Enum is not usable in templates.

[David Marogy]

Hello,

i tried using an normal Enum instead of a Textchoice in my Django-Template. I created a therefore simple tag which gets an enum(ModuleKind.SCHADENSANALYSE) and some other inputs. This resulted in getting an empty string string instead of an Enum. Searching for a way to solve this problem i stumbled upon ​https://stackoverflow.com/questions/35953132/how-to-access-enum-types-in-django-templates, which suggested a hack.

 {% module_info_tiles user ModuleKind.SCHADENSANALYSE versdb_1_host "servicebots/index.html?bot_id=1327" "Schadenanalyse" %}

Digging a little bit deeper, the same issue happend for enum types for another ticket: https://code.djangoproject.com/ticket/31154

The solution would be the same as in the previous ticket, making the Enum not callable in templates.

Best Regards
David

Unlike Django's choices enum subclasses that we were able to adjust in #31154, Python's Enum type isn't something we can add attributes to in Django.

The decorator suggestion on the SO thread seems like a way to go. (Equally you can add the attribute by hand in e.g. get_context_data).
