[BUG] docs don't show nested enum attribute for body

Describe the bug I have a post method with the body as pydantic object, with one attribute as Enum object; All validation works perfectly; However, two independent (?) issues occur:

1. complaint.dict() generates a dictionary - but does not flatten nested enum object into string. I am getting this is beyound the idea of dict(), but would be nice to have something that flattens the whole entity;
2. complaint_type attribute does not show up on the swagger

To Reproduce example coe snippet:

class ComplaintType(Enum):
    other = 'other'
    commercial = "commercial"
    house = "house"
    park = "park"
    residential = "residential"
    street = "street"
    vehicle = "vehicle"


class Complaint(BaseModel):
    complaint_type:ComplaintType
    timestamp:datetime = datetime.now()
    lat:float
    lon:float
    description:str

Expected behavior I expected

1. complaint_type to be on a swagger and in the schema as (I guess) “oneOf” element
2. be able to flatten Pydantic object into a fully json-able dictionary (converting enum objects into strings)

Environment:

• OS: macOS
• FastAPI Version 0.30.0
• Python version 3,7.3

Can you test whether this fixes it:

class Geoaccuracy(str, Enum):
    unknown = "unknown"
    latlng = "latlng"
    place = "place"
    city = "city"
    country = "country"

This works for me and correctly shows in SwaggerDocs. In your case, you’ve specified type Enum but not which type for Enum (looks like its str, too).

Thank you both! That makes a lot of sense - somehow I never used Enum before, so - good to know!
