Task challenge not passing. Help

Your register() view needs to create an instance of the SignUpForm from forms. It should also render and return the register.html template. You'll need to import render_template. In the template's context, name the SignUpForm instance as form.

lunch.py
from flask import Flask, g, render_template
from flask.ext.login import LoginManager

import forms
import models

app = Flask(__name__)
app.secret_key = 'this is our super secret key. do not share it with anyone!'
login_manager = LoginManager()
login_manager.init_app(app)


@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.route('/register', methods=('GET', 'POST'))
def register():
    return ("register")
    form = forms.SignUpForm
    return render_template('register.html', form=form)

@app.after_request
def after_request(response):
    g.db.close()
    return respo6nse
models.py
import datetime

from flask.ext.bcrypt import generate_password_hash
from flask.ext.login import UserMixin
from peewee import *

DATABASE = SqliteDatabase(':memory:')


class User(Model):
    email = CharField(unique=True)
    password = CharField(max_length=100)
    join_date = DateTimeField(default=datetime.datetime.now)
    bio = CharField(default='')

    class Meta:
        database = DATABASE

    @classmethod
    def new(cls, email, password):
        cls.create(
            email=email,
            password=generate_password_hash(password)
        )


def initialize():
    DATABASE.connect()
    DATABASE.create_tables([User], safe=True)
    DATABASE.close()
forms.py
from flask_wtf import Form
from wtforms import StringField, PasswordField
from wtforms.validators import DataRequired, Email, Length


class SignUpForm(Form):
    email = StringField(validators=[DataRequired(), Email()])
    password = PasswordField(validators=[DataRequired(), Length(min=8)])

Are you at Challenge task 2 of 3?

I tried the code (in lunch.py) and it passed for me:

from flask import Flask, g, render_template
from flask.ext.login import LoginManager

import forms
import models

app = Flask(__name__)
app.secret_key = 'this is our super secret key. do not share it with anyone!'
login_manager = LoginManager()
login_manager.init_app(app)


@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.route('/register', methods=('GET', 'POST'))
def register():
    form = forms.SignUpForm()
    return render_template('register.html', form=form)

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

Hi Noor

Not sure if you still need help but I looked at your code and spotted a few things:

  • remove this line in your register() view: return ("register")
  • you are missing a couple of parens here, also in your register() view, should be: form = forms.SignUpForm()
  • a small typo here, the very last line of your code, remove the '6': return respo6nse

I think you should pass the challenge after making these changes.

Hope this helps!
