compojure.handler behavior for redundant parameters

[Chris Dale]

Hello!

I thought I had read some place that compojure.handler's default behavior for a param string of the type ?foo=1&bar=2&foo=3 was to produce a map of the form {:foo [1 3] :bar 2}; however, I'm getting one of the form {:foo 3 :bar 2}. Was I misinformed? Has the code changed? Am I missing a configuration of some kind? Is this easy to enable, or am I to delve into the murky depths of implementing my own handler?

Thanks!

You likely have wrap-nested-params around your handler, which assumes a Rails-like syntax of "foo[]" for building nested maps and arrays.

However, Ring 1.2.2 will include a fix to ensure that wrap-nested-params won't affect keys without square brackets, so when that is released it will act as you expect.

Thanks you very much! Not to sound impatient, but when might that happen? Is this something where I can focus on other aspects of the site until this drops?

You can remove wrap-nested-params if you don't need it - which you don't if you're using "foo" and not "foo[]". I believe it's included in compojure.handler/site, but this is merely a convenience function. You can apply the middleware manually for finer control.

Ring 1.2.2 will likely be out at the end of this year, or at the beginning of 2014.

Thanks again! I love the process of coming to understand how to use the software you're working with, instead of relying upon an exposed API.

Well, it looks like I'm going to do it the foo[] way after all, and it is not entirely clear to me how to set that up, nor indeed do I know what to call it to look for it. Is this a job for cljs/js?

That is to say, are you saying the syntax it expects is foo=[bar,baz]?

You don't need to use wrap-nested-params if you don't want to. You only need it if you want Rails-like nested parameters. If you don't know what that is, chances are that you don't need it :)

Instead of using compojure.handler/site, apply the middleware you want manually to your application.
