Omaha Python Users Group Meeting, Nov 21, 2011

Tonight’s Meeting Topics:

• Django
• Django and RESTful interfaces via Piston and XML-RPC
• Message Queuing – specifically RabbitMQ, ActiveMQ and STOMP and the 5 primary usage patterns.  And integrating MQs in Django with Celery.
• We also had a “follow me” presentation on getting started with Selenium2‘s webdriver.  The following are my notes on the presentation:

-- Selenium2 --

Selenium RC vs Webdriver -
Selenium - http://seleniumhq.org/
         - http://seleniumhq.org/docs/03_webdriver.html
Why - http://seleniumhq.org/docs/appendix_migrating_from_rc_to_webdriver.html

Firefox, Chrome, Ie, iOS, Android, Opera

-- Setting up an environment --
  virtualenv --no-site-packages Se-Pres(entation)
  cd Se-Pres
  source bin/activate
  easy_install selenium
Now fire up an interpreter:
  python
  from selenium import webdriver
  b = webdriver.Firefox()
  b.get('http://www.google.com/')
  b.page_source
  dir(b)
  b.name
  b.get_cookies()   (a list of dicts, each containing a cookie and support info)
  b.current_url

>>> b.find_element_by_name('q')
<selenium.webdriver.remote.webelement.WebElement object at 0x874b22c>
>>> sbx = b.find_element_by_name('q')
>>> sbx.send_keys('omaha python')
>>> sbx.submit()
>>> b.title
u'omaha python - Google Search'

  b.find_element_by_name('foo')
selenium.common.exceptions.NoSuchElementException

-- Other Helpful things --
unittest - http://docs.python.org/library/unittest.html#
nose - http://readthedocs.org/docs/nose/en/latest/

nose-testconfig - http://pypi.python.org/pypi/nose-testconfig/

The meeting concluded about 9pm when the venue closed but we continued with a 15 minute parking lot track that included references to Code Complete and general development concepts.  Great Meeting! and everyone is looking forward to the next.
