Composable selector/transform in snippet

[SevereOverfl0w]

I'm trying to make some pairs which can be reused easily within a snippet or template (the at form in general?)

I'm trying to handle setting values to their original value, when there is an error on the form, currently my code looks like:

(html/defsnippet form
  "templates/form.html" [:.container]
  [errors defaults] 
  [(html/attr= :name "name")] (html/set-attr :value (get defaults "name"))
  [(html/attr= :name "description")] (html/set-attr :value (get defaults "description"))
  [(html/attr= :name "image")] (html/set-attr :value (get defaults "image"))
  [:.errors] (html/content (pr-str errors)))

I'd like something a little more reusable, e.g.

(html/defsnippet form
  "templates/form.html" [:.container]
  [errors defaults]
  (somefn defaults ["name" "description" "image"])
  (somefn defaults "name") ;; Or this!
  [:.errors] (html/content (pr-str errors)))

I've tried returning a map from somefn, which didn't work, and I've been able to conjure up any other solution in it's place. I was hoping there might be some advice here?

I've come up with something somewhat reusable, whereby I use a nested at, and apply run on every node, but less than ideal:

(defn gen-defaults
  [m k]
  (fn [node]
    (html/at node
      [(html/attr= :name k)] (html/set-attr :value value))))

(html/defsnippet form
  "templates/form.html" [:.container]
  [errors defaults]
  [:*] (gen-defaults defaults "name")
  [:.errors] (html/content (pr-str errors)))
