colander 0.5.1

A simple schema-based serialization and deserialization library

Colander

An extensible package which can be used to:

• deserialize and validate a data structure composed of strings, mappings, and lists.

• serialize an arbitrary data structure to a data structure composed of strings, mappings, and lists.

Please see http://docs.repoze.org/colander for further documentation.

Changes

0.5.1 (2010-04-02)

• The constructor arguments to a the colander.Schema class are now sent to the constructed SchemaNode rather than to the type it represents.

• Allow colander.Date and colander.DateTime invalid error messages to be customized.

• Add a pos argument to the colander.Invalid.add method.

• Add a __setitem__ method to the colander.Invalid class.

• The colander.Mapping constructor keyword argument unknown_keys has been renamed to unknown.

• Allow colander.Mapping type to accept a new constructor argument: partial.

• New interface methods required by types and schema nodes: pserialize and pdeserialize. These partially serialize or partially deserialize a value (the definition of “partial” is up to the type).

0.5 (2010-03-31)

• 0.4 was mispackaged (CHANGES.txt missing); no code changes from 0.4 however.

0.4 (2010-03-30)

• Add colander.DateTime and colander.Date data types.

• Depend on the iso8601 package for date support.

0.3 (2010-03-29)

• Subnodes of a schema node are now kept in the children attribute rather than the nodes attribute.

• Add an sdefault property to colander.SchemaNode objects.

• Add a clone method to colander.SchemaNode objects.

• Add a __str__ method to the colander.Invalid exception that prints an error summary.

• Various error message improvements.

• Add colander.Length validator class.

0.2 (2010-03-23)

• Make nodetype overrideable.

• Add __getitem__ to SchemaNode.

• Fix OneOf message.

• Capitalize node titles.

• Deal with empty strings in String, Boolean, and Float types.

• Introduce description; make title the same as name.

• Remove copy method from schemanode.

• Allow schema nodes to have titles.

• The term “structure” is too overloaded to use for schema purposes: structure -> schema node.

• Make Sequence more like Tuple and Mapping (it uses a substructure rather than a structure parameter to denote its type).

• Add __repr__ and copy methods to structure.

• Add accept_scalar flag to Sequence.

0.1 (2010-03-14)

• Initial release.
