I would agree if you take 'False' as a real string which shouldn't evaluate to
False, but I had the following templatetag called:
{% mytag "some string" False %}
Which now resolved in an error:
Traceback (most recent call last):
File "/usr/local/lib/python2.4/site-packages/django/template/__init__.py" in
render_node
702. result = node.render(context)
File "/usr/local/lib/python2.4/site-packages/django/template/__init__.py" in
render
830. resolved_vars = [resolve_variable(var, context) for var in
self.vars_to_resolve]
File "/usr/local/lib/python2.4/site-packages/django/template/__init__.py" in
resolve_variable
653. raise VariableDoesNotExist, "Failed lookup for key [%s] in %r" %
(bits[0], current) # missing attribute
VariableDoesNotExist at /ais/quittung/user/list/
Failed lookup for key [False] in
As I read the code the ' or " signs are remove later in the code and return the
resulting string. So 'False' would return the String False and False could not
be resolved and won't return String False.
I thing that it is a bug. And the changeset should be re-reverted to fix this.
In the other way with context_processors defining global variables False and
True variables this can be solved :)
Regards,
Dirk
