You need to render the template. Do you remember the name of the function that renders templates? To render the template, too, you need to pass it the form instance. Do you remember how to pass context variables to the templates?

Hello Thanitsak.

I have read your code and I found a lot of similarities with this forum thread. I will link it here, please have a look at it:

https://teamtreehouse.com/forum/register-view-so-that-the-form-is-validated-on-submission-if-its-valid-use-the-modelsusernew-method-to-create-a

I do think, you both guys experienced very similar struggles, so you may want to read it and if still something unclear please feel free to ask!

Thanks

Vittorio

Here my file!

from flask import (Flask, render_template, flash, g ) 
from flask.ext.login import LoginManager

import forms
import models

app = Flask(__name__)
app.secret_key = 'auoesh.bouoastuh.43,uoausoehuosth3ououea.auoub!'
login_manager = LoginManager()
login_manager.init_app(app)


@app.route('/register', methods=('GET', 'POST'))
def register():
    form = forms.SignUpForm()
    flash("Thanks for registering!", "success")
    if form.validate_on_submit():
      models.User.new(            
            email=form.email.data,
            password=form.password.data,

      return "register"
    return render_template('register.html', form=form)


@login_manager.user_loader
def load_user(userid):
    try:
        return models.User.select().where(
            models.User.id == int(userid)
        ).get()
    except models.DoesNotExist:
        return None


@app.before_request
def before_request():
    g.db = models.DATABASE
    g.db.connect()


@app.after_request
def after_request(response):
    g.db.close()
    return response

Look at your if. You're still just returning the word "register" if they successfully sign up. The challenge wants you to still render the template.

Also, your flash should be inside the if since you don't want to say "thanks for signing up" before they signed up.
