CerbeRedis
==========
.. image:: https://raw.githubusercontent.com/adamlwgriffiths/cerberedis/master/images/cerberedis.png
De/serialise `Cerberus <https://github.com/pyeve/cerberus>`_ data to a `Redis <http://redis.io/>`_ database.
Installation
------------
.. code-block:: bash
$ pip install cerberedis
Example
-------
A basic example:
.. code-block:: python
from cerberus import Validator, TypeDefinition
from redis import Redis
from cerberedis import CerbeRedis
schema = {
'name': {'type': 'string', 'required': True},
'email': {'type': 'string', 'required': True},
}
data = {'name': 'Bob', 'email': 'bob@example.com'}
# connect to our redis server
r = Redis()
db = CerbeRedis(r)
# save the schema under the type name 'User'
# with a document id of 1
model_name, id = 'User', 1
db.save(model_name, schema, id, document)
# print the key the model is stored under
print(db.key(model_name, id))
# reload the document
loaded_document = db.load(model_name, schema, id)
A full featured example, including custom types:
.. code-block:: python
from ipaddress import ip_address, IPv4Address, IPv6Address
from datetime import date, datetime
from cerberus import Validator, TypeDefinition
from redis import Redis
# alternatively use redis_mock (https://github.com/adamlwgriffiths/redis-mock)
# from redis_mock import Redis
from cerberedis import CerbeRedis
# Add custom types to both Cerberus
# https://docs.python-cerberus.org/en/stable/customize.html
Validator.types_mapping.update({
'ipaddress': TypeDefinition('ipaddress', (IPv4Address, IPv6Address), ()),
'ipv4address': TypeDefinition('ipv4address', (IPv4Address,), ()),
'ipv6address': TypeDefinition('ipv6address', (IPv6Address,), ()),
})
# Provide CerbeRedis with information on how to handle these new Cerberus types
CerbeRedis.rules.update({
# dictionary of: <cerberus type name>: [to redis function, from redis function]
'ipaddress': [lambda x: str(x), lambda x: ip_address(x.decode('utf-8'))],
'ipv4address': [lambda x: str(x), lambda x: IPv4Address(x.decode('utf-8'))],
'ipv6address': [lambda x: str(x), lambda x: IPv6Address(x.decode('utf-8'))],
})
# An example Cerberus schema that uses all the built-in Cerberus types
# and the custom ones we defined above
schema = {
'boolean': {'type': 'boolean', 'required': True},
'binary': {'type': 'binary', 'required': True},
'date': {'type': 'date', 'required': True},
'datetime': {'type': 'datetime', 'required': True},
'float': {'type': 'float', 'required': True},
'integer': {'type': 'integer', 'required': True},
'number': {'type': 'number', 'required': True},
'string': {'type': 'string', 'required': True},
'dict': {'type': 'dict', 'schema': {
'dict_a': {'type': 'string', 'required': True},
'dict_b': {'type': 'integer', 'required': True},
}},
'list': {'type': 'list', 'schema': {'type': 'integer'}},
'set': {'type': 'set', 'schema': {'type': 'string'}},
'ipv4address': {'type': 'ipv4address', 'required': True},
}
data = {
'boolean': True,
'binary': b'123',
'date': date.today(),
'datetime': datetime.now(),
'float': 1.23,
'integer': 456,
'number': 789.0,
'string': 'abcdefg',
'dict': {
'dict_a': 'dict_a_value',
'dict_b': 9999,
},
'list': [1,2,3,4,5],
'set': {'a', 'b', 'c'},
'ipv4address': IPv4Address('127.0.0.1'),
}
# Use cerberus to validate and normalise the data
validator = Validator(schema)
document = validator.normalized(data)
if not document:
raise ValueError(str(validator.errors))
# connect to our redis server
r = Redis()
db = CerbeRedis(r)
model_name, id = 'TestModel', 1
db.save(model_name, schema, id, document)
# reload the document
loaded_document = db.load(model_name, schema, id)
# verify the data is laid out how we expect
assert document == loaded_document
Supported Types
---------------
All existing `Cerberus Types <https://docs.python-cerberus.org/en/stable/validation-rules.html#type>`_:
* boolean
* binary
* date
* datetime
* float
* integer
* number
* string
* dict
* list
* set
Limitations
-----------
* Containers cannot be nested. Ie. lists and sets cannot contain lists, sets, or dicts.
Future Work
-----------
* Use a Redis Pipeline for the load function
Changelog

1.0.5
-----
* Return None rather than empty containers. Permits us to know if the value actually exists.
1.0.4
-----
* Fix image link
1.0.3
-----
* Fix handling of None values for non-required fields
1.0.2
-----
* Expose key function
1.0.1
