NOTE: This library does not yet have a stable API. It is a prototype only still, and not intended for anything resembling production use.
marshmallow-jsonschema translates marshmallow schemas into JSON Schema Draft v4 compliant jsonschema. See http://json-schema.org/
What are the use cases for this? Let's say you have a marshmallow schema in python, but you want to render your schema as a form in another system (for example: a web browser or mobile device).
from marshmallow_jsonschema import dump_schema
from tests import UserSchema
u = UserSchema()
dump_schema(u)Yields:
