Getting Rails route error instead of 404


(Philipp Rudloff) #1

Starting Discourse in development mode and opening http://localhost:3000/x doesn’t produce a 404 page like https://meta.discourse.org/x does. Instead, I get the Rails routing error page:

No route matches [GET] "/x"

I disabled the plugin I’m developing, but that doesn’t affect this problem.

Note that a link with href="/x" does produce the expected 404 error page, only a regular request doesn’t.

I’m not sure how to categorize this as I’m certain this must be an issue on my end, not a bug with Discourse.

I think that’s just how development mode works.

Yeah, that’s a Rails feature when used in development mode.
