Method Override Middleware
HTML forms only support GET and POST, but RESTful routing needs PUT, PATCH, and DELETE. Without method override, every destructive action would need a JavaScript fetch call or a POST route with an action parameter — neither is acceptable for progressive enhancement. This middleware lets forms submit any HTTP method via a hidden _method field.
Values
pub fn run(
ctx: context.Context(app),
next: fn(context.Context(app)) -> response.Response(wisp.Body),
) -> response.Response(wisp.Body)Applied before routing so the router sees the overridden method and matches the correct handler. Transforming the request before passing it down means every downstream middleware and handler sees the intended method without needing to check the _method field themselves.
