Hello Jimm
I've been testing the clojure library clj-record and it is very
usefull. But I have a question, I'm a 'noob' on clojure language and
I'm wondering if it is possible to write a macro or something to get
namespaces generated for every table in my database, for

definitely not my attention.
I should have realized I messed up the content of the files but
unfortunately had no clue what all these exceptions meant.
Therefore I really appreciate your detailed description of the
conclusion you draw

I hope you also learned a bit about error messages. ;)
"No such var: user/create": That means you get past the namespace
declaration. Hence they load fine. But in the user namespace the

Evaluating your suggested declaration:

More evidence for a problem with the user alias. Try a different one
like (:require [active-record.user :as u]).

You are right, there was a syntax error in charge.clj. However, after

Are you sure, that you don't have some syntax error somewhere?

Dear Clojure group,
I am currently reading chapter 9.1 MySQL & clj-record of 'Clojure in
Action'.
clj-record seems pretty awesome, but I once again got lost in
namespace jungle.
Here is a concrete example:

Hi Emeka,
Sorry for the slow response. I don't get that message with the latest
clojure, clojure-contrib, and clj-record. (load-file just returns
nil.)
What version of clojure are you running? Do you have the base
directory of clj-record on your classpath?
Also, that file just contain
user=> (load-file "clj_record/core.clj")
I got clj_record/util not in system path. Why is it so?

That's an interesting idea. On the one hand it seems weird to m
John,
I was looking at the validates method and I had a thought I'd bounce off
you. Instead of
just returning a hash of errors what about returning the record with the
errors hash in
the metadata? That way you just have the data and the errors in one
"object" similar
to an ActiveRecord model.
Looks good. I didn't know about the *file* var.

I was looking around at your tests just to get a feel for using the test-is

I think that's a good idea actually and like it better than my solution to
putting the
callbacks in the model namespace.

Hi all,
As a learning exercise, I've started working on a sort of clojure
clone of ActiveRecord (from Rails). You can see it here:
http://github.com/duelinmarkers/clj-record/tree/master
The model used in the tests is defined in files here:
