Example Code

class DropdownOption(str, Enum):
    option_1 = "Option 1"
    option_2 = "Option 2"
    option_3 = "Option 3"

@app.get("/dropdown/{option}")
async def read_dropdown(option: DropdownOption):
    option_value = option.value  
    return {"selected_option": option_value}

Description

Is there someway for a dropdown in the fastapi docs to display text but have the url display the corrospoding integer value instead of the text? As you can see in the image below "Option 2" is selected and then the url displays "Option%202". Is there anyway that instead I could have the url just display "2" by somehow mapping Option1 to 1, Option2 to 2, and Option3 to 3? Thanks.

I don't have an answer for you but what you want is fast api to generate a oneOf for that field sorta like what is described in this stack over flow post https://stackoverflow.com/questions/66465888/how-to-define-enum-mapping-in-openapi

I am not really sure how to coax FastAPI in generating that format though.

That seems like it would work but yea I have no idea how to do this in fastapi. It just seems like that this would be something that is possible. ..
