Escriba error al llamar validar en wtforms

Question

Tengo TypeError en línea donde llamo ''validate ()'' en mi formulario.

El error es:

Mi código:

@app.route("/process_field", methods=[''POST''])
def process_field():
file = request.files[''upload'']
filled_form = FieldFootball(request.form)
if filled_form.validate():
filename = secure_filename(file.filename)
file.save(os.path.join(app.config[''UPLOADS_FOLDER''], filename))
doc = {"organization": filled_form.org_name.data, "address": filled_form.address.data,
"filename": filename, "price": filled_form.price.data, "phone": filled_form.phone.data,
"phone1": filled_form.phone1.data, "phone2": filled_form.phone2.data, "user_id": current_user.dic[''_id'']}
field = Field(doc)
field.save()
return redirect(url_for(''field_profile'', id=field.id))
else:
return render_template("add_field.html", form=filled_form)
class FieldFootball(Form):
org_name = TextField(u''Название организации'', [validators.Required])
address = TextAreaField(u''Полный адрес футбольного поля'',[validators.Required])
upload = FileField(u''Фотографии футбольного поля'', validators=[
FileRequired(),
FileAllowed([''jpg'', ''png''], u''Только фотографии!'')
])
price = TextField(u''Цена'', [validators.Required, validators.NumberRange])
phone = TextField(u''Телефоны'', [validators.Required])
phone1 = TextField(u'''')
phone2 = TextField(u'''')
my_choices = [(''1'', u''Трава''), (''2'', u''Крытый''), (''3'', u''Трибуны'')]
list_tags = MultiCheckboxField(choices = my_choices)

Es un poco raro porque lo usé en el controlador anterior, y va sin ningún argumento.

Por favor, ayúdame a resolverlo.

Necesita crear instancias de sus validadores:

org_name = TextField(u''Название организации'', [validators.Required()])

Tenga en cuenta el () después de Required ; esto se aplica a todos sus validadores. La instancia se llama nuevamente para validar la entrada.
