How can I handle empty strings as input on my FastAPI form?-CodePudding

@router.post('/update_attributes/{username}')
def update_attributes(request: Request, username: str, email: str = Form(...)):
    pass

How can I handle empty strings as input on my form? I get errors if the email textfield on my form is not filled in.

CodePudding user response：

The ellipses (...) means it is required. So leaving it empty would result in errors. If you want it not to be required, you can replace the ellipses with None like so:

@router.post('/update_attributes/{username}')
def update_attributes(request: Request, username: str, email: str = Form(None)):
    pass
