How to fetch date from html form into flask

Question

I am trying to fetch date from html form into flask web application.

<input type="date" name="startdate">(html)

startdate = datetime.date(request.form['startdate'])(python-flask)

I am getting an error

File "C:\ProgramData\Anaconda3\lib\site-packages\werkzeug\datastructures.py", line 431, in getitem raise exceptions.BadRequestKeyError(key) werkzeug.exceptions.HTTPException.wrap..newcls: 400 Bad Request: KeyError: 'startdate'

start_date = request.values['startdate'] File "C:\ProgramData\Anaconda3\lib\site-packages\werkzeug\datastructures.py", line 1415, in __getitem__ raise exceptions.BadRequestKeyError(key) werkzeug.exceptions.HTTPException.wrap..newcls: 400 Bad Request: KeyError: 'startdate' Again it is throwing the same error — ronit yadav, May 04 '19 at 06:20

When you fetch date from input field (type=date), You will always receive date in string format (yyyy-mm-dd), and you can parse this directly as follows:

from datetime import datetime
startdate = datetime.datetime.strptime(
                     request.form['startdate'],
                     '%Y-%m-%d')
