Note. HTML5 widgets and fields are builtin of wtforms since 1.0.4. You should consider import them from wtforms if possible. However, wtforms missed a DateInput, which is why we still keep the html5 module.Once wtforms has a full feature of html5 forms, Flask-WTF will drop supporting for them dashboard.py. Instead of creating our dash_app object as a global variable (as is suggested), we stuck in a function called create_dashboard().This allows us to pass our top-level Flask app into Dash as server, hence dash_app = Dash(server=server).This effectively spins up a Dash instance using our Flask app at its core, as opposed to its own!. Take note of how we pass a value to routes. We use add_url_rule to register rule to handle /users/ url end point and we pass the class as view function which is done by as_view class method and we can refer this method in our Jinja2 templates using name users. So a statement like. url_for('users') in our templates will be converted to /users/ URL when page is rendered to client by Flask In this part of the series, we're going to scrape the contents of a webpage and then process the text to display word counts.
