JSL
Documentation | GitHub | PyPI
JSL is a Python DSL for defining JSON Schemas.
Example
from jsl import Document, StringField, ArrayField, DocumentField, OneOfField
class Entry(Document):
name = StringField(required=True)
class File(Entry):
content = StringField(required=True)
class Directory(Entry):
content = ArrayField(OneOfField([
DocumentField(File, as_ref=True),
DocumentField('self') # recursion
]), required=True)Directory.to_schema() will return the following schema:
{
"$schema": "http://json-schema.org/draft-04/schema#",
"definitions": {
"module.File": {
"type": "object",
"additionalProperties": false,
"required": [
"content",
"name"
],
"properties": {
"content": {"type": "string"},
"name": {"type": "string"}
}
},
"module.Directory": {
"type": "object",
"additionalProperties": false,
"required": [
"content",
"name"
],
"properties": {
"content": {
"type": "array",
"items": {
"oneOf": [
{"$ref": "#/definitions/module.File"},
{"$ref": "#/definitions/module.Directory"}
]
}
},
"name": {"type": "string"}
}
}
},
"$ref": "#/definitions/module.Directory"
}Installing
