Usage

Here’s a quick teaser of what you can do with peewee-validates:

import peewee
from peewee_validates import ModelValidator

class Category(peewee.Model):
    code = peewee.IntegerField(unique=True)
    name = peewee.CharField(null=False, max_length=250)

obj = Category(code=42)

validator = ModelValidator(obj)
validator.validate()

print(validator.errors)

# {'name': 'required field', 'code': 'must be unique'}

In fact, there is also a generic validator that does not even require a model:

from peewee_validates import Validator, Field

class SimpleValidator(Validator):
    name = Field(str, required=True, max_length=250)
    code = Field(str, required=True, max_length=4)

validator = SimpleValidator(obj)
validator.validate({'code': 'toolong'})

print(validator.errors)

# {'name': 'required field', 'code': 'must be at most 5 characters'}
