FastAPI code generator generating unhashable models when using an enum
Description
I am using enums with FastAPI (see code snippets below). As the code is generated by FastAPI, I do not have an idea on how to make the enum hashable. Is there something I can add to make the enums hashable?
FastAPI Version
0.110.2
Pydantic Version
1.10.15
Python Version
Python 3.9.13
Code snippets
DraftType:
type: string
enum:
- Type1
- Type2
- Type3which is generated to the following Python class:
class DraftType(str, Enum):
Type1 = "Type1"
Type2 = "Type2"
Type3 = "Type3"It is used in another type:
Draft:
type: object
properties:
draftType:
$ref: "#/components/schemas/DraftType"
version:
type: integer
format: int64
required:
- draftType
- versionThe classes are then used in the FastAPI app:
@async_http_exception
async def get_draft(
draft_request: DraftRequest = Body(None, description=""),
) -> None:
draft: Draft = DraftLoader.get_draft(draft_request=draft_request)class DraftRequest(BaseModel):
draft_type: DraftType = Field(alias="draftType")
DraftRequest.update_forward_refs()class DraftLoader:
...
@staticmethod
@lru_cache()
def get_draft(draft_request: DraftRequest) -> Draft:
...
# fetch latest draft version...
draft: Draft = ...
...
return draftHowever, the code raises an error when calling DraftLoader.get_draft:
E File "<!- some file path ->", line 46, in get_draft
E draft: Draft = DraftLoader.get_draft(draft_request=draft_request)
E TypeError: unhashable type: 'DraftRequest'How can I specify, that DraftRequest is generated to be hashable?
