Re: Is Overriding widget templates buggy?

2022-04-03 Thread Antonis Christofides 

Hi,

I'm not really an expert in that part. From what I can read in the 
documentation, TemplatesSetting isn't a template backend, so why do you think 
you can specify it in TEMPLATES[x]['BACKEND']? It appears to be a form renderer, 
which means you can specify it in FORM_RENDERER.


But of course I may have understood something wrong myself.

Regards,

Antonis

I was going to report a bug, but the guide recommends asking here first.

While trying to override a built in widget template (still stuck on it here: 
https://forum.djangoproject.com/t/overriding-widgets-templates-not-working-following-help-template-loader-not-searching-app-dirs/12974), 
I came across this weird behavoir:


In `django/forms/renderers.py` line 59 it has:
```
class TemplatesSetting(BaseRenderer):
    """
    Load templates using template.loader.get_template() which is configured
    based on settings.TEMPLATES.
    """
    def get_template(self, template_name):
        return get_template(template_name)
```
However a new project with:
```
TEMPLATES = [
    {
        'BACKEND': 'django.template.backends.django.DjangoTemplates',
        'DIRS': [],
        'APP_DIRS': True,
        'OPTIONS': {
            'context_processors': [
                'django.template.context_processors.debug',
                'django.template.context_processors.request',
                'django.contrib.auth.context_processors.auth',
'django.contrib.messages.context_processors.messages',
            ],
        },
    },
    {
        'BACKEND': 'django.forms.renderers.TemplatesSetting',
        'DIRS': ['/my/overide/dir/path',],
        'APP_DIRS': False,
    },
]
```

Generates the error:
```

How does one configure `django.forms.renderers.TemplatesSetting` without it 
throwing an error?
