AttributeError: 'dict' object has no attribute 'file_charset'

[Northshoot]

I followed simple example on from the docs, however, getting the error

  File "...../handlers.py", line 61, in request_arrived
    }, channel='userrequest', username='vdpo')
  File "...../e/lib/python3.6/site-packages/django_slack/api.py", line 76, in slack_message
    django_slack='django_slack/{}'.format(k),

    template = get_template(template_name, using=using)
  File ".....//lib/python3.6/site-packages/django/template/loader.py", line 15, in get_template
    return engine.get_template(template_name)

    with open(origin.name, encoding=self.engine.file_charset) as fp:

template:

{% extends django_slack %}

{% block text %}
Message text here: {{ foo }}
{% endblock %}

call

 slack_message('message.slack', {
            'foo': 'hello',
}, channel='bottest', username='mybot')

@Northshoot Huh, weird. Can you add some quck debugging? https://gist.github.com/lamby/f94302bd90e5aa0ab1d9815662c8c441/raw

[Northshoot]

sure thing

            print("TEMPLATE", repr(template))
            print("v", repr( v ))
            print("k", repr(k))

output

TEMPLATE 'message.slack'
v {'default': '', 'required': 0}
k 'text'

I am using Django 2 and python 3.6

[Northshoot]

I changed path in setting and removed

django.template.loaders.app_directories.Loader

So the error is gone and no error is given, however messages do not get posted.

I went for the native

python-slackclient

[lamby]

You will need django.template.loaders.app_directories.Loader for it to find django-slack's own internal templates -- that is a red herring and you will need to replace that :)

So, I can't reproduce this. Actually, looking at the traceback:

    with open(origin.name, encoding=self.engine.file_charset) as fp:
AttributeError: 'dict' object has no attribute 'file_charset'

Why is self.engine a dictionary? We don't set that in django-slack and I can't quite see how it could have broken it. Can you paste your entire TEMPLATES from your settings? Something is fishy there!

[lamby]

@Northshoot Any luck?

[Northshoot]

hey, I dropped this library and when with the native api.

[lamby]

@Northshoot Aw. Perhaps could you try again quickly? This is really the only way open source software can get fixed… especially as I can't seem to reproduce this :(

[lamby]

@Northshoot Any luck? :)

[lamby]

@Northshoot Just wondering if you'd had the chance to look at this yet? Would be great to get this fixed.

[lamby]

Okay, there's nothing really to do here alas.. :(

[lamby]

This looks like a different bug - it is about django.conf.settings.FILE_CHARSET. Are you using a very new version of Django?

[151henry151]

hi lamby -- yes i am using a very new version of django

[lamby]

Oh, it is whitenoise that is using the (deprecated) settings.FILE_CHARSET setting here, so this is surely a bug there:

File "/home/henry/EvergreenApp/venv/lib/python3.7/site-packages/whitenoise/django.py", line 48, in configure_from_settings
self.charset = settings.FILE_CHARSET

[let-clarence-code]

@lamby is there a timeline for a fix for this?

[lamby]

No timeline from me. As I currently understand it, this is a bug in whitenoise, not in django-slack...? I would speak to the whitenoise developers.
