[Django]-Django Try Except Not Working

Please modify the code to this, run it and tell us what exception you are getting:

try:
    print "what"
    newClassName = CourseNameAndCodeAssociation.objects.get(departmentCode__iexact =         nameAndNumberStore[0])
    print newClassName  
except Exception as e:
    print "HAHA"
    print e

Also, it would probably help to have a debugger installed on your box. I can recommend Eclipse in combination with PyDev, but that is a personal choice. There are lots of great options out there.

Eclipse IDE – download the basic Java version of 120MB

then install this plugin on top of it – Pydev

Change it to:

except CourseNameAndCodeAssociation.DoesNotExist:

Each model you create gets its own DoesNotExist exception that extends core ObjectDoesNotExist exception.

Also the best approach is to only use try … except around the precise line that you expect to fail. A more pythonic way to write what you have there would be:

department_code = name_and_number_store[0]
class_names = CourseNameAndCodeAssociation.objects.all()
try:
    new_class_name = class_names.get(departmentCode__iexact=department_code)
except CourseNameAndCodeAssociation.DoesNotExist:
    print "HAHA"
else:
    search_term = u'%s %s' % (new_class_name.departmentName,
                              name_and_number_store[1])
    name_and_number_store = modify_search_term(search_term)
    url_store = modify_url(name_and_number_store)
    soup = get_html(url_store)
    store_of_books = scrape(soup, name_and_number_store)

Please also note that the convention in Python is to use lowercase_underscored_names for variables, attributes and function names and CamelCaseNames for class names (instance names are either variables or attributes).
