Order_Lunch() Task 2of3: Didn't get a 200 on '/order'

I'm at a loss why the challenge is returning "Didn't get a 200 on 'order' " when I'm fairly sure my @app.route for '/order' is correct. Any suggestions where I went wrong?

Task 2 of 3 is to "Next, create a new view in lunch.py named order_lunch. Give it a route of /order and make sure it accepts both GET and POST methods. Make it return the rendered version of the lunch.html template."

forms.py
from flask_wtf import Form
from wtforms import StringField, PasswordField, TextAreaField, DateField
from wtforms.validators import DataRequired, Email, Length


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

class LunchOrderForm(Form):
    order = TextAreaField("Order", validators=[DataRequired()])
    date = DateField("Date", validators=[DataRequired()])
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(UserMixin, 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)
        )


class LunchOrder(Model):
    order = TextField()
    date = DateField()
    user = ForeignKeyField(User, related_name="orders")

def initialize():
    DATABASE.connect()

Hi Paul,

The reason it isn't passing is because you are trying to pass a form to the template, but you haven't defined a form in your view.

On the second task, it hasn't asked you to deal with the form submission yet, all you need to do is render the template. So you can leave out the "form=form".

@app.route('/order', methods=('GET', 'POST'))
def order_lunch():
    return render_template('lunch.html')
