Since our current infrastructure runs with Multi Part Form data.

Through fast api.

input_spec = Multipart(model_name=Text(), model_version=Text(), prompt=Text(), numImages= Text(), height = Text(), width = Text())

@svc.api(input=input_spec, output=Image())

def txt2img(model_name : str, model_version: str, prompt: str, numImages: str, height : str, width : str):

inputData = InputConfig(

model_id = model_name,

model_version=model_version,

prompt = prompt,

numImages=int(numImages),

height = int(height),

width=int(width)

)

Consider this is the service.py file When I generate curl file from postman it gives me this curl --location '129.159.39.39:3001/txt2img' \ --form 'model_id="29"' \ --form 'model_versionadasdascxas="1"' \ --form 'num_images="RAW, analog style, A stunning portrait of a beautiful woman, plain white background, nbdy-scarlet-sd15, ((highly detailed skin, skin details)), sharp focus, paisley shirt, 8k UHD, DSLR, high quality, film grain, Fujifilm XT3, <"' \ --form 'prompt="30"' \ --form 'height="512"' \ --form 'width="512"' It works but it does not do key mapping. If you write "model_id" or "asdsa" as first element it will always map to model_id and the position of the arguments cannot be changed

And this is the way Fast Api takes inputs and work perfectly fine with postman, python multipart or anything @app.post("/model/{avc}/") async def model_abc(model_name: str, model_version: str = Form(), prompt: str = Form(), numImages: Union[int, None] = Form(None), height: Union[int, None] = Form(None), width: Union[int, None] = Form(None), initImage: Union[UploadFile,

And even I write anything in the first field it still maps it to model_name

If all names are defined, it will perform name mapping.

Thanks

@Muhammad Abdullah Rafique Hi. You can define optional values like normal Python function does. You just need to maintain them after all other args without default values.
