Here is my code:
class CreateUser(Form):
username = StringField('Username', [
validators.Regexp('\w+', message="Username must contain only letters numbers or underscore"),
validators.Length(min=5, max=25, message="Username must be betwen 5 & 25 characters")
])
password = PasswordField('New Password', [
validators.DataRequired(),
validators.EqualTo('confirm', message='Passwords must match')
])
confirm = PasswordField('Repeat Password')
So the problem exists at line 3. I want the username to be only alpha numeric characters. For some reason this regex is only checking the first character. Is there a reason why the + symbol is not working here? Thanks.
Replacing the regex with
'^\w+$'
solved the problem.
