Following this <a href="https://stackoverflow.com/questions/1954402/ejabberd-supervisor-module">stackoverflow question</a>, and <a href="http://anders.conbere.org/blog/2008/08/06/building_ejabberd_modules_-_part_4_-_xmpp_bots/" rel="nofollow noreferrer">this tutorial series</a>, I implemented mod_test module, which implements both gen_mod and gen_server behaviours. It is very stupid for now, since it does nothing more that adding itself to ejabber_sup. My problem is that I am not sure whether the module is started by ejabberd_sup or not since I can't find it in the list provided by: <pre><code>supervisor:which_children(ejabberd_sup). </code></pre> Given that I have gen_mod.beam and mod_test.erl in the same directory, I compiled my code using: <pre><code>erlc -pa ./ mod_test.erl </code></pre> and this gives no errors. After compilation, I copied the file into ebin folder of ejabberd installation and changed ejabberd.cfg adding: <pre><code>.... {mod_test, []}, .... </code></pre> My code is the following: <pre><code>-module(mod_test). -behaviour(gen_server). -behaviour(gen_mod). -export([start/2, stop/1]). -export([start_link/2]). -export([init/1, handle_call/3, handle_cast/2, handle_info/2, terminate/2, code_change/3]). -record(state, {}). start(Host, Opts) -> Proc = gen_mod:get_module_proc(Host, ?MODULE), ChildSpec = {Proc, {?MODULE, start_link, [Host, Opts]}, permanent, 1000, worker, [?MODULE]}, supervisor:start_child(ejabberd_sup, ChildSpec). stop(Host) -> Proc = gen_mod:get_module_proc(Host, ?MODULE), supervisor:terminate_child(ejabberd_sup, Proc), supervisor:delete_child(ejabberd_sup, Proc). start_link(_Host, _Opts) -> gen_server:start_link({local, ?MODULE}, ?MODULE, [], []). init([]) -> {ok, #state{}}. handle_call(_Request, _From, State) -> Reply = ok, {reply, Reply, State}. handle_cast(_Msg, State) -> {noreply, State}. handle_info(_Info, State) -> {noreply, State}. terminate(_Reason, _State) -> ok. code_change(_OldVsn, State, _Extra) -> {ok, State}. </code></pre> Is something wrong in my approach? How can I be sure that the module is correctly started?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
