Debugging toolbar for Zotonic implemented as a module.
Shamelessly ripped off from the Django Debug Toolbar :-)
Basically, what it does is to add a diagnostics toolbar to Zotonic applications. When enabled, it injects an html div to the right side of the web application with easy access to logging, database queries, request variables, session/cookie data, application modules, Erlang runtime info, and other useful information.
- Modules: path, status, dependencies
- Request vars [GET, POST, session, cookies, http headers]
- Settings - site configs
- Message logs
- Template context variables
- Resource usage
- Sql profiler
- Process Info:
- URL dispatch
Insert {% debug_toolbar %} in a template file, preferably the base template file(base.tpl).
A better approach will be add a debug key to the site config: {debug, true}, and then add the following to base.tpl:
{% if m.site.debug %}
{% debug_toolbar %}
{% endif %}
The following configs keys can be set via the Zotonic site dashboard's configuration page. The module should be, mod_zdt and the key, value pairs as follows:
-
address: Peer addresses to display the debug toolbar to.
Example: 127.0.0.1, ::1, localhost, 23.45.87.7
Use "*" to enable all access
-
panels: Panels to display
Example: message_log, system, modules. sql
Panels names: stats, configs, dispatch, sql, http_vars, templates, modules, logs, system To enable all, leave the panels config blank or set "*"
OR in your Erlang shell: m_config:set(mod_zdt, address, "78.23.455.1, 23.45.87.7", Ctx).
- SQL profiler: displays the queries made by the current request, and profile them by execution time.
- Events [observers and notifications]
