I'm trying to write a simple GUI front end for Plurk using pyplurk.
I have successfully got it to create the API connection, log in, and retrieve and display a
list of friends. Now I'm trying to retrieve and display a
list of Plurks.
pyplurk provides a GetNewPlurks function as follows:
def GetNewPlurks(self, since):
'''Get new plurks since the specified time.
Args:
since: [datetime.datetime] the timestamp criterion.
Returns:
A PlurkPostList object or None.
'''
offset = jsonizer.conv_datetime(since)
status_code, result = self._CallAPI('/Polling/getPlurks', offset=offset)
return None if status_code != 200 else \
PlurkPostList(result['plurks'], result['plurk_users'].values())
As you can see this returns a PlurkPostList, which in turn is defined as follows:
class PlurkPostList:
'''A
list of plurks and the set of users that posted them.'''
def __init__(self, plurk_json_list, user_json_list=[]):
self._plurks = [PlurkPost(p) for p in plurk_json_list]
self._users = [PlurkUser(u) for u in user_json_list]
def __iter__(self):
return self._plurks
def GetUsers(self):
return self._users
def __eq__(self, other):
if other.__class__ != PlurkPostList: return False
if self._plurks != other._plurks: return False
if self._users != other._users: return False
return True
Now I expected to be able to do something like this:
api = plurk_api_urllib2.PlurkAPI(open('api.key').read().strip(), debug_level=1)
plurkproxy = PlurkProxy(api, json.loads)
user = plurkproxy.Login('my_user', 'my_pass')
ps = plurkproxy.GetNewPlurks(datetime.datetime(2009, 12, 12, 0, 0, 0))
print ps
for p in ps:
print str(p)
When I run this, what I actually get is:
<plurk.PlurkPostList instance at 0x01E8D738>
from the "print ps", then:
for p in ps:
TypeError: __iter__ returned non-iterator of type '
list'
I don't understand - surely a
list is iterable? Where am I going wrong - how do I
access the Plurks in the PlurkPostList?
