I'm not really sure what's going on there, but when you use
map.resource, you can do this instead of adding a special `json`
action:
GET /post/1.json
Then 'json' will be passed as the `format` arg to the appropriate REST
action. In this example:
def show(self, id, format='html'):
# id is '1' and format is 'json'
# ...
if format == 'json':
# convert member to json and return it
