Using it with Pluggables
Like any other pluggable extension, the debugbar can be activated through the pluggables interface inside your app_cfg.py:
from tgext.pluggable import plug plug(base_config, 'tgext.debugbar')
The debugbar will then check for the debug config option disabling itself when it is false.
Using it without pluggable
While the pluggables interface makes convenient to pass options to the debugbar, you might want to avoid using it for various reasons. In such cases you can enable the debugbar by adding the following lines to your project app_cfg.py:
from tgext.debugbar import enable_debugbar enable_debugbar(base_config)
Whenever your response is JSON or an ajax request, or any other kind of content which is not a plain HTML page, the debugbar bar is not injected inside your response. This is to prevent it from messing with your output when it would probably break things.
There are cases when you might be interested in getting access to some informations from the debugbar even when your output is not HTML. For example your might be interested in knowing which queries have been performed to retrieve your JSON response.
To enable logging such informations you can pass the enable_logs=True option to the plug call which activates the debugbar.
The DebugBar provides the inventing mode, such feature is inspired by the Inventing On Principle to speed up experimenting and prototyping with your website. Whenever the inventing mode is enable your web page will automatically update when you change it, being it a controller, template or css change.
The inventing mode can be enabled by passing the inventing=True option to the plug call which activates the debugbar.
If you want to disable inventing mode for CSS files, you can enable the inventing mode and then pass the inventing_css=False option.
