Testing the Site.get_plugin_setting() method¶
Some use cases for testing the Site.get_plugin_setting()
method:
>>> settings.SITE.get_plugin_setting('foo', 'bar')
Traceback (most recent call last):
...
Exception: Plugin foo is not installed and no default was provided
>>> settings.SITE.get_plugin_setting('sales', 'bar')
Traceback (most recent call last):
...
AttributeError: 'Plugin' object has no attribute 'bar'
In both cases, you can avoid the traceback by specifying a default value:
>>> print(settings.SITE.get_plugin_setting('foo', 'bar', None))
None
>>> settings.SITE.get_plugin_setting('sales', 'bar', 'baz')
'baz'
