Here's my thought on 💭 fastapi https url_for

jinja's url_for in fastapi does not account for https by default, there is probably a better way, but this is a way that allows me to configure when I use http vs https.

def https_url_for(context: dict, name: str, **path_params: Any) -> str:
    always convert http to https
    request = context["request"]
    http_url = request.url_for(name, **path_params)
    return str(http_url).replace("http", "https", 1)

def get_templates(config: BaseSettings) -> Jinja2Templates:
    templates = Jinja2Templates(directory="templates")
    templates.env.globals["https_url_for"] = https_url_for

    ## only use the default url_for for local development, for dev, qa, and prod use https
    if os.environ.get("ENV") in ["dev", "qa", "prod"]:
        templates.env.globals["url_for"] = https_url_for
        console.print("Using HTTPS")
        console.print("Using HTTP")

    return templates
