Autoload validation classes from Validator

[eaguad1337]

In docs, you could see something like this:

from masonite.validation import Validator
from masonite.validation import required, accepted
from masonite.request import Request
from masonite.response import Response

def show(self, request: Request, response: Response, validate: Validator):
    """
    Incoming Input: {
        'user': 'username123',
        'email': 'user@example.com',
        'terms': 'on'
    }
    """
    errors = request.validate(
        validate.required(['user', 'email']),
        validate.accepted('terms')
    )

    if errors:
        return response.back().with_errors(errors)

Specifically, this two lines will raise an error, because required and accepted are not attributes of Validator class. Instead, you should import the class from masonite.validation, but, in order to make it work more naturally, I propose this fix to make it work.

validate.required(['user', 'email']),
validate.accepted('terms')
