While developing, inserting the following line to your code:
assert False, value
will cause django to raise an
AssertionError with the value supplied as an error message when this line is executed.
If this occurs in a view, or in any code called from a view, and
DEBUG=True is set, a full and detailed stacktrace with a lot of debugging information will be displayed in the browser.
Don't forget to remove the line when you are done!
