Thanks Chris,
didn't realize about the implicit GET when calling the attribute :(
I think I'll put the get call on __repr__, __str__ and __getattr__,
something like
class HTTPAttribute(object):
""" functional endpoint representation """
def __repr__(self):
self._retrieve()
return json.dumps(self.__dict__)
def __str__(self):
self._retrieve()
return json.dumps(self.__dict__)
def __init__(self, resource, uri):
self._resource = resource
self.uri = uri
def __call__(self, *args, **kwargs):
return self._resource._api.post(self.uri, *args, **kwargs).content
def __getattr__(self, name):
self._retrieve()
if hasattr(self, name):
return getattr(self, name)
raise AttributeError("'%s' object has no attribute '%s'" %
(str(type(self)), name))
def _retrieve(self):
resource = self._resource._api.retrieve(self.uri)
for key, value in resource._data.iteritems():
setattr(self, key, value)
and that's it,
But still I'll reconsider an interface with less magic :P
