Describe the bug
Hello, I've been unable to parse json within "$defs"
The json schema below is representative of the output from a call to Pydantic v2's models_json_schema. The resulting python model doesn't include the ArrayDataset model.
Replacing "$defs" with "definitions" gives the expected output.
To Reproduce
Example schema:
{
"$defs": {
"ArrayDataset": {
"description": "mini_schema",
"properties": {
"creation_datetime": {
"anyOf": [
{
"format": "date-time",
"type": "string"
},
{
"type": "null"
}
],
"default": null,
"title": "Creation Datetime"
},
"id": {
"anyOf": [
{
"type": "string"
},
{
"type": "null"
}
],
"default": null,
"title": "Id"
},
"schema_version": {
"anyOf": [
{
"type": "string"
},
{
"type": "null"
}
],
"default": null,
"title": "Schema Version"
},
},
"required": [],
"title": "mini_schema",
"type": "object"
}
},
"title": "Metadata Schema"
}
Actual Output:
# generated by datamodel-codegen:
# filename: mini_migration_schema.json
# timestamp: 2023-09-27T23:09:31+00:00
from __future__ import annotations
from typing import Any
from pydantic import Field, RootModel
class MetadataSchema(RootModel):
root: Any = Field(..., title='Metadata Schema')Used commandline:
$ datamodel-codegen --input mini_migration_schema.json --input-file-type jsonschema --output mini_migration_schema_v2.py --output-model-type pydantic_v2.BaseModel
Expected behavior
