flask wtform TypeError: __init__() takes from 1 to 2 positional arguments but 3 were given

I am having troubles with form validation. The country list is generated correctly, and previous forms worked fine. It is only breaking in POST requests. Here is my forms.py: ``` from wtforms import Form, BooleanField, SelectField, \ StringField, PasswordField, SubmitField, validators, \ RadioField from ..models import User from pycountry import countries ... ## Account settings # We get all COUNTRIES COUNTRIES = [(c.name, c.name) for c in countries] # edit profile class ProfileForm(Form): username = StringField('name',[validators.Length(min=1, max=120), validators.InputRequired]) email = StringField('email', [validators.Length(min=6, max=120), validators.Email()]) company = StringField('name',[validators.Length(min=1, max=120)]) country = SelectField('country', choices=COUNTRIES) news = BooleanField('news') ``` and here is the view: ``` @user.route('/profile/', methods=['GET', 'POST']) @login_required def profile(): userid = current_user.get_id() user = User.query.filter_by(id=userid).first_or_404() print(user) form = ProfileForm(request.form) if request.method == 'POST' and form.validate(): user.username = form.username.data ... return render_template('settings.html', form=form ) else: form.username.data = user.username ... return render_template('settings.html', form=form ) ```
