Description (last modified by )
When the translation engine provide an invalid plural rule the pluralidx
function can return invalid index which will cause the ngettext
to return value that does not exist - undefined
.
Same result can occur when the newcatalog
contains invalid values, for example:
const newcatalog = { '%s something': [], ... }
And in ngettext
we have:
django.ngettext = function(singular, plural, count) { const value = django.catalog[singular]; if (typeof value === 'undefined') { return (count == 1) ? singular : plural; } else { return value.constructor === Array ? value[django.pluralidx(count)] : value; } };
Which in case of empty array go for value[django.pluralidx(count)]
which is undefined.
I think we want the ngettext
function to return string always, if it does not find proper value in catalog, should default to the provided values.
It affects the previous versions too.
