    <p>I am having an issue with accessing the queue object within my class in multiple functions, the following code might show you what i am trying to do;</p> <pre><code>import MySQLdb import socket, sys from struct import * import threading import sched, time from datetime import datetime from copy import deepcopy import Queue IP = {} class QP: def __init__(self): self.jobs = Queue.Queue() # this function runs every 10 seconds # and processes any queued data. def processQueue(self): print(self.jobs.qsize()) time.sleep(5) if self.jobs.empty(): print("No items in queue") else: IP_TEMP = {} IP_TEMP = self.jobs.get() IP_TEMP_QUEUE = {} IP_TEMP_QUEUE = IP_TEMP try: cnx = #connect to database cursor = cnx.cursor() for k, v in IP_TEMP.iteritems(): #there is some code here, but its not the issue try: cursor.execute(add_packet, data_packet) cnx.commit() print("Task Done") except: print("Query failed, skipping") break except: self.queueJobs(IP_TEMP_QUEUE) IP = {} self.jobs.task_done() self.processQueue() # this function is called by other modules to add data def queueJobs(self, data): self.jobs.put(data) print(self.jobs.qsize()) return True </code></pre> <p>This is how i call the queueJobs method in the other modules:</p> <pre><code>self.process.queueJobs(IP_TEMP_QUEUE) </code></pre> <p>Now, the main issue is that the <code>processQueue()</code> function always returns that there is no jobs in the queue, even though they have been added below in the <code>queueJobs()</code> function.</p> <p>Any help would be great!</p>

    1. COAccording to the current indentation `queueJobs()` is *not* part of the class you defined

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
