Yeah, that example isn't particulary helpful. It's got code which
isn't used (such as the schema default) and it doesn't work
(MammothSize needs to inherit from grok.Adapter). Perhaps a more
simple example could be used ... but for now I've just removed the
example. I also *attempted* to clarify the usage of grok.adapts() with:
In the case of a simple adapter which only requires a single object
for adapation, the :func:`grok.context` directive is used to declare
the interface or class the adapter is for. It is only necessary to use
:func:`grok.adapts` to declare the adapation requirements for a multi
But for a simple adapter, one can:
- not declare the context when it's unambigous
- declare the context when it is ambigous, or delcare it for the
sake of declartion with grok.context()
- use grok.adapts() instead of grok.context()
So maybe the text should be updated to reflect that, or is there a
strong enough style conses that a particular method is used for
registering simple adapters (e.g. using grok.context over grok.adapts)?
