Project description

A simple and flexible model and data validator for Peewee ORM.

Build Status Code Coverage Version Downloads Documentation

Requirements

  • python >= 3.3
  • peewee >= 2.8.2 (including Peewee 3)
  • python-dateutil >= 2.5.0

Installation

This package can be installed using pip:

pip install peewee-validates

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': 'This field is required.', 'code': 'Must be a unique value.'}

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

from peewee_validates import Validator, StringField

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

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

print(validator.errors)

# {'name': 'This field is required.', 'code': 'Must be at most 5 characters.'}
