5885	simple_tag is not compatible with _() syntax in templates	Dmitri Fedortchenko <zeraien@…>	nobody	"Creating a simple_tag decorated tag and then passing it a _('text') does not work.

The error produced is:
{{{
Failed lookup for key [_('links')]
}}} 

Code that produces this error:
{{{
@register.simple_tag
def title(text):
    return text.title()
}}}

{{{
{% title _('links') %}
}}}

Trace:

I noticed that the following works:
{{{
{{ _('Translate Me')|title }}
}}}
However the documentation only mentions that the following syntax is possible: 
{{{
{% some_special_tag _(""Page not found"") value|yesno:_(""yes,no"") %}
}}}

In any case, I believe that to make the behaviour of the _() syntax more consistent, it should work even with simple_tag.
I realise that my patch may duplicate some code, but it's the best I could come up with at the moment."		closed	Template system	dev		duplicate	i18n simple_tag translation internationalization templates documentation		Unreviewed	1	0	0	1	0	0
