How can I do redirect 301 http in a Compojure/Luminus app?

I have an action in an Compojure/Luminus app:

(defn my-page1 [id]
  (layout/render "my_page.html" 
    (let 
      [item (db/get-single-item {:id id})]

      ; this throws an exception
      ; if .....
      ; redirect "fdsfdsfd" :status 301

      { :my-item item})))

How can I check some condition and if it's true, then do a redirect to a new url with the http status 301? Where should I put in the my code and how can I do a redirect?

Solution

  • Your layout/render function returns a full HTTP 200 ring response with HTML body content. You need to return a redirect response instead of the response produced by layout/render function:

    (defn my-page1 [id]
  (if (some-condition)
    (layout/render ...)
    (ring.util.response/redirect "http://elsewhere.com/" 301)))
