RegexValidator for mobile number validation in Python

RegexValidator:-

A RegexValidator searches the provided value for a given regular expression with re.search(). By default, raises a ValidationError with message and code if a match is not found. Its behavior can be inverted by setting inverse_match to True, in which case the ValidationError is raised when a match is found.

class RegexValidator(regex=None

                                , message=None

                                , code=None

                                , inverse_match=None

                                , flags=0)

Parameters:-

regex à If not None, overrides regex. It can be a regular expression string or pre-compiled regular expression.

message à If not None, overrides message.

code à If not None, overrides code.

inverse_match à If not None, overrides inverse_match.

flags à If not None, overrides flags. In that case, regex must be a regular expression string, or TypeError is raised.

regex à The regular expression pattern to search for within the provided value, using re.search(). This may be a string or a pre-compiled regular expression created with re.compile(). Defaults to the empty string, which will be found in every possible value.

message à The error message used by ValidationError if validation fails. Defaults to "Enter a valid value".

code à The error code used by ValidationError if validation fails. Defaults to "invalid".

inverse_match à The match mode for regex. Defaults to False.

flags à The regex flags used when compiling the regular expression string regex. If regex is a pre-compiled regular expression, and flags is overridden, TypeError is raised. Defaults to 0.

Example:

mobile_number  = RegexValidator(regex="^[0-9]{10,15}$", message="Entered Mobile Number is not in right format..!")
