Generates patch by comparing of two document objects. Actually is a proxy to JsonPatch.from_diff() method.

python-json-patch is a Python library for applying JSON patches (RFC 6902). Python 2.7 and 3.4+ are supported. Tests are run on both CPython and PyPy. Contents · Tutorial · Creating a Patch · Applying a Patch · The jsonpatch module · Commandline Utilities ·

If you need to refer to a key with ~ or / in its name, you must escape the characters with ~0 and ~1 respectively. For example, to get "baz" from { "foo/bar~": "baz" } you’d use the pointer /foo~1bar~0.

library to apply JSON patches - Python 3.x

>>> obj = {'foo': 'bar'} # from a patch string >>> patch = '[{"op": "add", "path": "/baz", "value": "qux"}]' >>> res = jsonpatch.apply_patch(obj, patch) # or from a list >>> patch = [{'op': 'add', 'path': '/baz', 'value': 'qux'}] >>> res = jsonpatch.apply_patch(obj, patch) Custom JSON dump and load functions can be used to support custom types such as decimal.Decimal. The following examples shows how the simplejson package, which has native support for Python's Decimal type, can be used to create a custom JsonPatch subclass with Decimal support:

For example: [ JSONPatch{ op: &quot;add&quot;, path: &quot;/spec/selector&quot;, value: Object.spec.selector{matchLabels: {&quot;environment&quot;: &quot;test&quot;}} } ] To use strings containing '/' and '
