dicty 0.1

A library for mapping dictionaries to Python objects

Sample usage

With dicty you can easily describe your data model and then use it to encode/decode JSON objects. It supports data validataion, optional parameters, default values, nested objects and so on.

import dicty


class MyDoc(dicty.DictObject):
    prop1 = dicty.StringField()
    prop2 = dicty.IntegerField()

# Regular constructor
doc = MyDoc(prop1='foo', prop2=123)
print doc.prop1     # you can access values as attributes
print doc['prop2']  # as well as dictionary items

print json.dumps(doc)
print json.dumps(doc.jsonify()) # Jsonify will clean and validate output data

# Create instance from dictionary
doc = MyDoc.fromjson({'prop1': 'foo', 'prop2': 123})

# would raise dicty.FieldError here
doc = MyDoc.fromjson({'prop1': 123, 'prop2': 123})

Nested Objects

import dicty


class Foo(dicty.DictObject):
    class Bar(dicty.DictObject):
        prop = dicty.StringField()

    bar = dicty.TypedObjectField(Bar)

obj = Foo()
obj.bar.prop = 123
print obj # {'bar': {'prop': 123}}
