You can already do something like this:
In your routes:
get "foo(.:format)(.:compression)" => "foo#index"
Then in your controller:
respond_to do |format|
format.xml do
if params[:compression] == "zip"
render ...
else
render ...
end
end
end
That being said a format of csv.zip is not `csv` since it is zipped and it is
not purely `zip` since that gives no indication of the actual contents of the
file. Having some kind of built in support for this would be expected by me if
I was trying this out for the first time.
Though if we were to add this feature I would expect it to be greedy so if you
visit `foo.csv.zip` it would first look for a `csv.zip` format and if that was
not found, it would look for a `csv` format as a backup. I haven't checked into
the implementation implications. If it is simple to implement with no
performance impact I would be :+1: otherwise it's not enough of a win as you
can already do something like this (as above).
If someone implements this cc/ me on the PR and I'll be happy to comment.
