Код Python (для formzxc) из flask_wtf import FlaskForm из wtforms import StringField, PasswordField, SubmitField, BooleanField, IntegerField из wtforms.validators import DataRequired, Length, Email, EqualTo
class Amount(FlaskForm):
purpose = StringField('Type:',
validators = [DataRequired(),Length(max =25)])
amount = IntegerField('Amount:',
validators = [DataRequired()])
submit = SubmitField('Submit!')
Следует ли использовать form.purpose.data вместо Amount.purpose.data при вызове Category? — person DemonicAoi schedule 30.12.2019
