CategoryManager | Thunderbird Add-On ] Category Manager

I have created a custom user class which appears to be working correctly however whenever I try to log in to the admin, I keep getting the following error on the login page:

Please enter the correct username and password for a staff account. Note that both fields may be case-sensitive.

I have already created several superuser which are all saving to the DB correctly with the is_staff/is_superuser/is_active flags set to True as you can see below:

i am working with django's nested self referential objects and i have following Category model

I am using Parler for localizing my models.

Django Admin works fine, but now I want to recreate the admin forms in the frontend.

So far, I can create a new model but it is always created in the default language. The question now is, how can I set the language?

Best case scenario would be, that I can select the language via in the form, but the default value would be set by a get param language=iso_code or if it is way easier using the language tabs like in Django Admin. EDIT: The problem seems to be somewhere in the form class. Model class Category(MPTTModel, TranslatableModel): title = TranslatedField(any_language=True) description = TranslatedField() slug = TranslatedField() parent = TreeForeignKey('self', on_delete=models.CASCADE, null=True, blank=True, related_name='children', db_index=True) objects = CategoryManager() def save(self, *args, **kwargs): super(Category, self).save(*args, **kwargs) class CategoryTranslation(TranslatedFieldsModel): title = models.CharField(max_length=200) description = models.TextField(null=True) slug = models.SlugField() master = models.ForeignKey(Category, on_delete=models.CASCADE, related_name='translations') class Meta: unique_together = ( ('language_code', 'slug'), ) View @method_decorator(login_required, name='dispatch') class CategoriesCreateView(TranslatableCreateView): model = Category context_object_name = 'categories' template_name = 'categories/update.html' form_class = CategoryForm object = Category() def get(self, request, *args, **kwargs): request.DEFAULT_LANGUAGE = LANGUAGE_CODE request.meta_title = _('Create Category') return super().get(request, *args, **kwargs) def post(self, request, *args, **kwargs): request.DEFAULT_LANGUAGE = LANGUAGE_CODE request.meta_title = _('Create Category') return super().post(request, *args, **kwargs) Form class CategoryForm(TranslatableModelForm): use_required_attribute = False title = TranslatedField() description = TranslatedField() slug = TranslatedField() parent = TreeNodeChoiceField(queryset=Category.objects.all()) def __init__(self, *args, **kwargs): self.helper = FormHelper() self.helper.form_method = 'post' self.helper.form_action = '.' self.helper.form_class = 'form-horizontal form-bordered' self.helper.label_class = 'col-lg-3' self.helper.field_class = 'col-lg-8' self.helper.layout = self.__get_layout() super().__init__(*args, **kwargs) self.fields['parent'].required = False @staticmethod def __get_layout(): layout = Layout( Field('parent'), Field('title'), Field('slug'), Field('description'), ButtonHolder( Submit('submit', _('Save')) ) ) return layout class Meta: model = Category fields = ['title', 'description', 'slug', 'parent']

I am a newbie in Django and I am building a quiz application. I want to be able to import some questions from a CSV file in Django using the import_export.admin method on the admin site, When I try to import, the contents of my CSV file which contains the list of questions does not append to my existing list of questions, instead, it throws an error "invalid literal for int() with base 10: 'Independence'."

I have tried changing the format of the CSV file I am uploading from comma-separated Values to CSV UTF-8(Comma-delimited). I also tried using integers in the 'Category' column, but it gives a 'Traceback (most recent call last) Category matching query does not exist' error. Any help?
