Hi i have a flask app with a react front end. Where the react htmls generated through npm build are rendered. I also want the react frontend to show these flash messages as per the conditions. But since the backend and frontend are not dynamically connected. What options do i have to resolve this issues ? Below i have sample code showing some of the conditions.
@user.route('/supervised', methods=['GET', 'POST'])
def supervised():
form = SubmitData()
if request.method == 'POST':
if 'file' not in request.files:
flash('No file part')
return redirect(request.url)
file = request.files['file']
try:
file2 = request.files['file2']
except werkzeug.exceptions.BadRequestKeyError:
file2 = None
if file.filename == '':
flash('No selected file')
return redirect(request.url)
if allowed_file(file.filename) is False:
flash('Please upload a .csv file for training dataset.')
return redirect(request.url)
flash('Message')
return render_template('support.html')
return render_template('supervised.html', form=form)
