timed decorator crashes if kwargs_val contains a __proxy__ as item

[nerdoc]

I think this is no unicorn bug, but maybe a misconfig on my side, but anyway.

django-unicorn/django_unicorn/decorators.py

Line 33 in 07babfb

arguments = f"{arguments}{kwarg_key}={kwarg_val}, "

This line produces an error if kwargs_val is a proxy object, rendering unicorn unusable. I know it is only called when DEBUG is on.

__str__ returned non-string (type __proxy__)

The test component is just called with {% unicorn "medspeakaccount_detail" %} without args.

I have the following object in kwargs_vals.

if i render just f"{kwargs_vals}", I get the same error.

The error seems to occur when accessing f"...{kwarg_val}", rendering the variable into a string when it in reality is a proxy object. Maybe there are some strings translated with gettext_lazy in it.

Edit: I found the culprit, again after hours of searching and posting here, myself:
I have a model that is passed here:

from django.utils.translation import gettext_lazy as _
...

class AbstractSettings(SingletonModel):
    ...
    def __str__(self):
        return _("Settings")

Therefore the __str__ method returns a proxy object.

Yes, this was the answer too, sorry for the spam. the str method of a Model must not return a gettext_lazy(...) object. I solved it by using gettext(...) for this method.
