How check if value exists in request POST? [duplicate]

Question

I submit form using POST method. Form has one input field: time.

I tried to check if exist parameter:

if 'time' in request.data:
   pass

But it does not work

Where are you submitting your form from? How are you receiving it? Where are you attempting to obtain the submitted data? So many questions... — zwer

I use Flask: @app.route('/schedule/<int:adv_id>', methods=['POST']) def schedule(adv_id): — Agella

The code that will handle your arguments can read in the time key by using either request.data.get('time') or request.data['time']. By calling request.data.get('time'), the application will continue to run if the language key doesn’t exist in the URL. In that case, the result of the method will be None. So you need t = request.data.get('time') if t: pass Source: digitalocean.com — JFM

You should use request.form if you're posting your data as a regular POST body query, i.e.:

@app.route('/schedule/<int:adv_id>', methods=['POST'])
def schedule(adv_id):
    if "time" in request.form:
        pass  # do whatever you want with it
