The use of {{pass}} is explained
here: http://web2py.com/books/default/chapter/29/05/the-views#The-views.
Python usually defines code blocks based on indentation, but since the
views do not require proper Python indentation, we need an alternate way to
define code blocks when the boundaries are not otherwise obvious -- so you
use {{pass}} to indicate the end of a code block. For example:
{{if some_condition:}}
This
{{else:}}
That
{{pass}}
Now we are outside the "else" block, so this line will always be displayed.
Without the {{pass}}, that last line would be part of the "else" block and
therefore only display conditionally. Typically, you would need a {{pass}}
to indicate the end of an if, else, elif, or for block in a view.
