I am trying to access an online simulation through Pearson's MyMIS Lab for an online class. I was using this simulation a couple of days ago but when I logged on this morning, the simulation would not open. I have copy and pasted the error message that pops up when I try to access it. At the bottom, it reads "You're seeing this error because you have DEBUG = True in your Django settings file. Change that to False, and Django will display a standard 500 page." I have no idea what Django settings are and have researched how to change the setting but I am not familiar with this at all. Any help would be greatly appreciated so I can get my homework finished! Thank you!!!! <pre><nowiki>AttributeError at /simLaunch/launch/ 'Settings' object has no attribute 'XLSIMS_LAUNCH_URL' Request Method: POST Request URL: http://econdip.pearsoncmg.com/xlsim/simLaunch/launch/ Django Version: 1.5.2 Exception Type: AttributeError Exception Value: 'Settings' object has no attribute 'XLSIMS_LAUNCH_URL' Exception Location: /vh/docroots/econdip.pearsoncmg.com/prod/virtualenv/lib/python2.6/site-packages/django/conf/__init__.py in __getattr__, line 54 Python Executable: /usr/bin/python Python Version: 2.6.6 Python Path: ['/vh/docroots/econdip.pearsoncmg.com/prod/virtualenv/lib/python2.6/site-packages', '/usr/lib64/python26.zip', '/usr/lib64/python2.6', '/usr/lib64/python2.6/plat-linux2', '/usr/lib64/python2.6/lib-tk', '/usr/lib64/python2.6/lib-old', '/usr/lib64/python2.6/lib-dynload', '/usr/lib64/python2.6/site-packages', '/usr/lib64/python2.6/site-packages/gtk-2.0', '/usr/lib/python2.6/site-packages', '/usr/lib/python2.6/site-packages/setuptools-0.6c11-py2.6.egg-info', '/vh/docroots/econdip.pearsoncmg.com/prod/server/glservice'] Server time: Sat, 30 Aug 2014 14:59:46 -0500 Environment: Request Method: POST Request URL: http://econdip.pearsoncmg.com/xlsim/simLaunch/launch/ Django Version: 1.5.2 Python Version: 2.6.6 Installed Applications: ('django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.sites', 'django.contrib.messages', 'django.contrib.staticfiles', 'django.contrib.admin', 'gldata', 'econ.ca', 'econ.ue', 'gllaunch', 'datacapture', 'xlsims') Installed Middleware: ('django.middleware.common.CommonMiddleware', 'django.contrib.sessions.middleware.SessionMiddleware', 'django.middleware.csrf.CsrfViewMiddleware', 'django.contrib.auth.middleware.AuthenticationMiddleware', 'django.contrib.messages.middleware.MessageMiddleware') Traceback: File "/vh/docroots/econdip.pearsoncmg.com/prod/virtualenv/lib/python2.6/site-packages/django/core/handlers/base.py" in get_response 115. response = callback(request, *callback_args, **callback_kwargs) File "/vh/docroots/econdip.pearsoncmg.com/prod/virtualenv/lib/python2.6/site-packages/django/views/decorators/csrf.py" in wrapped_view 77. return view_func(*args, **kwargs) File "/vh/docroots/econdip.pearsoncmg.com/prod/server/glservice/xlsims/views.py" in launchSim 23. if TPIUtils.has_valid_signature(launch_data, url=settings.XLSIMS_LAUNCH_URL, key='bphsc2014'): File "/vh/docroots/econdip.pearsoncmg.com/prod/virtualenv/lib/python2.6/site-packages/django/conf/__init__.py" in __getattr__ 54. return getattr(self._wrapped, name)</nowiki></pre>
