Eclipse+PyDev+GAE memcache error
- by bocco
I've started using Eclipe+PyDev as an environment for developing my first app for Google App Engine. Eclipse is configured according to this tutorial.
Everything was working until I start to use memcache. PyDev reports the errors and I don't know how to fix it:
Error: Undefined variable from import: get
How to fix this?
Sure, it is only PyDev checker problem. Code is correct and run on GAE.
UPDATE:
I'm using PyDev 1.5.0 but experienced the same with 1.4.8.
My PYTHONPATH includes (set in Project Properties/PyDev - PYTHONPATH):
C:\Program Files\Google\google_appengine
C:\Program Files\Google\google_appengine\lib\django
C:\Program Files\Google\google_appengine\lib\webob
C:\Program Files\Google\google_appengine\lib\yaml\lib
UPDATE 2:
I took a look at C:\Program Files\Google\google_appengine\google\appengine\api\memcache\__init__.py and found get() is not declared as memcache module function. They use the following trick to do that (I didn't hear about such possibility):
_CLIENT = None
def setup_client(client_obj):
"""Sets the Client object instance to use for all module-level methods.
Use this method if you want to have customer persistent_id() or
persistent_load() functions associated with your client.
Args:
client_obj: Instance of the memcache.Client object.
"""
global _CLIENT
var_dict = globals()
_CLIENT = client_obj
var_dict['set_servers'] = _CLIENT.set_servers
var_dict['disconnect_all'] = _CLIENT.disconnect_all
var_dict['forget_dead_hosts'] = _CLIENT.forget_dead_hosts
var_dict['debuglog'] = _CLIENT.debuglog
var_dict['get'] = _CLIENT.get
var_dict['get_multi'] = _CLIENT.get_multi
var_dict['set'] = _CLIENT.set
var_dict['set_multi'] = _CLIENT.set_multi
var_dict['add'] = _CLIENT.add
var_dict['add_multi'] = _CLIENT.add_multi
var_dict['replace'] = _CLIENT.replace
var_dict['replace_multi'] = _CLIENT.replace_multi
var_dict['delete'] = _CLIENT.delete
var_dict['delete_multi'] = _CLIENT.delete_multi
var_dict['incr'] = _CLIENT.incr
var_dict['decr'] = _CLIENT.decr
var_dict['flush_all'] = _CLIENT.flush_all
var_dict['get_stats'] = _CLIENT.get_stats
setup_client(Client())
Hmm... Any idea how to force PyDev to recognize that?
