    "last_name": "required|string|max:255",
    "password": "required|min:8|max:255"

    "last_name": "Doe",
    "password": "test1234"

validator = Validator()
errors = validator.validate(input_, rules)

Direct Validation

Sometimes there is a need for quick and simple validation, without having to create a rule set. The Validator class exposes several static methods that can be used for direct validation.

For example:

email = "john.doe@example.com"

if validator.valid_email(email):
    print("This is a valid email!")

# Or like this:

if Validator.valid_email(email):
    print("This is a valid email!")

Available methods:

  • valid_email
  • valid_url
  • valid_ip
  • valid_uuid4
  • valid_string
  • valid_integer
  • valid_boolean
  • valid_json
  • valid_list
  • valid_alpha_num
  • valid_alpha_num_space
