What about this? First, use :title and :body keywords instead of
"title" and "body" strings as keys in form-params. Then define this
utility function:
(defn get-seq [m & kws]
((apply juxt kws) m))
which takes a map and one or more keywords (cannot be other types of
key) and returns a seq (actually a vector) of the corresponding
values, in order; do this
(defn new-article [path timestamp title body]
(Article. path title body timestamp))
so you can use apply. And then this:
(defn save-article
[path form-params timestamp]
(ds/save!
(apply new-article path timestamp
(get-seq form-params :title :body))))
is neat and tidy and easily extensible to added form-params later (add
them to the end of new-article's arg list and to the get-seq keyword
list in the same order; pass them to the amended Article constructor
appropriately).
