WTForms QuerySelectMultipleField Not sending List

I am working on a Flask Application to do some event scheduling. I am having problems with WTForms QuerySelectMultipleField in my form.

forms.py

class EnterEvent(Form):
...
invitees = QuerySelectMultipleField('Invitees', query_factory=lambda:
                            models.User.query.order_by(models.User.name).all())

and in my init.py file where I parse the Form POST data. Just to test I tried to return request.form['invitees'] just to see what is passed. Eventually I want to validate the data and add it to my SQLite3 DB.

@app.route('/event', methods=['POST', 'GET'])
def addEvent():
    form = EnterEvent()
    if request.method == 'POST':
        ...
        invitees = request.form['invitees']
        return invitees

the WTForm docs say that the QuerySelectMultipleField should return a list with ORM model instances but when I parse the POST request I am not getting a list. I checked the POST data in my browser and it looks like when I select multiple objects it is sending more than one.

I can't seem to figure this out. Any help will be greatly appreciated!

You would get your ORM model instances if you query your form object directly, rather then the 'raw' form data that's part of the request object

Assuming you're using Flask-WTF with it's little helpers built it, your invitees line should really read invitees = form.invitees.data.
