Rendering Flask-WTF forms in templates

To render the form, we first need to return it from a view to the template.

Modify login view in app.py

Now let’s modify the application module to use the forms.

Import LoginForm

Let’s first import the LoginForm from the forms module forms.py.

from forms import LoginForm

Create an object of LoginForm in the login view

We will then create an object of this form inside the login route.

@app.route("/login", methods=["GET", "POST"])
def login():
    form = LoginForm()

Return the form to the template

This form will be passed to the render_template function as a named argument.

return render_template("login.html", form = form)

Complete implementation of app.py

The complete implementation of the modified app.py is given below:
