python - Flask add DB entry using a form -

i'm beginner learning flask. i'm making app , i've created db model user, , html/ js form takes input. want use form information create new entry in database unsure on how it. tried

@app.route('/add_to_db') def add_to_db():     email = request.form['email']     activated = 0;     user = models.user(email= email, activated = 0)     db.session.add(user)     db.session.commit() 

html code:

<form onsubmit="return validateemail(document.getelementbyid('email').value)" action="{{ url_for("add_to_db") }}" method="post">     please input email adress: <input id="email">     <input type="submit"> </form> <script>     function validateemail(email) {         var re = /^([\w-]+(?:\.[\w-]+)*)@((?:[\w-]+\.)*\w[\w-]{0,66})\.([a-z]{2,6}(?:\.[a-z]{2})?)$/i;         return(re.test(email));     } </script> 

but gave me 405 method not allowed error.

a 405 error means "method not allowed". sending form data, using post request , need allow post requests. default requests allowed. change line @app.route('/add_to_db') @app.route('/add_to_db', methods=['post']).
