There is a fine answer
on SO by @chrismccord about pleasant pattern-matching request format on controller actions, followed by a few comments saying that it does not work. Well - I checked - it doesn’t. A suggestion of digging into private fields of conn
instead unfortunately seems far less elegant. I assume this particular answer’s author knew what he was talking about In such case the param must have been removed at some point. And yes, I can imagine valid reasons for this removal but would like to know a) what was the actual rationale, and b) if there’s any replacement for this, other than mentioned in the comments to the answer (conn/private/phoenix_format) that could be used to pattern-match on controller actions?
