I can not to get normal __str__ method from safe_string.
Fro example:
{{{
@html_safe
class TranslatableText(str):
"""Class like a string but returns values depends on get_language."""
}}}
After that str(TranslatableText) is always SafeString. If i want call old
__str__ method it is not possible: html_safe destroy it in
django\utils\html.py, rows 376-378
{{{
klass_str = klass.__str__
klass.__str__ = lambda self: mark_safe(klass_str(self))
klass.__html__ = lambda self: str(self)
return klass
}}}
But it is easy to repair:
{{{
klass._old_str_method = klass.__str__
klass.__str__ = lambda self: mark_safe(klass._old_str_method(self))
klass.__html__ = lambda self: str(self)
return klass
}}}
After that, not only can i get SafeString object, it is also possible to
call klass._old_str_method and get BaseString object
