dvConstraint = (XSSFDataValidationConstraint)validationHelper.CreateTimeConstraint(OperatorType.BETWEEN, "=TIME(0,0,0)", "=TIME(23,59,59)");

dvConstraint = (XSSFDataValidationConstraint)validationHelper.CreateExplicitListConstraint(new string[] { "MON", "TUE" , "WED", "THU", "FRI"});

Set SECKET_KEY, then flashing message in view function: from flask import Flask, flash, render_template app = Flask(__name__) app.secret_key = 'some_secret' @app.route('/') def index(): flash('Hello, I'm a message.') return render_template('index.html') Then render the messages...

Set second argument when use flash() in view function: flash('Something was wrong!', 'error') In the template, set with_categories=true in get_flashed_messages(), then you get a list of tuples in the form of (message, category), so you can use category as a HTML class. {% with messages = get_fl...
