I have a separate process that I run along with my web application by
creating a subprocess like so:
subprocess.Popen("python web2py.py -v -e -a admin -i 0.0.0.0 -p
8080 -c <cert_file> -k <key_file>".split())
subprocess.Popen("python web2py.py -S <app_name> -M -R <path_to_process>
".split())
In that process, I start a thread to do some tasks. I have assigned the
callbacks from that thread to the callbacks in that process:
Class Process:
def __init__(self):
self.thread = MyThread() #MyThread is a threading.Thread object
self.thread.callback = self.callback
self.thread.start()
def self.callback(self, event):
print db(auth_user.id=1).first_name
In the self.callback, when I try to read from the database using the db
object I get the following error:
AttributeError: 'thread._local' object has no attribute
'_pydal_connection_55197392_9964'
I have tried making the db object a member of the Process class and then
trying to access it in the callback:
Class Process:
def __init__(self):
self.db = db
self.thread = Threading.thread()
self.thread.callback = self.callback
self.thread.start()
def self.callback(self, event):
print self.db(auth_user.id=1).first_name
I still get the same error.
How can I access the database from inside a thread created inside a process
running in a shell?
