Booby is a standalone data modeling and validation library written in Python. Booby is under active development (visit this blog post for more info and the roadmap) and licensed under the Apache2 license, so feel free to contribute and report errors and suggestions.
See the sample code below to get an idea of the main features.
from booby import Model, fields
class Token(Model):
key = fields.String()
secret = fields.String()
class Address(Model):
line_1 = fields.String()
line_2 = fields.String()
class User(Model):
login = fields.String(required=True)
name = fields.String()
email = fields.Email()
token = fields.Embedded(Token, required=True)
addresses = fields.Collection(Address)
jack = User(
login='jack',
name='Jack',
email='[email protected]',
token={
'key': 'vs7dfxxx',
'secret': 'ds5ds4xxx'
},
addresses=[
{'line_1': 'Main Street'},
{'line_1': 'Main St'}
]
)
if jack.is_valid:
print jack.to_json(indent=2)
else:
print json.dumps(dict(jack.validation_errors))
{
"email": "[email protected]",
"login": "jack",
"token": {
"secret": "ds5ds4xxx",
"key": "vs7dfxxx"
},
"name": "Jack",
"addresses": [
{
"line_1": "Main St",
"line_2": null
},
{
"line_1": "Main Street",
"line_2": null
}
]
}
