Comment (by charettes):
techtonik, I know you stated you need to distinguish between {{{closed ==
None}}} and {{{closed == False}}} in #17229 but I can't find that
statement in the above description. You only state that ''you want string
* * * * to show only if closed is True.'' which is the question ptone
answered to.
Why not use the solution proposed by lukeplant in #17229
{{{
{% if closed == None %}
Works since None is an undefined variable
{% else %}{% if closed %}
True
{% else %}
False
{% endif %}{% endif %}
}}}
IMHO the main reason why boolean expressions are not allowed in there is
because they are not mandatory. Don't you think that {{{{% if closed %}}}}
makes more sense than {{{{% if closed == True %}}}}? It might be the
reason why not so many people stumbled on this.
