Install Erlang Cassandra Cqerl - cassandra

Question

I have a Cassandra cluster that I need to connect with Nitrogen? I installed Cqerl as instructed yet cannot make the connection. I do not think i installed the dependency correctly. When trying to make the connection from the console i get "undefined function cqerl".
I have run the "make test" and have got connect "failed".
Could someone guide me on installing the dependency and making the connection.

If you're using a standard Nitrogen installation, then adding the following line to your rebar.config in the "deps" section should properly bring in the cqerl dependency:
{cqerl, "", {git, "git://github.com/matehat/cqerl", {branch, master}}},
This should make the whole deps section of your rebar.config look something like this:
{deps, [
{cowboy, ".*", {git, "git://github.com/ninenines/cowboy", {tag, "1.0.1"}}},
%% CQERL Dependency
{cqerl, ".*", {git, "git://github.com/matehat/cqerl", {branch, master}}},
%% Uncomment the following lines and comment the bottom lines with specific
%% tags to always pull the latest versions
{simple_bridge, ".*", {git, "git://github.com/nitrogen/simple_bridge",{branch, master}}},
{nprocreg, ".*", {git, "git://github.com/nitrogen/nprocreg", {branch, master}}},
{nitrogen_core, ".*", {git, "git://github.com/nitrogen/nitrogen_core",{branch, master}}},
{sync, ".*", {git, "git://github.com/rustyio/sync", {branch, master}}}
]}.
I have no experience with cassandra or cqerl, so I can't give any advice on how to properly use cqerl, but that should get it installed as a dependency properly. If there are configs that need to be used, make sure to add them to your Nitrogen installation's etc directory.
