You can't provide multiple regex's to the RegexField. What you were doing
before is exactly equivalent to this:
r'^.*(?=.{8,})(?=.*\d)(?=.*[a-z])(?=.*[A-Z])(?=.*[!$%^&*?@#-_+=]).*$'
So for my suggestion, just do this:
regex_f=r'^.*(?=.{{{MIN},{MAX}}})(?=.*\d)(?=.*[a-z])(?=.*[A-Z])(?=.*[!$%^&*?@#-_+=]).*$'
But the "^.*" and the ".*$" are not needed since RegexField uses
RegexValidator, which uses re.search().
