Hey Sean,
maybe you could clarify some choices made in 0.3, I needed to rewrite some
SQL bits of my app anyhow and thought it was a good time to ditch 0.2.3 as
well.
1) Why the keyword args to most functions? entities/identifiers in
particular. My SQL Tables have columns like "created_at", "created_by",
since SQL doesnt like "-" as separators, I still want to use "-" in Clojure
so on insert I do
(j/insert! db table {:created-by 1, :name "test"} :entities #(str/replace %
#"-" "_"))
All is fine until I want to use the return value of insert (aka the
inserted record + the generated id) which then equals
{:created_by 1, :name "test", :id 1} notice the "incorrect" underscore.
In my case it would be sufficient if I could use the db map to specify this
behavior, and one could still override this by just doing
(j/insert! (assoc db :identifiers some-fn) table record). I realize that db
is a "Connectable" and not always a map, but since its forced to a map
under the hood anyways why not force it outside too.
2) Transaction Management? I dont quite understand what the point of the
":transaction?" option is since you should be able to infer this
information at runtime? Seems to basically duplicate what
Connection.setAutoCommit already does?
Apart from these issues the API looks a lot nicer.
Regards,
/thomas
