Hi,
I'm writing an LDAP plugin for my TG2 application. In this I wrote a small
class based decorator with args to set up a connection and call the necessary
functionality but I'm having problems with it. Here's my code:
class getConnection(object):
def __init__(self, settings, credentials):
self.settings = settings
self.credentials = credentials
def __call__(self, f):
def wrapped_f(*args, **kw):
...code snipped...
try:
if tls:
connection.start_tls_s()
if anon:
con.simple_bind_s()
else:
con.simple_bind_s( dn, pw )
except ldap.LDAPError, e:
print e.message['info']
else:
kw['conn'] = connection
try:
f(*args, **kw)
except Exception, e:
print 'Exception in Plugin execution: %s' % e
finally:
connection.unbind()
return wrapped_f
class LdapPlugin(Plugin):
...
def __init__(self, **kw):
Plugin.__init__(self)
@getConnection(self._settings, self.__cred__)
def search(self, **kw):
print 'Searching'
...
Here the base class constructor(Plugin) fetches plugin specific settings from
the web framework and stores it in self._settings and user info in
self.__cred__ . Now when the method is invoked, this is the error I get:
File '.../plugins/ldap/ldap/__init__.py', line 69 in LdapPlugin
@getConnection(self._settings, self.__cred__)
NameError: name 'self' is not defined
I can simply write a method that gets a connection and deal with it but I
wanted to know and learn why decorators is not working in this case.
Regards,
SZ
