def check_value(self):
self.status = True if self.field_value == 'test' else False
def check_null(self):
pass
# define a validator to use the rule
class TestRuleValidator(Validator):
name = 'test_rule'
# to run the validation

assert validator.validate()
```
custom a validation rule is very easy, you just import the BaseRule and implements the method ,
the most important thing is before you use your rule , you should pass it to your validator
class when it init through the extra_rules parameter.
