[hunchentoot-devel] Need some help figuring out what I'm doing wrong trying to get post parameters passed properly
I'm a Lisp newbie trying to use the jquery ui sortable widget ( http://api.jqueryui.com/sortable/) to sort a list of tasks. The plugin posts the list of tasks as:
1. task[]: 37 2. task[]: 36 3. task[]: 38
Which Hunchentoot sees as: [2013-02-09 11:15:34 [DEBUG]] parameters ((task[] . 37) (task[] . 36) (task[] . 38))
However, when I use this handler: (define-easy-handler (task-prioritize-url-handler :uri *task-prioritize*) (tasks) (task-prioritize tasks))
I get: [2013-02-09 11:38:52 [DEBUG]] task-prioritize NIL
[2013-02-09 11:38:52 [DEBUG]] parameters ((task[] . 36) (task[] . 38) (task[] . 37))
If I use: (define-easy-handler (task-prioritize-url-handler :uri *task-prioritize*) ((tasks :parameter-type 'array)) (task-prioritize tasks)) I get: [2013-02-09 11:36:07 [DEBUG]] task-prioritize #()
[2013-02-09 11:36:07 [DEBUG]] parameters ((task[] . 37) (task[] . 36) (task[] . 38))
If I use: (define-easy-handler (task-prioritize-url-handler :uri *task-prioritize*) ((tasks :parameter-type 'list)) (task-prioritize tasks)) I get: [2013-02-09 11:37:32 [DEBUG]] task-prioritize NIL
[2013-02-09 11:37:32 [DEBUG]] parameters ((task[] . 37) (task[] . 36) (task[] . 38))
My understanding from the documentation is that I should end up with a list of id's in the var task when is all said and done. Could someone tell me what I'm doing wrong that that isn't happening? Or help clarify my understanding?
Thanks so much!
the parameter name is "task[]", not "tasks" used as a default name for the 'tasks' parameter in the easy handler.

Fixed that, and it didn't work. I went through all three permutations (define-easy-handler (task-prioritize-url-handler :uri *task-prioritize*) ((task :parameter-type 'list)) (task-prioritize task))
results in: [2013-02-09 12:18:40 [DEBUG]] task-prioritize NIL

You're still not using the parameter name "task[]".
Try: (define-easy-handler (task-prioritize-url-handler :uri *task-prioritize*) ((task[] :parameter-type 'list)) (task-prioritize task[]))

that worked. It never hit me that the name of the variable could include the square brackets. Very cool! Thanks!

You may be able to use something like the following (untested):
(hunchentoot:define-easy-handler (task-prioritize-url-handler :uri *task-prioritize*) () (let ((tasks (mapcar #'cdr (remove-if-not (lambda (x) (string= (car x) "task[]")) (hunchentoot:get-parameters*))))) (task-prioritize tasks)))
If your request use "POST", you may have to replace get-parameters* with post-parameters*, or possibly to have both combined with append.

Not really relevant to the problem, just some "protips":
(remove-if-not (lambda (x) (string= (car x) "task[]")) (hunchentoot:get-parameters*)) => (remove "task[]" (hunchentoot:get-parameters*) :key #'car :test #'string/=)
But with mapcar #'cdr combined, it'd be better: (loop for (key . value) in (get-parameters*) when (string= key "task[]") collect value)
