jsonschema

|
==========
|
|
|
|
``jsonschema`` is an implementation of `JSON Schema <http://json-schema.org>`_
|
|
for Python (supporting 2.6+ including Python 3).
|
|
|
|
.. code-block:: python
|
|
|
|
>>> from jsonschema import validate
|
|
|
|
>>> # A sample schema, like what we'd get from json.load()
|
|
>>> schema = {
|
|
... "type" : "object",
|
|
... "properties" : {
|
|
... "price" : {"type" : "number"},
|
|
... "name" : {"type" : "string"},
|
|
... },
|
|
... }
|
|
|
|
>>> # If no exception is raised by validate(), the instance is valid.
|
|
>>> validate({"name" : "Eggs", "price" : 34.99}, schema)
|
|
|
|
>>> validate(
|
|
... {"name" : "Eggs", "price" : "Invalid"}, schema
|
|
... ) # doctest: +IGNORE_EXCEPTION_DETAIL
|
|
Traceback (most recent call last):
|
|
...
|
|
ValidationError: 'Invalid' is not of type 'number'
|
|

Features
|
|
--------
|
|
|
|
* Full support for
|
|
`Draft 3 <https://python-jsonschema.readthedocs.org/en/latest/validate/#jsonschema.Draft3Validator>`_
|
|
**and** `Draft 4 <https://python-jsonschema.readthedocs.org/en/latest/validate/#jsonschema.Draft4Validator>`_
|
|
of the schema.
|
|
|
|
* `Lazy validation <https://python-jsonschema.readthedocs.org/en/latest/validate/#jsonschema.IValidator.iter_errors>`_
|
|
that can iteratively report *all* validation errors.
|
|
|
|
* Small and extensible
|
|
|
|
* `Programmatic querying <https://python-jsonschema.readthedocs.org/en/latest/errors/#module-jsonschema>`_
|
|
of which properties or items failed validation.
|
|
|
|
|
|
Release Notes
|
|
-------------
|
|
|
|
* A simple CLI was added for validation
|
|
* Validation errors now keep full absolute paths and absolute schema paths in
|
|
their ``absolute_path`` and ``absolute_schema_path`` attributes. The ``path``
|
|
and ``schema_path`` attributes are deprecated in favor of ``relative_path``
|
|
and ``relative_schema_path``\ .
|
|
|
|
*Note:* Support for Python 3.2 was dropped in this release, and installation
|
|
now uses setuptools.
|
|
|

|
Running the Test Suite
|
|
----------------------
|
|
|
|
If you have ``tox`` installed (perhaps via ``pip install tox`` or your
|
|
package manager), running``tox`` in the directory of your source checkout will
|
|
run ``jsonschema``'s test suite on all of the versions of Python ``jsonschema``
|
|
supports. Note that you'll need to have all of those versions installed in
|
|
order to run the tests on each of them, otherwise ``tox`` will skip (and fail)
|
|
the tests on that version.
|
|
|
|
Of course you're also free to just run the tests on a single version with your
|
|
favorite test runner. The tests live in the ``jsonschema.tests`` package.
|
|
