Colander
Colander is useful as a system for validating and deserializing data obtained via XML, JSON, an HTML form post or any other equally simple data serialization. Colander can be used to:
- Define a data schema.
- Deserialize a data structure composed of strings, mappings, and lists into an arbitrary Python structure after validating the data structure against a data schema.
- Serialize an arbitrary Python structure to a data structure composed of strings, mappings, and lists.
Colander is a good basis for form generation systems, data description systems, and configuration systems.
Out of the box, Colander can serialize and deserialize various types of objects, including:
- A mapping object (e.g. dictionary).
- A variable-length sequence of objects (each object is of the same type).
- A fixed-length tuple of objects (each object is of a different type).
- A string or Unicode object.
- An integer.
- A float.
- A decimal float.
- A boolean.
- An importable Python object (to a dotted Python object path).
- A Python
datetime.datetimeobject. - A Python
datetime.dateobject.
Colander allows additional data structures to be serialized and deserialized by allowing a developer to define new "types".
The error messages used by Colander's default types are internationalizable.
