Python Build a Social Network with Flask Tacocat Challenge Tacocat!

Tococat Challenge - Cheese shows as yes every time.

So I passed all the tests and completed the challenge just fine.

However, clearly there wasn't a test for this.

Everytime I make a new taco, it shows Cheese? - Yes . I've tried a few different things to get it to display the Cheese BooleanField correctly but I always get YES in the cheese field.

I will be seeking to figure this out on my own while I await a reply on this, but any help or insight would be appreciated.

NOTE: I have only included the code related to my Taco(Model) class and the rendering of it for the sake of not giving away the code challenge answer. Therefore, this code will not run as it has no imports or database. But I think everything necessary to the issue is there and should be enough for someone to see what I'm doing wrong.

tacocat.py 
@app.route('/taco', methods=('GET', 'POST'))
@login_required
def taco():
    form = forms.PostTacoForm()
    if form.validate_on_submit():
        models.Taco.create(user=g.user.id,
                           protein=form.protein.data,
                           cheese=form.protein.data,
                           shell=form.shell.data,
                           extras=form.extras.data.strip())
        flash("Taco Posted! Thanks!", "success")
        return redirect(url_for('index'))
    return render_template('taco.html', form=form)


@app.route('/')
def index():
    tacos = models.Taco.select().limit(100)
    return render_template('index.html', tacos=tacos)

    )
    protein = CharField(max_length=25)
    shell = CharField(max_length=25)
    cheese = BooleanField()
    extras = TextField()

Well I discovered in my '/taco' view that i had cheese = form.protein.data

DUH!

I remember doing that for some testing reason, and forgot to change it back.

Also, before making this discovery, i added to my cheese attribute in my PostTacoForm:

cheese = BooleanField('Cheese', false_values=('False', '', 'false', 'None'))

this may have been the ultimate fixer, but I couldn't see it until I discovered the view issue. Ha.
