Hi All,
I've started working with Chicagoboss quite recently. I've gone through the
cb_tutorial and it is working fine. Now I want cb_tutorial to run with
mnesia. I want to persist the data to my local directory. So far I've done
the following:
(1) Changed cb_tutorial boss.config with mnesia inputs - I have put a
nodename also called 'cb_tutorial" (created the directory also) as shown
below:
{session_adapter, mnesia},
{session_key, "_boss_session"},
{session_exp_time, 525600},
{session_cookie_http_only, false},
{session_cookie_secure, false},
{session_enable, true},
{session_mnesia_nodes, ['cb_tutorial@mynodename']}, % <- replace
"node()" with a node name
Also in the app configuration section I'm mentioning the directory path for
mnesia where data should persist:
{ cb_tutorial, [
{path, "../cb_tutorial"},
{base_url, "/"},
% {domains, all},
% {static_prefix, "/static"},
% {doc_prefix, "/doc"},
{mnesia, "/MyDirectory/Documents/Tests/amnesia/cb_tutorial"}, % I want
to persist the the data in this directory
{dummy, true}
]}
in DB configuration section:
{db_host, "localhost"},
{db_port, 1978},
{db_adapter, mnesia},
{db_username, "boss"},
{db_password, "boss"},
{db_database, "boss"},
In the priv/init directory I've put the util file that does all the
initialization stuff for mnesia
(https://github.com/ChicagoBoss/ChicagoBoss/wiki/Database-Setup).
Now I'm calling the init() at cb_tutorial_01_news.erl as:
init() ->
cb_tutorial_util:init(),
{ok, []}.
However, when running init-dev.sh I'm getting following error:

Am I missing something?
Thanking all in advance.
