There's nothing wrong with the above code in principle. The problem
likely lies either in your render-form function, or your post-vote
function.
Try running the following routes:
(defroutes main-routes
(GET "/" [] "Main Page")
(GET "/form" []
(str "<form method='post' action='/vote'>"
"<input type='text' name='test'>"
"<input type='submit'>"
"</form>"))
(POST "/vote" {params :params}
(pr-str params))
(route/not-found "Page not found"))
If you go to "/form" and submit the form there, you should get a page
that looks something like:
{:test "foo"}
