Python代碼。 定義DateTimeField有什麼錯誤?

爲如下,仍然沒有運氣:

stime = DateTimeField(label='Start time(EDT)', validators=[validators.InputRequired()], format="%d%b%Y %H:%M", 
          default=datetime.today) 
    etime = DateTimeField(label='End time(EDT)', validators=[validators.InputRequired()], format="%d%b%Y %H:%M", 
          default=datetime.today) 
+0

ETIME = DateTimeField字段(標記= '結束時間(EDT)',驗證器= [validators.InputRequired()],格式=「%d%B%Y%H:% M「, 默認值= datetime.today) - >像這樣仍然是相同的沒有改變後重新加載 – ajay

答案是wtforms+flask today's date as a default value

有人援引這點。我不好,我在錯誤的地方編輯。

更改爲:

stime = DateTimeField(label='Start time(EDT)',validators=[validators.InputRequired()],format = "%d%b%Y %H:%M",default= datetime.utcnow) 
    etime = DateTimeField(label='End time(EDT)',validators=[validators.InputRequired()],format = "%d%b%Y %H:%M",default= datetime.utcnow)
