In your /order route function order_lunch(), no argument is set for the order in models.LunchOrder.create().

Add: order=form.order.data

@app.route('/order', methods=('GET', 'POST'))
def order_lunch():
    form = forms.LunchOrderForm()
    if form.validate_on_submit():
        models.LunchOrder.create(
            user=g.user._get_current_object(),
            # HERE
            data=form.content.data.strip())

    return render_template('lunch.html', form=form)

Checking further, i noticed two other errors: an additional typo in your original code, and a grabbing the wrong data for 'date' from the form.

@app.route('/order', methods=('GET', 'POST'))
def order_lunch():
    form = forms.LunchOrderForm()
    if form.validate_on_submit():
        models.LunchOrder.create(
            user=g.user._get_current_object(),
            # Add missing line for 'order' argument
            order=form.order.data,
            # original line:
            # data=form.content.data.strip()
            # correct typo: replace 'data' with 'date'
            # correct form data for 'date'
            date=form.date.data,
            )

    return render_template('lunch.html', form=form)

This code as been tested against the challenge and passes Task 3.

Not passing still.... will just refresh and repeat several times, it works with quizzes and when opening a new workspace

By "not passing" are you referring to the associated code challenge?

If I use your original code for form.py it passes Task 1.

If I then use my lasted corrected code above, it passes Tasks 2 and 3. Not sure why you're having different results.

Done it now, repeated 4 times using the same code. This happens every other week in one way or another...
