Describe the bug
before v0.38.0 allOf generates a class hierarchy, from v0.38.0 upwards (including latest 0.42.2) this is no longer the case.
To Reproduce
Example schema:
{
"$defs": {
"Thing": {
"title": "Thing",
"type": "object",
"required": [
"type",
"name"
],
"properties": {
"type": {
"type": "string",
"default": "playground:Thing",
"options": {
"hidden": true
}
},
"name": {
"type": "string",
"description": "The things name",
"minLength": 1,
"default": "A Thing"
}
}
}
},
"allOf": [
{
"$ref": "#/$defs/Thing"
}
],
"title": "Person",
"type": "object",
"required": [
"name"
],
"properties": {
"type": {
"$comment": "Already defined in playground:Thing -> we override just the default",
"default": "playground:Person"
},
"name": {
"description": "First and Last name",
"minLength": 4,
"default": "John Doe"
},
"age": {
"type": "integer"
}
}
}Used commandline:
datamodel-codegen--input schema.json --output model.py
Expected behavior
*** Result model.py for v0.37.0
class Thing(BaseModel):
type: str
name: constr(min_length=1) = Field(..., description='The things name')
class Person(Thing):
type: Optional[Any] = 'playground:Person'
name: Any = Field(..., description='First and Last name')
age: Optional[int] = None*** Result model.py for >=v0.38.0
